An expansion for Tixel, which consists of 4 extra pieces for each player. Expansion pieces are different from regular pieces in that they are completely square-shaped instead of being hollow on one side. For each expansion piece used, remove one tixel piece from the game. The expansion pieces can be used to add variety to games, but they can also be used to handicap a stronger player. Simply give the stronger player more expansion pieces compared to the weaker player. With two expansion sets, the original Tix game can also be played on the Tixels board.
