Glover is a 1998 puzzle-platformer developed by Interactive Studios and published by Hasbro Interactive for the Nintendo 64 and Windows in 1998, and for the PlayStation in 1999 (branded under Hasbro Interactive's Atari Interactive label). The game follows a magical, four-fingered glove named Glover in his quest to restore the Crystal Kingdom by retrieving crystals that were lost.

The Nintendo 64 and Windows versions received generally positive reviews while the PlayStation version garnered negative reviews. A sequel titled Glover 2 was planned, but eventually cancelled. A second updated Windows port was released in 2022 and a port for Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S was released on February 27, 2025.

Players control a glove named Glover. The main objective is to maneuver the ball toward the goal in each stage. Once all three stages and the boss stage are cleared, a crystal ball can be restored back to the castle. There are six worlds, each containing three stages, a boss stage, and a bonus stage accessed by collecting all the Garib cards in a given world. When Glover is in contact with the ball, he can roll, bounce, throw, slap, dribble, walk on top of the ball, and use it as a trampoline. Without the ball, Glover can do both regular and double jumps, cartwheel, fist slam, locate the ball and garibs, and grab the ball. While walking on the ball, the controls are reversed. On easy difficulty, walking on the ball is automatic while moving the ball across water. However, bonus stages are unavailable.

The ball can also be magically transformed into one of four forms: rubber ball, ballbearing, bowling ball, and the ball's original crystal form. With a cheat code, the ball can be transformed into a power (high-bounce or super) ball. The rubber form gives the greatest amount of abilities for the ball. It can easily be bounced, slapped, thrown, and even float on water. The bowling ball form allows the ball to not break easily, sink in deep water, and kill enemies by slapping it. The ballbearing form gives precise control over the ball, can be used to throw and slap the ball more carefully and is also magnetic. The crystal form floats on water and is fragile, but gives double points for each obtained Garib. The power ball can bounce higher and be slapped and thrown farther than other forms. Throughout the stages, there are magic potions that help Glover by giving him power-ups for a certain amount of time.

If the ball gets destroyed or Glover loses all three hearts, Glover loses one life and must start from the beginning of the stage or from the last checkpoint.

The story takes place in a fictional land known as the Crystal Kingdom, where a wizard rules from his Crystal Castle, which is surrounded by six portals leading into other worlds, including the lost city of Atlantis, a circus park, a pirate's domain, a horror-themed fortress, a prehistoric era, and outer space. The life force of the kingdom is maintained by seven magical crystals that rest atop the spires of Crystal Castle. The wizard is accompanied by the magical, sentient gloves Glover and Glovel, who assist him in creating strange potions and spells.

One day, the wizard accidentally mixes the wrong batch of potions in his cauldron, causing a large explosion that turns the wizard into a statue, sends him falling down the tower, and sends his gloves flying. The left glove, Glovel, lands in the cauldron while the right glove, Glover, flies out the window and lands onto the ground outside the castle. The explosion also shakes the crystals from the spires, causing the land to become dark and foreboding. Before they could shatter upon impact, Glover quickly casts magic to turn the crystals into rubber balls. One of the balls remains in the kingdom while the other six bounce into each of the portals. Glover realizes that to bring the wizard back to life and restore the kingdom's beauty, he must enter these worlds, find the crystals within them and bring them back to the castle. However, Glovel was corrupted by the cauldron's chemicals and becomes "Cross-Stitch", a malevolent trickster who is determined to destroy Glover and rule the Crystal Kingdom for himself.

Glover traverses from realm to realm and must protect the rubber balls at all costs while bring them back home. As he does, Cross-Stitch attempts to thwart him by setting traps and creating monsters, but Glover is able to overcome these obstacles with his magical skills and retrieve the crystals. He is also aided by a living hat named Mr. Tip, who offers hints during Glover's quest. The Crystal Kingdom is gradually restored to its former state with each crystal returned to the castle. In the final realm, Glover fights Cross-Stitch in a giant robot fight and emerges victorious, sending Cross-Stitch flying.
