Gameplay

Sudoku, minus the numbers.

The same rules you know, read through color and shape instead of digits. Every palette pairs each color with a symbol, so the board stays readable.

01 / RULES

No repeated colors

Each row, column and 3×3 block must hold all nine colors exactly once. Same logic as classic Sudoku, faster to scan.

02 / NOTES

Notes and hints

Pencil in candidate colors on undecided cells, undo a move, or ask for a hint when you hit a wall.

03 / DAILY

A new puzzle every day

The Daily Challenge gives everyone the same fresh board every 24 hours. Keep your streak going.

04 / LIVES

Three lives per game

Every wrong color costs a life. Run out and the game ends, unless you watch an optional video for one more.

05 / PALETTES

Seven palettes to unlock

Earn points by finishing puzzles and spend them on Neon Cyberpunk, Pastel Dream, Deep Ocean, Retro Arcade and more.

06 / PRIVATE

No account needed

Progress, streaks and unlocked palettes stay on your device. Ads keep the game free, and videos play only when you choose.
