Sudoku League is a logic puzzle game for brain training: no pop-up ads between games, hints that explain why, and real-time battles with players worldwide. ■ A Sudoku Game That Helps You Get Better We wanted more than just another Sudoku game. Solve puzzles, compete with real players, review your solves, and learn the techniques that make you better. ■ Hints That Actually Teach You Most Sudoku hints just place a number: "Put 5 here." Sudoku League tells you "You can use a Naked Single in this cell," then shows you why with lines and colors on the board. From Singles to X-Wing, Swordfish, AIC Chains and ALS, we support 40+ solving techniques. Our hints teach you how to find the answer yourself. ■ Real-Time 1v1 Ranked Matches Challenge real players from around the world. You both solve the same puzzle while watching each other's progress. Three mistakes and you lose, so accuracy matters as much as speed. No AI bots. Only real players. ■ Climb the Leaderboard Wins and losses move your rating through Bronze, Silver, Gold, Diamond, Master and Challenger. Seasons last a month, and your record is saved when each one ends. ■ Claim: A New Way to Battle Share one board with your opponent. Place the right number first to claim the cell and its points. Empty cells grow bigger bounties, and a wrong number locks you out for a few seconds. When the board is full, the highest score wins. ■ Play with Up to 8 Friends Challenge 2–8 friends to a race on the same puzzle, or split one board in Claim. Settle a bet or find out who's the best. ■ Daily Sudoku · Compare Your Records Worldwide Solve the same puzzle as players around the world every day and compare your time. Solo games count too: the result screen shows which top percent your time lands in for that difficulty. ■ Collect Rewards, Pick Your Style Every solve earns XP, and leveling up unlocks titles and completion effects: digit rain, halos, stamps, balloons, shooting stars and fireworks. Limited-time events bring effects and nickname colors you can only earn while they run. ■ Play Your Way Blind: no warnings for wrong numbers. Fill the board, then submit. Paper: highlights and note help are off too, just like solving on paper. ■ 6 Difficulty Levels · Offline Play From beginner-friendly to challenging, enjoy unlimited number puzzles across 6 difficulty levels, even with no internet connection. ■ Premium The core experience is free. Premium removes ads and adds features to help you improve. 1. No Ads · Unlimited Hints, Auto Notes & Revive Ads in the free version only appear when you use these three. Premium removes them and lifts the limits. 2. Replay Review your solve one move at a time, see why each number went where it did, and jump back to where you got stuck. 3. Technique Practice Learn X-Wing, XY-Chain, Swordfish and more through examples, finding methods and hands-on boards. (Full House, Naked Single, Hidden Single, Pointing and Claiming are free.) 4. Premium Themes 6 retro pixel theme packs, each in Light and Dark. 5. Puzzle Favorites Save puzzles you want to play again. ■ Premium Plans • Monthly Premium: Auto-renews every month • Annual Premium: Auto-renews every year • Lifetime Premium: One-time purchase, no renewal Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period, and are charged at renewal.
