The rules of Blokus are simple: Each player places his/her pieces on the board in turn, ensuring that pieces of the same color touch at one or more corners, but never along the sides. The objective is to strategize and place as many pieces as you can before your opponent/s beats you to it. Based on the same basic rules and intuitive gameplay that made the board game a success, Blokus Portable allows up to 16 people to play in ad hoc wireless mode, or up to three friends to play simultaneously using one Universal Media Disc (UMD) in the ad hoc game sharing mode. Blokus Portable combines the original 4-player Blokus plus the 2-player Blokus Travel/Duo, while letting players customize their own character and unlock 18 additional characters from the Steambot Chronicles series.
