Sudoku that opens straight into a puzzle. No menu. No lobby. No daily-reward popup. Tap the icon and you're already playing a board pitched at your level. Finish it — or get bored — swipe up, and the next one rises from the bottom. The feed never dead-ends and never tells you to come back tomorrow. ONE PUZZLE AT A TIME, FOREVER - Launches directly into a playable puzzle - Swipe up on the board to move on; the board tracks your finger and springs back if you change your mind - Swipe away a puzzle you never touched and it leaves no trace - Started one? Save it for later, reset it, or skip it - 10,000 puzzles in the catalog, topped up quietly in the background PUZZLES THAT FIND YOUR LEVEL Every board is graded by the reasoning it actually takes to crack — the chain of techniques you have to reach for, not how many squares happen to be blank. Ratings then move with real play as people solve, fail and skip. The app reads your recent solves and picks from the band around you, so the difficulty follows you up. - Easy — a clean warm-up - Medium — needs a plan - Hard — needs a technique - Expert — needs all of them EVERYTHING YOU NEED, NOTHING YOU DON'T There is no hint button. This app won't solve a square for you and won't nudge you toward the next move — the puzzle is yours. It just takes the bookkeeping off your hands. - Self-cleaning notes — place a number and it clears that square's pencil marks and strips the digit from every peer in the row, column and box - Quick Enter — hold a digit, then tap squares to drop it in - Matching digits — the digit you're holding glows everywhere it already sits - Counts on every key — each number key shows how many of that digit are left - Undo and erase — step back through entries, erases and note changes - Mistakes, optional — leave conflict highlighting on for three counted mistakes, or turn it off and find out at the end - Pause — the board hides behind a cover that ignores every touch - Start over — givens back, everything else cleared - A shelf for later — park a puzzle with your entries, notes and elapsed time intact EVERY PRESS TICKS - Controls ease under your finger the instant you touch them - Complete a 3x3 block and the whole block pulses as one piece, with a stronger haptic beat - Finish a row or column and the line pulses the same way — one beat for the line, not nine - Haptics off in one tap - Light, dark, or follow the system — live, with no restart 300 PUZZLES OFFLINE Three hundred boards ship inside the download, so it plays fine on a plane, on a subway, or anywhere with no signal. NO ACCOUNT. NO ADS. NO TRACKING. - No sign-up, no email box, no password — your device is identified anonymously - No ad SDKs, no advertising identifier, and the app never shows the "Allow App to Track" prompt - Nothing sold, nothing brokered, nothing linked to you elsewhere - Crash, performance and basic usage analytics only, listed plainly in the privacy policy ## Version history (last 5 releases) ### 0.5.0 — 2026-08-31 ## What's Changed * [SYN-393] Update app version to 0.5.0 by @CodyEngel in https://github.com/SynessStudios/sudoku/pull/350 * Archive syn-391 and syn-393;
