Cascadoku

Cascadoku is Sudoku with a spark. Place a correct number and watch it detonate — the cells it forces snap into place in a chain reaction that scores bigger the longer it runs. It's the logic game you know, rebuilt as a fast, replayable run. CHAIN REACTIONS Every correct placement can trigger a cascade down its row and column. Short chains feel good. Long ones feel incredible — and the combo multiplier rewards you for setting them up. DRAFT YOUR POWERS Clear a grid and draft a power that lasts the whole run. Stack Overclock for bigger cascades, Domino to double every chained cell, Jackpot for huge end-of-grid bonuses, and more. No two runs play the same. A NEW PUZZLE EVERY DAY The Daily Challenge gives everyone the same seeded run. Build a streak, climb the Game Center leaderboard, and see how your score stacks up.
