About this game

If you've solved hundreds of sudokus and nothing challenges you anymore β€” this is what's next. Not a variant. A new logic puzzle.

🎯 One extra rule changes everything

Classic sudoku: fill every row, column, and 3Γ—3 box with 1–9. Tsuidoku adds a 4th rule β€” every color must also run 1 through 9.

The result: 81 unique number-color pairs, no two cells alike. Sudoku repeats each digit 9 times; Tsuidoku never repeats anything. Every grid you finish is one of a kind.

🧠 A new way to think

Numbers help you place colors. Colors help you place numbers. You read the grid two ways at once β€” reasoning that's simply impossible in sudoku. Every classic technique still works, plus two you'll only learn here.

πŸ† Two modes

Practice β€” no timer, no pressure, your pace.
Ranked β€” every game feeds your rating and your rank on the global leaderboard.

🌍 Compete worldwide

Winning streaks, best times, personal records, peak rating β€” track it all against players everywhere.

Add the 4th rule. See what sudoku becomes.
Sudoku was the warm-up. Tsuidoku is the real game.

What’s new

KODOKU. A mode opens up for players who reach the Tsuidoku league. Five levels, and on each one the clues draw a shape: star, heart, cross, eye, spiral.

The grid, and nothing else.

Settings of its own, a silhouette for every level, and the grid identifier. Interface polish.
