The game involves players manipulating a grid of "yosumin", or tiles to make color matches and eliminate a certain number before time runs out.

[1] The player has a target goal of the number of rectangles with yosumin of specific types that must be removed, and has a time limit.

Creating rectangles can remove time from the opponent's timer, and specific yosumin which are selected before the game begins perform other moves such as stunning the opposing player.

[6] It was shown to be an enhanced port of the original Yosumin browser game[7] released by Square Enix on the @nifty network.

This was confirmed to be part of publisher Square Enix's effort to expand their fan base internationally and across more types of players and genres, including more casual games.

[16] IGN liked the PC version of the game, noting the loss of the Xbox Live Arcade multi-player but complimenting the expanded single player mode.
