Construx is a brand of plastic building toys introduced by Fisher-Price in 1983. Unlike other building toys such as Lego, Construx feature beam-like pieces of varying lengths that snapped on to cubical connector knots in order to build large shapes. These are relatively secure even though no nuts or bolts were used. Panels allowed assembly of flat surfaces. Hinges, motors, wheels, and other movable parts expand the number of different shapes that can be built, and make moving creations possible. Construx was discontinued in 1988, briefly revived by Mattel in 1997, and then discontinued again. Mattel resurrected the Construx name as Mega Construx in 2017 (see Mega Bloks).

For a short time near the end of the Fisher Price run, a version targeted at younger children was released called Basix Construx. It used bright primary colors and did not contain the more complex pieces such as axles and pulleys. This version as well as the other boxes released in the 1997 revival included several new pieces.

A brief revival occurred in 1996, when reintroduced eight new Construx sets targeted at children ages 8 and older, including builder kits and themed options like Rugged Racers; however, this effort ended by 1997. The brand's inactivity coincided with 's acquisition of in 2014 for $460 million, a company whose Mega Bloks line had faced ongoing legal disputes with over interlocking brick designs, though these did not directly involve the original Construx system. During the extended hiatus from 1989 to 2016, official production halted entirely, but enthusiast communities sustained interest through custom builds and trading of vintage parts on secondary markets such as . In 2017, announced the revival of the Construx name under the umbrella as Mega Construx, rebranding existing Mega Bloks construction elements—combining bricks and beams—to evoke the original system's modular play while incorporating micro-action figures for enhanced storytelling. This relaunch targeted ages 4 and up, capitalizing on nostalgia for the toy while leveraging popular licensed intellectual properties, including Halo, to attract both new builders and adult collectors. In 2025, introduced Mattel Brick Shop, a new direct-to-consumer line of advanced collector building sets available through Mattel Creations, further evolving the brand's offerings for adult enthusiasts.

Design and components

Core building system

The core building system of the original Construx line consists of perforated beams as the primary structural elements, available in lengths ranging from short segments to longer spans equivalent to 1 through 8 units (with each unit approximating 0.5 inches based on peg spacing). These beams, molded from durable ABS , feature evenly spaced holes along their length for secure attachment at multiple points and angles, enabling complex assemblies. Common colors include grey for the initial Imagination Series, white for the Space Series, and black for later lines like the Alien Series, allowing builders to create visually distinct frameworks. Connectors form the system's hubs, with types such as multi-peg nuts (typically blue in early sets), micro-clips for precise attachments, and hinges for articulated joints supporting 90-degree, 180-degree, or flexible connections. These components interlock to provide inherent stability, facilitating the construction of upright structures that withstand typical play forces without tools or adhesives. The assembly process promotes intuitive, trial-and-error , as beams click firmly into connector slots without requiring additional hardware, fostering experimentation in load distribution and balance. is prioritized through rounded edges on all pieces to minimize risk, combined with non-toxic ABS plastic that meets 1980s-era ASTM F963 standards for toy materials, ensuring no harmful emissions or sharp hazards. Unlike solid-brick systems like , Construx emphasizes open skeletal frames via its beam-and-connector design, which excels in replicating lightweight yet robust forms such as and bridges.

Specialized pieces and accessories

In addition to the core structural elements like beams and connectors, Construx sets incorporated specialized action accessories to enable more dynamic and functional constructions. Introduced in 1985 as part of the Imagination Series expansion, these included wheels, axles, pulleys, and turntables, which allowed builders to create moving , cranes, and rotating mechanisms. For instance, black wheels with integrated axles measured approximately 15/16 inches in diameter and could be attached via connector bars for stable rolling motion. Take-apart figures represented another key category of specialized pieces, designed for customization and integration with beam-based builds. These humanoid and alien models featured jointed hips, shoulders, and movable heads, with interchangeable limbs that clipped directly onto beams or other components via peg connectors. Humanoid examples included a 3-inch-tall green soldier figure from the Military Series, comprising about 12 pieces such as a helmet, torso, arms, legs, and accessories like a mouthpiece. Alien variants, such as the 3-1/8-inch green alien with a gold shell head and triangular eyes or the purple alien with a claw hand, added thematic variety and encouraged mix-and-match play across series. These figures, first appearing in sets like the 1984 Space Series #583 Spacecraft Assortment, enhanced role-playing by allowing attachment to vehicles or structures. Themed panels provided aesthetic and functional enhancements, serving as walls, roofs, or shields in constructions. These were often transparent or printed sheets tailored to specific series; for example, the Alien Series featured tinted panels, including clear blue variants measuring 4-1/4 inches square for use in space-themed builds like the #6460 Lunar Command Station. In the Military Series, tan panels with green patterns (2 inches square) were common, appearing in sets such as #6310 Military Vehicles Assortment to simulate or vehicle siding. Some panels had angled corners for better fitting in irregular designs, promoting versatile enclosure options. Motorized components further expanded interactivity, debuting in 1985 with battery-powered units in the Imagination Series. The primary example was the #6450 , a 50-piece set including a black motor unit (requiring 2 C-size batteries) that drove gears, belts, and other mechanisms for automated movement in builds like rotating platforms or propelled vehicles. Additional elements, such as a light pack powered by 2 D- or AA-size batteries, illuminated structures, while the motor's design supported via wiring for varied play scenarios. These units emphasized safe, low-speed operation suitable for children. A hallmark of the Construx system was its full compatibility, with all specialized pieces interchangeable across themed series from the original 1983 launch through 1988.
