Cat Laundry

Cat Laundry とは？

Cat Laundry is a free 4×4 browser strategy duel about cats in washing machines. Each 8-second turn, you sacrifice one cat: it switches to the enemy color while a delayed diagonal wave recolors the board for you. Close squares, diamonds, or crosses to score, or move quickly to interrupt an opponent’s wave before it finishes. Separate shapes score together; overlapping ones keep only the highest value. Matches last 4–5 minutes. Play Hard AI without an account or challenge another player online.
