Sudoku League
Race someone. Climb the ranks.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Get better — then prove it.
• Practice mode — pick a technique, drill it
• Step-by-step hints — reasoning, not answers
• Ranked races — live, matched by rating
■ Real-time 1v1 races
Get matched with a player near your rating and solve the same puzzle at the
same time. You can see how far along they are the whole way, so it stays tense
to the last cell. Three mistakes and you lose — accuracy counts as much as speed.
■ Ranked seasons
Wins and losses move your rating across six tiers: Bronze, Silver, Gold,
Diamond, Master, Challenger. Seasons run a month; when one ends your standing
is archived, ratings partially reset, and the next one opens.
■ Play a friend
Create a room code, share it, and race someone you know. Ratings don't move.
■ Daily Sudoku
One puzzle a day, the same for everyone, with a leaderboard for the day.
■ Six difficulties, playable offline
Bronze through Challenger, no connection needed. Every puzzle has exactly one
solution and is verified to be solvable by logic alone — never by guessing.
■ Hints that don't hand you the answer
Instead of "put a 5 here", you get "there's a naked single in this cell", drawn
on the board with the lines and colors that show why. Over 40 techniques, from
singles to X-Wing, Swordfish, AIC chains, and ALS.
■ Technique codex and practice (premium)
Techniques you've used collect in a codex, and you can pick one to drill on a
board built to feature it, walked through step by step.
■ Premium
Unlimited ad-free hints and auto-notes, replays (step back through a game and
resume from any point), puzzle favorites, five theme packs, technique practice.
• Premium Monthly — auto-renewing every month
• Premium Yearly — auto-renewing every year
• Premium Lifetime — one payment, never renews
A subscription renews automatically unless cancelled at least 24 hours before
the period ends, and is charged at renewal. Cancel any time from your App Store
account settings. Prices are those shown on the App Store.
