Yosumin! LIVE and Yosumin! are the latest renditions of the innovative puzzle game Yosumin, previously released only for the Japanese market. Players must give a colorful panel of yosumin a sweeping glance, locate a square or rectangle with four corners of the same color and click on the corresponding yosumin to make them disappear. Enjoy an engaging puzzle-game experience just by following these simple rules.
While the basic rules and system remain the same, the latest releases include unique modes specific to each platform version. In the Xbox LIVE Arcade for Xbox 360 version, players can compete against the computer or with friends, and when online, with other players around the world. In the Windows PC version, players can collect pieces of stained glass as they clear the puzzles in the "Yosumin! Adventure mode," enjoying the best of both the puzzle and item-collecting experiences.
