A single player domino roguelike. Chain tiles, stack score boosting modifiers, and beat the rent before it buries you. 12 antes, 12 bosses, one perfect run.

Dominoes, but a roguelike. Chain tiles for PIPS × MULT, stack game-breaking modifiers, and beat the rent before the boss comes knocking. OSSA: DOMINOES is a single-player score-attack roguelike built on real domino rules. Every run: draw a hand, build chains off the dealer tile, and push your score past the target — then decide what to buy, what to sell, and what you can afford to keep.
