Rubik's Magic
View on Wikipediafrom Wikipedia
Rubik's Magic, like the Rubik's Cube, is a mechanical puzzle invented by Ernő Rubik and first manufactured by Matchbox in the mid-1980s.
The puzzle consists of eight black square tiles (changed to red squares with goldish rings in 1997) arranged in a 2 × 4 rectangle; diagonal grooves on the tiles hold wires that connect them, allowing them to be folded onto each other and unfolded again in two perpendicular directions (assuming that no other connections restrict the movement) in a manner similar to a Jacob's ladder toy. The front side of the puzzle shows, in the initial state, three separate, rainbow-colored rings; the back side consists of a scrambled picture of three interconnected rings. The goal of the game is to fold the puzzle into a heart-like shape and unscramble the picture on the back side, thus interconnecting the rings.
Numerous ways to accomplish this exist, and experienced players can transform the puzzle from its initial into the solved state in less than 2 seconds.[1] Other challenges for Rubik's Magic include reproducing given shapes (which are often three-dimensional), sometimes with certain tiles required to be in certain positions and/or orientations.
History
[edit]Rubik's Magic was first manufactured by Matchbox in 1986. Professor Rubik holds both a Hungarian patent (HU 1211/85, issued 19 March 1985) and a US patent (US 4,685,680, issued 11 August 1987) on the mechanism of Rubik's Magic.
In 1987, Rubik's Magic: Master Edition was published by Matchbox; it consisted of 12 silver tiles arranged in a 2 × 6 rectangle, showing 5 interlinked rings that had to be unlinked by transforming the puzzle into a shape reminiscent of a W. Around the same time, Matchbox also produced Rubik's Magic Create the Cube,[2] a "Level Two" version of Rubik's Magic, in which the puzzle is solved when folded into a cube with a base of two tiles, and the tile colors match at the corners of the cube.[3] It did not have as wide a release, and is rare to find.
In 1996, the original version of Rubik's Magic was re-released by Oddzon, this time with yellow rings on a red background; other versions (for example, a variant of the original with silver tiles instead of black ones) were also produced, and there also was a strategy game based on Rubik's Magic. An unlicensed 2 × 8 version was also produced, with spheres printed on its tiles instead of rings. Custom versions as large as 2 × 12 have been built using kits available from Oddzon.
Details
[edit]
It can be seen that the total number of 2 × 4 rectangles that can possibly be created using Rubik's Magic is only thirty-two; these can be created from eight distinct chains. The easiest way to classify chains is by the means of the middle tile of the puzzle's finished form (the only tile that has segments of all three rings) and the tile next to it featuring a yellow/orange ring segment (the indicator tile).
Every chain either has the middle tile on the outside (O) or the inside (I) of the chain; if it is arranged so that the indicator tile is to the right of the middle tile, then the position of the ring segment on the indicator tile can either be the upper left (UL), upper right (UR), lower left (LL), or lower right (LR) corner. The position and orientation of the remaining tiles are then determined by the middle and indicator tiles, and eight distinct chains (OUL to ILR) are obtained, although the naming convention is not standardized.
Similarly, the 2 × 4 rectangle forms of them can be categorized. Each of these forms has exactly one chain associated with it, and each chain yields four different rectangle forms, depending on the position of the edge where it is folded with regard to the middle tile. By concatenating one of the numbers 0, 1, 2, or 3 to the chain's name, depending on whether the number of tiles to the right of the middle tile before the folding edge, a categorization of the rectangle forms is obtained. The starting position, for example, is rectangle form OUR2. The cube now is rainbow and has silver rings. A game rule for this one is you can match the silver rings and color squares, which can make it more complicated. A similar classification can also be obtained for the heart-shaped forms of the puzzle, of which 64 exist.
Analysis
[edit]One question when analyzing Rubik's Magic concerns its state space: What is the set of configurations that can be reached from the initial state? This question is harder to answer than for Rubik's Cube, because the set of operations on Rubik's Magic does not form a mathematical group.
The basic operation (move) consists of transferring a hinge between two tiles T1 and T2, from one pair of edges (E11 of T1 and E21 on T2) to another pair E12 and E22. Here, edges E11 and E12 are adjacent on tile T1, and so are edges E21 and E22 on tile T2 but in opposite order. See the figure below for an example, where E11 is the East edge of the yellow tile, E21 is the West edge of the red tile, and both E21 and E22 are the North edges.
In order to carry out such a move, the hinge being moved cannot cross another hinge. Thus, the two hinges on a tile can take up one of five relative positions (see figure below). The positions are encoded as a number in the range from -2 to +2, called the wrap. The difference between wrap -2 and wrap +2 is the order of the neighboring tiles (which one is on top). The total wrap of a configuration is calculated as the alternating sum of the wraps of the individual tiles in the chain.
The total wrap is invariant under a move. Thus, one can calculate the number of theoretically possible shapes of the chain (disregarding the patterns on the individual tiles) as 1351.[4]
Furthermore, the other tiles in the chain will have to move through space appropriately to allow the folding and unfolding needed to carry out a move. This limits the practically reachable number of configurations further. That number also depends on how much stretching of the wires you tolerate.
Records
[edit]The world record for a single solve of the Magic is 0.69 seconds, set by Yuxuan Wang. Yuxuan Wang also holds the record for an average of five solves - 0.76 seconds set at the Beijing Summer Open 2011 competition.[5] Due to the World Cube Association no longer recognizing Rubik's Magic as an official event in 2012, Yuxuan Wang holds the permanent world record for this puzzle.

Rubik's Magic: Master Edition
[edit]
Rubik's Magic: Master Edition (most commonly known as Master Magic) was manufactured by Matchbox in 1987. It is a modification from the Rubik's Magic, with 12 tiles instead of the original's 8. The puzzle has 12 panels interconnected with nylon wires in a 2 × 6 rectangular shape, measuring approximately 4.25 inches (10.5 cm) by 13 inches (32 cm). The goal of the game is the same as for Rubik's Magic, which is to fold the puzzle from a 2 × 6 rectangular shape into a W-like shape with a certain tile arrangement. Initially, the front side shows a set of 5 linked rings. Once solved, the puzzle takes the shape of the letter W, and shows 5 unlinked rings on the back side of the previous initial state.[6]
As a puzzle, the Master Edition is actually simpler than the original Rubik's Magic. With more hinges, the player can work on one part, mostly ignoring the other parts. The minimal solution involves 16 quarter-turn moves.[7] There are multiple solutions.[6] The puzzle was an official World Cube Association (WCA) event from 2003 to 2012.[8]

History
Invention and Patenting
Ernő Rubik, a Hungarian architect and professor renowned for inventing the Rubik's Cube in 1974 to aid students in visualizing three-dimensional spatial movements, extended his exploration of mechanical puzzles into two dimensions with Rubik's Magic during the mid-1980s. Motivated by the desire to create an entertaining mechanical puzzle that allowed for complex rearrangements through folding and rotation, Rubik designed the puzzle as a series of interconnected tiles that could form various planar configurations, building on the success of his earlier work while simplifying the mechanics to a flat structure.[5][6] The development of Rubik's Magic began with conceptual work and prototyping in Hungary in the early to mid-1980s, shortly after Rubik established his design studio in 1983 to pursue further innovations in puzzle mechanics. This timeline culminated in the filing of a Hungarian patent (HU 1211/85) on 19 March 1985, which protected the core mechanism of tiles linked by wires in diagonal grooves for multi-directional folding.[1][6] The international expansion followed with a U.S. patent application filed on 28 July 1986 and granted on 11 August 1987 (US 4,685,680), detailing the system's ability to enable "migrating" rotation axes for enhanced puzzle complexity.[5] Following the patent protections, Rubik partnered with the toy manufacturer Matchbox for the initial production and distribution of Rubik's Magic, marking the puzzle's transition from prototype to commercial product in 1986. This collaboration leveraged Matchbox's expertise in mechanical toys to bring the 2x4 tile array—featuring rings or images for solving challenges—to market, establishing legal safeguards that supported its global rollout.[1]Commercial Release and Popularity
Rubik's Magic was first manufactured by Matchbox International Ltd. and released worldwide in October 1986, following Ernő Rubik's invention as a successor to the iconic Rubik's Cube. The puzzle was produced in China and packaged in a compact format suitable for handheld play.[7] This launch capitalized on the enduring fame of the Rubik's Cube, which had sold over 100 million units by the mid-1980s, positioning Magic as a fresh challenge in the Rubik's brand lineup.[8] The commercial rollout featured an aggressive international marketing strategy, including a high-budget sales campaign across Europe and North America, with television commercials showcasing Rubik himself demonstrating the puzzle alongside celebrity endorsements, such as wrestler "Macho Man" Randy Savage in a notable U.S. ad.[9] Each unit bore Rubik's signature, enhancing authenticity and brand loyalty. Over its commercial lifespan, Rubik's Magic achieved significant success, selling more than 14 million units globally and contributing to the Rubik's portfolio during the peak puzzle boom of the 1980s.[4] Despite its strong initial reception, popularity began to decline by the late 1980s amid market saturation from numerous Rubik's variants and competing mechanical puzzles. The puzzle's novelty waned as consumer interest shifted, though it remained a staple in toy collections and briefly revived interest in folding-style challenges. In Hungary, it was initially released under the name "Karikavarázs" ("Ring Magic").[6]Puzzle Design
Components and Construction
The Rubik's Magic puzzle is constructed from eight rigid, square plate-like tiles arranged in a 2×4 rectangular formation.[5][1] These tiles are made of synthetic plastic material, resulting in a compact overall size suitable for portability when folded.[5] The tiles feature flat upper and lower surfaces, straight lateral sides that may be beveled for smooth rotation, and diagonal grooves etched into both surfaces at 45-degree angles to the edges.[5] The tiles are interconnected by eight separate closed loops of flexible plastic wire or string running through the diagonal grooves.[5][10] These loops are not fixed to the tiles but lie within the grooves, allowing the tiles to fold and rotate relative to each other by 90 degrees in two perpendicular directions, similar to the motion of a Jacob's ladder.[5][1] The grooves are designed with a depth that keeps the loops flush with or below the tile surfaces, ensuring smooth articulation without protrusion.[5] In the original 1986 version, the tiles are black with printed rainbow-colored ring segments, where each tile displays portions of incomplete rings that span multiple tiles.[1] A 1997 re-release featured red tiles accented with gold rings, maintaining the same structural design but updating the color scheme for visual appeal.[1] These markings consist of half-ring or segment patterns on individual tiles, enabling alignment configurations when manipulated.[1]Objective and Solved States
The primary objective of Rubik's Magic is to fold the initial 2×4 grid of eight interconnected tiles into a heart-shaped, six-cornered polygon, thereby visually interconnecting the three rings illustrated on the reverse side of the tiles while also unscrambling the picture on the opposite side into a coherent pattern.[11][12] This transformation links the rings, which start as separate and incomplete segments across the tiles, into a unified chain through precise folding and manipulation.[12] In the solved state, all ring segments on the tiles align seamlessly to form three complete, interlocked circles without overlaps or gaps, creating the illusion of physically linked rings.[11] The tiles, connected by thin wires that allow hinging at the edges, enable this reconfiguration while maintaining structural integrity.[13] Secondary objectives expand on the primary goal by challenging solvers to form a cube-like 3D shape from the heart configuration or other patterns, such as an 8-pointed star where the rings align correctly.[11] These variations highlight the puzzle's capacity for diverse geometric assemblies beyond the standard heart.[12] The puzzle admits several distinct ways to achieve the heart shape with linked rings, underscoring the non-unique nature of solving paths and encouraging exploration of varied folding sequences.[14]Solving Methods
Basic Techniques
The basic techniques for solving Rubik's Magic begin with restoring the puzzle to its initial flat, scrambled 2x4 rectangular configuration from any tangled state, ensuring all eight square panels are aligned in two rows of four without twisted wires or overlapping tiles. This setup allows identification of key tiles, such as those with arc patterns indicating ring starts and ends—these arcs guide the formation of the three interlocking rings that form the puzzle's solved heart-shaped envelope. Practitioners should handle the puzzle gently to avoid straining the embedded wire loops that connect the panels.[15] To form partial rings, start by folding the edges inward using fundamental moves: flip individual panels or groups by rotating them 180 degrees over adjacent ones, fold rows together by pushing them flat with touching sides, and open by pulling rows apart to create three-dimensional shapes that reposition wires. A step-by-step guide involves first positioning key arc tiles—for instance, moving the signature tile (on the unlinked side) to the lower-right corner via corded-corner folds, then aligning adjacent text tiles along the bottom row. Next, perform a series of rotations: fold the right two columns inward, roll the top row halfway over the bottom to interconnect partial loops, and repeat the sequence up to three times until the middle arcs align for ring closure. On the linked side, position the triple-arc tile (the only panel with three arcs) in the upper-left middle position, rotate it 90 degrees using a similar inward fold, and adjust neighbors by half-rolling to link the outer rings. These steps prioritize layer-by-layer interconnection, building from isolated loops to the full heart-shaped goal with three interlocked rings.[16][15] Common beginner patterns include the "accordion" or zig-zag fold, which manipulates wire loops without tangling: start with the flat rectangle, fold the panels in a alternating up-down pattern (like compressing an accordion) to form a compact block, then peel and turn one end tile over while folding the opposite end up to shift loops evenly. This pattern is useful for unscrambling partial rings and can be combined with the loop shift—folding into a 1x8 strip, pulling it into a loop, and refolding flat—to cycle arcs without inverting the puzzle. Another essential is the roll transform: fold the outer columns inward, then roll the top over the bottom by one panel to align middles for interconnection.[17][13] Troubleshooting common issues focuses on preventing wire jams and invalid folds: always return to a flat 2x4 or 3x3 notched shape if resistance occurs, as these are the only valid configurations per the puzzle's mechanical constraints; if wires jam during folding, gently open the structure and retry the move in the opposite direction or with the alternate side facing up. For invalid folds that prevent ring closure, verify arc alignments before proceeding—mispositioned key tiles often cause this—and alternate between reverse folds (flipping ends up to form a square) and wallet stacks (folding into a layered stack) to reset without forcing hinges, which could damage the wires.[16][15]Advanced Strategies
Experienced solvers of Rubik's Magic employ pattern recognition to identify specific configurations of the tiles, such as those maintaining the sequential order of squares 1 to 8, enabling shortcut folds that transform the puzzle more efficiently than basic methods. By recognizing these patterns, solvers can apply targeted transformation sequences, like interchanging rows or turning individual squares, to reduce the number of steps needed to link the three rings into the heart shape. These sequences are reversible and of order 2, allowing for quick experimentation and adjustment during solving.[11] Speed techniques in advanced solving emphasize pre-planning the alignment of the rings and tiles to minimize hesitation during folds and twists. Solvers often use the advanced method, which incorporates twisting individual tiles by 90 degrees alongside folding, to achieve faster times compared to twist-free approaches. This method facilitates rapid manipulations, with top solvers reaching sub-1-second solves through consistent execution of the core folding sequence.[18][11] Minimal move solutions prioritize the shortest paths to the solved heart state, utilizing transformation sequences such as a mirrored version of standard folds to interconnect the rings with fewer operations. For instance, combining repositioning of key tiles with sequences like B and C1 yields an efficient path to the linked rings configuration, often requiring only a handful of folds and turns. Commutator-like sequences, where a setup move is followed by a conjugate action to isolate effects on specific tiles, further optimize these paths by temporarily altering and restoring adjacent elements.[11] Practice tips for advanced proficiency include drilling specific scrambled states to build muscle memory for the folding and twisting motions. Repeatedly solving from common "challenging" configurations, such as partially linked rings or misaligned chains, helps develop intuition for pattern shortcuts and smooth finger movements, enabling consistent sub-5-second solves over time. Focusing on the final folds, where errors are common, ensures reliability before pushing for speed improvements.[18]Mathematical Analysis
State Space Exploration
The state space of Rubik's Magic, a puzzle comprising eight interconnected tiles forming a closed chain via embedded wire loops, encompasses a vast array of theoretical configurations constrained by the puzzle's mechanical design. Analysis reveals 1,351 spatial configuration classes for the puzzle, of which only two are planar, derived from the permutations of tile connections and wrappings around the loops, assuming the mechanism's constraints.[19] However, practical limitations imposed by the physical folding of tiles—such as the inability to pass tiles through each other or excessive twisting of wires—reduce the number of achievable states, with 16 reachable flat rectangular configurations identified.[1][20] A key constraint in this state space arises from parity considerations related to fold counts and wire orientations. The puzzle's moves, which involve folding tiles along diagonal hinges, exhibit non-commutativity, meaning the sequence of folds affects the final configuration in a path-dependent manner; for instance, folding one tile before another may lock wires differently than the reverse order. Additionally, parity issues manifest in the even or odd number of folds impacting ring linkages: configurations requiring an odd net turn count for subsets of tiles (e.g., unequal right and left turns between odd- and even-numbered tiles) become infeasible, as the wire loops must maintain a balanced wrap of ±2 to close properly. Flat configurations must also have an even total enclosed hole area.[1] Enumeration of reachable states employs basic graph theory, modeling tiles as nodes in a cycle graph and folds as edges representing possible transformations between positions. Manual counting, supplemented by computational enumeration of wrap types (e.g., +2, -2, or 0 wraps per connection), systematically maps the configuration graph, identifying valid paths from the initial rectangular state. This approach confirms that only a subset of the theoretical shapes adheres to the puzzle's invariants, such as even total enclosed area for looped configurations.[20][19] Unsolvable positions typically involve impossible wire crossings or entanglements that would require the loops to intersect themselves in 3D space, effectively locking the puzzle without violating the tile order. For example, a configuration demanding a tile to pass through a closed wire loop without unfolding the chain is unreachable, as it contravenes the fixed connectivity of the embedded strings. Such states highlight the puzzle's combinatorial restrictions, distinguishing it from freer chain puzzles by enforcing strict topological invariants.[20]Algorithm Development
The development of algorithms for Rubik's Magic has focused on computational methods to identify optimal folding sequences in its state graph, where nodes represent tile configurations and edges correspond to valid folds along the interconnecting filaments. The equivalent of God's algorithm for this puzzle employs breadth-first search (BFS) to determine the shortest path from any reachable scrambled state to the solved configuration. Due to the compact state space, solutions are generally short.[1] Early software simulations, such as those created by Jaap Scherphuis in the late 1990s, modeled the puzzle's folding mechanics by simulating tile hinges and filament constraints to enumerate flat and 3D configurations, facilitating scramble generation and state validation.[1] Modern tools build on this foundation, using graph-based representations to generate random solvable positions for practice or analysis while avoiding unreachable states.[21] The computational complexity of solving Rubik's Magic is polynomial-time for the standard 2×4 grid, owing to its small state space of reachable configurations, which allows exhaustive exploration via BFS in seconds on standard hardware.[18] However, generalizing the problem to larger grids introduces NP-hard aspects, as determining whether a hinged polyomino chain can fold into a target shape is NP-complete even for simple colored variants.[22] Historically, 1980s algorithms relied on manual sequences derived from geometric intuition, such as the rectangle, loop, and star transforms outlined in the original patent and guides, which typically required 10-15 folds for standard solves. By the 2000s, computer-aided reductions—leveraging symmetry and invariants like linking numbers—enabled systematic optimization, reducing average solution lengths and supporting automated solvers for variants.Variants and Editions
Master Edition
The Rubik's Magic: Master Edition, released in 1987 by Matchbox, features 12 silver-colored tiles arranged in a 2×6 rectangular formation, interconnected by nylon wires to facilitate folding movements.[23] This design expands on the original puzzle's 2×4 layout by adding four more tiles and corresponding wiring, allowing for greater flexibility in reconfiguration while maintaining the core hinge-based mechanics where tiles pivot along the wires' paths.[1] The primary objective is to manipulate the tiles from an initial state displaying five interlinked rings on a silver background into a distinctive W-shaped configuration where the five rings appear unlinked and separated.[23] Unlike the original Rubik's Magic, which focuses on linking rings into a heart-like form, the Master Edition emphasizes disentangling the rings through strategic folds. The mechanics are generally simpler due to the additional hinges, enabling easier wire management and short solution paths, though the increased scale introduces risks of temporary tangles during manipulation.[23] Despite its relative ease compared to the standard version, the Master Edition's larger size permits more complex three-dimensional folds, enhancing spatial challenges while rewarding precise control to avoid wire entanglements that could complicate progress.[1] This variant's design promotes exploration of 22 possible planar shapes, each with multiple tile permutations, fostering deeper engagement with the puzzle's folding dynamics.[18]Re-releases and Custom Versions
In 1987, Matchbox also released the Mini Magic, a simpler variant with four smaller 2×2 tiles designed for easier challenges.[24] In 1996, Oddzon re-released Rubik's Magic with updated aesthetics, featuring yellow rings on a red background while retaining the original 2×4 tile mechanics and eight interconnected panels.[1] A themed edition, the Simpsons double-sided puzzle, was released in 2001, featuring images from the animated series on both sides for dual challenges.[3] Unlicensed variants emerged, particularly from Asian manufacturers, including 2×8 tile versions such as the "Magic Balls" produced by ST Toys, which used smaller tiles with spherical designs instead of rings for a more compact form.[25] Another notable edition, the "Create the Cube," involved eight colored tiles configured to form a 2×2×2 cube shape in the solved state, building on the core folding mechanism of the original puzzle.[26] Modern custom versions have proliferated through hobbyist communities, with 3D-printed expansions extending the design to larger grids such as 2×12 tiles for increased complexity in ring-linking challenges. Online platforms offer downloadable designs for even larger grids, allowing users to fabricate personalized puzzles using accessible 3D printing technology.[27] As of November 2025, Rubik's Magic remains available primarily through vintage sales on platforms like eBay, where original and re-release editions fetch collector prices, with no major official releases occurring since the 1990s.[28]Competitive Solving
Official Events and Regulations
The competitive solving of Rubik's Magic became an official event under the World Cube Association (WCA) with its inclusion in the World Rubik's Games Championship 2003, held in Toronto, Canada.[29] This marked the puzzle's integration into organized twisty puzzle competitions, alongside staples like the 3x3x3 Rubik's Cube, and it remained part of WCA-sanctioned tournaments for the next decade. The event emphasized speed in transforming the puzzle from its initial flat configuration to the solved heart shape, attracting participants interested in folding puzzles. Regulations for Rubik's Magic followed the WCA's general speed-solving framework in Article A, with puzzle-specific adaptations in Article G (or H in earlier versions). The puzzle started in a standard flat state with rings unlinked and the reverse-side picture unassembled, serving as the consistent "scrambled" position for every attempt to ensure fairness and avoid complex randomization.[30] Solvers aimed to fold the tiles into the heart-like shape, linking the rings and aligning the picture tiles correctly, with the final configuration required to lie flat and maintain tile angles of at least 135 degrees relative to adjacent pieces.[30] There was no formal inspection phase, as the starting state was uniform and visible; timing began when the competitor initiated folds and ended upon judge verification of the solved state, with penalties for minor angle deviations (+2 seconds) or major errors (DNF).[31] Event formats mirrored other WCA speed events, featuring preliminary rounds with multiple attempts and finals determining rankings via the average of 5 solves (Ao5), while best single times were also recorded for official recognition.[32] To aid visibility and stability during solves, competitors often used provided stands or mats to display the puzzle, allowing judges and spectators clear observation without interference. The WCA discontinued Rubik's Magic as an official event after December 31, 2012, with removal effective January 1, 2013, citing challenges in consistent global judging due to subjective start/stop timing and the event's emphasis on physical dexterity over analytical solving, compounded by low participation compared to core puzzles.[33] Post-discontinuation, competitive interest persisted in unofficial speedsolving communities, where informal tournaments maintained similar formats without WCA oversight.[34]World Records and Achievements
The World Cube Association (WCA) recognized Rubik's Magic as an official competitive event from 2003 until 2012, during which time records were set and tracked for both single solves and averages of five attempts. The current world record for a single solve of the original 8-panel Rubik's Magic stands at 0.69 seconds, achieved by Yuxuan Wang of China at the Beijing Spring 2011 competition.[35] Similarly, the world record average of five is 0.76 seconds, also set by Yuxuan Wang at the Beijing Summer Open 2011, with individual solves of 0.72, 0.77, 0.77, and 0.75 seconds (one DNF).[35] For the Master Edition (12-panel variant), which was likewise an official WCA event until 2012, the single-solve world record is 1.66 seconds by Yuxuan Wang at the Tianjin Winter Open 2012.[36] The average-of-five record is 1.75 seconds, held by Ernie Pulchny of the United States at the 2011 US Nationals, based on solves of 1.78, 1.71, 1.77, and 1.71 seconds (one 3.08-second solve).[36] Historical rankings from WCA data highlight dominant performers such as Yuxuan Wang, who set multiple records across both variants, alongside Ernie Pulchny and Mátyás Kuti. No official records have been updated since 2012, following the event's removal from the WCA regulations; while community discussions mention unverified unofficial solves under 0.5 seconds for the original puzzle, these lack formal validation under standardized rules. A key milestone was the first sub-1-second single solve, accomplished by Mátyás Kuti of Hungary in 0.86 seconds at the Belgian Open 2007.[37] The following tables summarize the all-time top five single-solve performances for each variant, based on WCA-sanctioned results: Original Rubik's Magic Top 5 Singles (historical bests)| Rank | Time | Solver | Country | Competition | Year |
