Hexic

Hexic is a tile-matching puzzle video game where the player tries to rotate hexagonal tiles to create certain patterns. The game was designed by Alexey Pajitnov, best known as the creator of Tetris. It was developed by Carbonated Games and is available online as part of MSN Games, as well as a downloadable deluxe edition. A variation of the game called Hexic HD comes preinstalled on all Xbox 360 hard drives; it was previously only available by calling Microsoft's Service Center but is now available on the Xbox Marketplace as a free download.
