## What is 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.

PLAY YOUR WAY
• Endless — infinite, ever-harder grids at Easy, Medium, or Hard
• Daily — one shared challenge a day
• Duel & Online — go head-to-head with a friend or a random player over Game Center, same puzzles, live scores (one-time unlock)

MADE TO FEEL GREAT
Satisfying cascade effects, unlockable styles, colors, and relaxing music tracks, tactile haptics, and a clean, focused board. Turn on Unlimited Time for relaxed solving, or race the clock for big speed bonuses.

Free to play. No ads. Unlock live multiplayer once and it's yours forever.
