FREE TO START The first two worlds and the Daily Flip are free. One purchase unlocks everything else, forever: six more worlds, every secret, the full One-Shot ladder and the Sandbox. No ads, no tracking, no account. Every tile holds a number. Play one of yours onto it: the values add, the tile flips, and every lower-numbered neighbor topples after it, domino-chaining across the board. The catch: past 9, numbers roll over. 6 + 6 = 2. The goal: clear it all with a handful of numbers. That one rule hides the depth. Greed has a price, nines are fortresses, zeros are scalpels. And one perfect placement can flip the whole board in a single, glorious GRAND CASCADE. A JOURNEY OF EIGHT WORLDS 96 hand-calibrated levels teach the game by play, never by text. Stones block, seals lock, ice cracks, bombs level everything beside them, traps must never flip, wormholes carry your cascade across the board, and shifter tiles grow with every move you make. Collect a world's gems and its secret level appears. EVERY LEVEL CERTIFIED FAIR Each puzzle ships machine-verified: always solvable, par always exact, never cheap. Unlimited undo and a solver-powered hint are built in. Thinky, never punishing. THE DAILY FLIP One board, the whole world, every day. Keep your streak (one automatic repair a month, because life happens), and share your result without spoilers. FLOURISHES, NOT STARS Every level carries one optional master-goal: clear it in a single placement, never roll over, end on a 9. No grinding, no ratings, just elegance. MADE LIKE A TOY Chunky ceramic tiles that flip with real weight, synthesized marimba cascades that climb as your chain grows, haptics choreographed to every topple, Day and Night themes, Home Screen widgets for your streak, and in the large sizes today's Daily board and your numbers (extra-large on iOS 27). PRIVATE BY DESIGN No ads, no tracking, no account. Playable offline.
