Rot: Numbers Decay

Numbers rot. Count fast.

Rot is a real-time number puzzle where the board is alive. Every few seconds the numbers grow and decay — fresh green turns to creeping brown mold. Your job: merge adjacent cells that add up to exactly 10 and burn them away before a cell hits ten and bursts. Let too many burst and the board rots over — game over.

Easy to pick up, hard to put down.

- Select connected groups of neighboring cells - Hit a sum of exactly 10 — burn it for points - Don't let numbers reach 10 and rot the board

WAVES OF TENSION The game breathes: calm stretches build into peaks of panic, then ease off again. It heats up over time, but always lets you catch your breath.

ABILITIES Earn charges with clean burns and spend them wisely: - Freeze — stops the growth for a few seconds - Wind — burns an entire row - ×2 — doubles the points of your next burn - Compost — turns selected cells back into fresh sprouts

RISK AND GREED - Ripeness — overripe cells score double, but they're about to burst - Combos — back-to-back burns stack a multiplier up to ×5 - Quarantine — long-press to seal off a dangerous cell

HEAL THE WORLD Every run's score fills a bank, and you spend it healing the world of rot — region by region on a living map. Stay away too long and the world starts creeping back. Come back and keep it alive.
