Star Stacker is another take on falling block puzzle games and comparable to Tetris Attack. Blocks fall in pairs, containing different combinations of stars and one of the three animal friends. The object is to line up Star Blocks and sandwich them between two matching animal friends, racking up combos and clearing as many stars as possible. Players can partake in an endless Challenge mode, race the clock in Time Attack, or link up with a buddy and play head-to-head.
