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.
BUILD AN ENGINE
• 60 modifiers that twist the rules, multiply doubles, reward long chains, pay interest on your savings, or explode your score with stacking ×MULT
• Consumables and vouchers for one-shot saves and permanent upgrades
• Enhance, duplicate, and trash tiles to sculpt your deck
SURVIVE THE CAMPAIGN
• 12 antes, each guarded by a unique boss with its own rule-bending power
• The Squeeze shrinks your hand. The Eclipse turns out the lights. The Hourglass never stops ticking.
• Reach the finale and face Dominus Ossium. A 140-second clock that grows stronger the closer you get to winning
PAY THE RENT
• Your modifier engine isn't free, every blind charges upkeep
• Bank Bits, earn interest, and don't go bankrupt before the boss
FREE, FAIRLY
The full campaign is free. No lives, no timers, no paywalls. One optional purchase removes ads forever.
Good luck making rent.
