Sudoku League - Brain Puzzle

Sudoku League is a logic puzzle game for brain training: no pop-up ads between games, hints that explain why, and real-time ranked races.

■ A Sudoku Game That Helps You Get Better

We made Sudoku League because we wanted more than just another Sudoku game.

Solve puzzles, compete with real players, review your solves, and learn the techniques that make you a better Sudoku player.

■ Real-Time 1v1 Ranked Matches

Challenge real players from around the world in real time.

You and your opponent solve the same puzzle simultaneously while watching each other's progress.

Make three mistakes and you lose, so speed isn't everything. Accuracy matters too.

Climb the ranks and prove your Sudoku skills.

No AI bots. You play against real players.

■ Play with Up to 8 Friends

Challenge 2–8 friends to a Sudoku battle.

Settle a bet, compete with your friends, or simply find out who's the best at Sudoku.

■ Daily Sudoku

Solve the same puzzle as players around the world every day.

See how quickly you solved today's puzzle and compare your result with other players.

One puzzle a day. Keep improving.

■ 6 Difficulty Levels of Number Puzzle · Offline Play

From beginner-friendly puzzles to challenging ones, Sudoku League offers 6 difficulty levels.

No internet connection? No problem.

Play offline and enjoy unlimited Sudoku puzzles wherever you are.

■ Hints That Actually Teach You

We were surprised by Sudoku apps that give you a hint by simply placing a number on the board.

"Put 5 here."

That's not the kind of hint we wanted.

Instead, Sudoku League might tell you:

"You can use a Naked Single in this cell."

Then it shows you exactly why using lines, highlights, and colors on the board.

From Singles to X-Wing, Swordfish, AIC Chains, ALS, and more, we support 40+ solving techniques.

Our hints don't just give you the answer.
They teach you how to find it yourself — a logic brain workout every game.

■ Premium

You can enjoy the core Sudoku League experience without Premium.

Premium removes ads and adds features designed to help you improve and enjoy Sudoku even more.

1. No Ads · Unlimited Hints, Auto Notes & Revive

Ads in the free version only appear when using Hints, Auto Notes, or Revive.

Premium removes these ads and lets you use all three features without limits.

2. Replay

Review your entire solve, one move at a time.

Our solving analysis tracks how you solved the puzzle and helps explain why each number was placed where it was.

You can also jump back to where you got stuck and try solving from there again.

Review your mistakes, understand your decisions, and improve your solving skills.

3. Technique Practice

X-Wing, XY-Chain, Swordfish, and more.

Learn advanced Sudoku techniques through examples, explanations, finding methods, and hands-on practice.

Don't just memorize the name of a technique.
Learn how to actually find and use it.

4. Premium Themes

Give your Sudoku board a retro-inspired pixel look with 6 premium theme packs.

With Light and Dark modes, you can enjoy 12 additional theme combinations.
