Sudoku Just Evolved

Free · Designed for iPad. Not verified for macOS.

Sudoku was the warm-up. Tsuidoku is the real game. Tsuidoku is a logic puzzle for players who have mastered classic Sudoku. The 9×9 grid remains, but a fourth constraint changes everything. THE 4 RULES Each row, column, and 3×3 region must contain the numbers 1 through 9 AND the 9 colors. The twist: each color must also contain all 9 numbers. The result: 81 unique number-color pairs. Place a "Red 5," and it cannot appear anywhere else. DAILY CHALLENGE A unique global grid every day—the same one for the whole world. Maintain your streak, earn monthly medals, and check the daily rankings. MASTER THE TECHNIQUES - Rainbow Technique: Track a single number across all nine colors. - Color Wheel: Track a single color across all nine numbers. Tap a cell to cycle through highlight modes and see the logic light up. PLAY TOGETHER Add friends, compare stats, and chat directly within the app. A detailed profile tracks your records across every difficulty level. Think you’ve mastered Sudoku? The real game starts here. Download now and create your first 81 perfect pairs.
