Killer Sudoku for people who hate ad-bloated puzzle apps. Bento is a hand-curated Killer Sudoku game for iPhone and iPad. No ads. No subscription. No login. No tracking. Just puzzles, made for the bedside table. WHAT'S KILLER SUDOKU? It's the Sudoku you know - fill the 9×9 grid so every row, column, and 3×3 box has the digits 1–9 - with a twist: the grid is divided into colored "cages", and the digits inside each cage must add up to the cage's number (with no repeats). It plays like Sudoku crossed with a math puzzle, and once you've tried it, regular Sudoku starts to feel one-dimensional. REGULAR SUDOKU The classic game, no cages. Rows, columns and boxes, nothing else to keep in your head - the one you already know how to play, built with the same care as the rest of Bento. 100 HAND-CURATED PUZZLES Every puzzle in Bento is generated and verified for a unique solution - no broken puzzles, no guesswork required. 20 Easy / 25 Medium / 25 Hard / 30 Expert across the adult catalogue. Plus a fresh daily puzzle every day, free forever. KIDS MODE A separate catalogue of 48 puzzles on smaller 4×4 and 6×6 grids - perfect for teaching the cage-summing mechanic to a young learner. Brighter colors, more forgiving scoring, more hints. Toggle on the home screen. ONE-TIME UNLOCK Bento Pro is a single in-app purchase - no recurring charges. You get every puzzle in adult and kids modes, every difficulty. Try the first 3 puzzles of every difficulty plus the daily puzzle for free, indefinitely. No coercive trial periods, no manipulative free-but-not-really tier. DESIGNED FOR FOCUS • Neobrutalist sticker UI - bold colors, satisfying tactile feel • Classical-grid mode for purists who want plain white cells • Strict mode (3-mistake game over) for players who want the tension • Per-puzzle stars track your cleanest solves separately from your fastest • Full undo history, smart hints, pencil notes • Replay any solved puzzle; share your trophy card as a PNG • Daily streak counter PRIVACY-FIRST Bento collects nothing. No account, no analytics SDK, no ad network, no server you talk to. Everything lives on your device. The only network call the app makes is to Apple's StoreKit when you tap "Unlock for Bento Pro" or "Restore Purchase." WHO IT'S FOR • Sudoku players bored of vanilla 9×9 and looking for the next twist • Parents who want to teach their 6-year-old logic puzzles without screens of ads • Anyone who's deleted a "free" Sudoku app after the third 30-second ad in five minutes Privacy Policy: https://sararu.net/bento/privacy-policy.html Terms of Use: https://sararu.net/bento/terms-of-use.html
