Hexic HD

Included free with every Xbox 360 System, this Xbox Live Arcade puzzle game is designed by Alexey Pajitnov, the internationally-known creator of Tetris. You will spend your time rotating groups of different colored hexagons, attempting to group them together and wipe them from the board. Special blocks add points in the equation. Bombs make an appearance, and if you don't clear them in a specified number of turns, the the game is over. This makes for a tense and entertaining experience. Even the music changes to a gripping song ala "Who Wants To Be A Millionaire?" when a bomb drops in.
