One board a day, the same for everyone. One rule, one solution. Now in English, Ukrainian, German, French, Spanish, Italian, Polish and Portuguese. Cantle is a daily logic puzzle with exactly one rule: two connected dots can never share a color. That single constraint is enough to build a genuinely hard puzzle. Every board has exactly one valid solution — not "a solution we liked", but a mathematically unique answer, verified before the puzzle ever reaches you. There is no guessing, no hidden information, and no luck. If you can see it, you can solve it. A NEW BOARD EVERY DAY Everyone plays the same puzzle on the same day. Solve it, then see how your time compares against every other player who took on the same graph. Miss a day and your streak is at risk — earn streak freezes by playing consistently, and one will cover a day you couldn't get to. TWO DIFFICULTIES The daily Standard board is a satisfying few minutes. Hard Mode is a second, tougher board each day with its own streak and its own leaderboard, for when Standard stops being a challenge. LEADERBOARDS, GLOBAL AND FRIENDS Compare against everyone, or just against people you have added by friend code. No account, no email, no password — Cantle generates an anonymous profile on first launch and that is all it needs. PRACTICE, WITHOUT LIMITS Unlimited generated boards across difficulty tiers, up to Axiom and Proof — the two deepest reasoning levels, where the chain of deduction runs longest. Practice never touches your streak, so experiment freely. THE FULL ARCHIVE Every board since day one, replayable at any time. BUILT TO BE LOOKED AT Choose board themes, symbol styles, and backgrounds. Symbols can be shown alongside colors, so the puzzle stays fully playable if you don't distinguish colors reliably — the rule is about connection, not hue. PLAYS OFFLINE The daily board loads and solves without a connection. Your result syncs when you're back online. NO ADVERTISEMENTS Cantle shows no third-party ads and uses no advertising trackers. It never has. ABOUT THE NAME A cantle is the raised back of a saddle — the part that holds you in place. It seemed right for a game built on a single rule that holds everything else together. Cantle is free to play every day. Cantle Pro adds Hard Mode, the full archive, missed days, and the deepest practice tiers.

  • This app hasn’t received enough ratings or reviews to display an overview.

Leaderboard ties now show milliseconds, so you can see who was faster and why. Duels notice when your opponent finishes — no more waiting on a result that's already in. Yesterday's place is shown the moment you open the app. Clearer rules: the line under the color tray now always tells you what matters — which shapes are yours, the one rule, or what to do when a line turns red. "How to play" in Settings shows the teaching board on one screen. No more "nodes" anywhere — circles, squares and neighbours. Your profile shows your #tag, so friends can find the right you. Restore works the moment you delete and re-create an account. The app registers reliably on a bad connection, a board opened at midnight stays yours, and the language follows your phone until you pick one. Your place on the day's board is now recorded reliably, and any day that showed "never reached the server" is filled in on the next launch. Plus fixes to French counts, offline Restore, and smaller things.
