It’s just you and a board of colorful shapes in this fast-paced puzzle game. You control an arrow inside a four-by-four grid in the middle of a larger playfield. Along each of the outer edges, objects appear over time (indicated by a flashing outline). If a new shape is set to appear where one already is, it will push its predecessor along the column/ row toward the center. Your job is to eliminate them by matching colors before they enter your grid.
