Switchball

The game puts the player in the role of a ball, which is guided through various courses suspended in mid-air in five different environments: Skyworld, Iceworld, Caveworld, Cloudworld and Lavaworld, each one having six courses.

Each course contains multiple puzzles for the player to solve. The ball is used to push around objects and activate switches, among other things. Using PhysX as its core physics engine, the game features many physics-based puzzles. Obstacles, traps, and other objects are common throughout the game. Some common objects include boxes, switches, fans, cannons, magnets, and rails.

Originally called Crazy Ball, the game won "Best PC Game" during the 2005 Swedish Game Awards and was a finalist in the "Technical Excellence Class" during the 2006 Independent Games Festival. Crazy Ball was developed in five months.

The gameplay is similar to Atari's 2004 game Ballance, but features worlds instead of levels.

GamesRadar awarded the PC version of Switchball 8 out of 10, praising the AGEIA physics engine, commenting that "the rolling and bumping and knocking and flinging are all exquisitely well done. And physics, the best thing to happen to games since explosive barrels, has a way of making you care". Team Xbox awarded the Xbox 360 version a 9.4 of 10 and called Switchball as one of the best puzzle games for Xbox Live Arcade. IGN commended the AGEIA physics engine, calling it a major star of Switchball.

CVG criticized the difficulty of the later level puzzles in its review of the PC version: "It doesn't run out of brains, but in later chapters it does succumb to that misguided urge to crank up the pressure. This goes badly. Switchball is a thoughtful puzzle game, but neither its camera nor controls are up to the dexterity-driven tasks it sets here".
