This head-to-head puzzle game tasks players with clearing their grid of falling pieces, known as puyos, by arranging four or more of the same colour into straight lines or other recognised patterns. Its competitive element comes from the fact that clearing puyos sends random filler pieces to the opponent’s grid. Larger clears generate more filler, increasing the pressure on the opposing player. A round is won by filling the opponent’s grid to the top. The game also includes a light narrative framework for solo or multiplayer play.
