Sudoku: Color

Real-time Multiplayer is here! Challenge a friend or get matched with a stranger. Fresh Daily Puzzles with unique twists keep your mind sharp every day.

Sudoku — but make it colorful.

Sudoku: Color replaces numbers with 9 vibrant hues, making every puzzle a visual delight that's easy to pick up and impossible to put down.

HOW IT WORKS Fill every row, column, and 3×3 box with all 9 colors — no repeats. The same satisfying logic as classic Sudoku, but the color format welcomes newcomers while keeping all the depth veterans love.

FOUR WAYS TO PLAY → New Game — choose Breezy, Easy, Medium, Hard, or Expert difficulty → Daily Challenge — a new puzzle every day with a unique twist: No Mistakes mode, Time Attack, or Hintless runs. Build your streak. → Expert Mode — wrong placements are allowed. Spot and fix your own mistakes. Every undo counts. → Multiplayer — race a real opponent in real time. Share a room code or get matched instantly.
