Fancy a li'l Sudok? Here is the new Sudoku app, with no advertising, no in-app purchases and no trackers, offering unique verified grids and innovative game modes built to be ideal for seasoned players. AT A GLANCE • Verified grids with a single solution and rising complexity • Innovative input modes, adjustable level of assistance • Built for seasoned players and the various solving techniques • Timer and statistics, your game saved at all times • Optional colour themes and dark mode • No advertising, no in-app purchases, no trackers, no player database • Built-in documentation and guide VERIFIED GRIDS WITH A SINGLE SOLUTION AND RISING COMPLEXITY Every grid is checked before it reaches you: one solution only, always reachable by reasoning. You will never have to guess or take a chance. Nine tiers, from Beginner to Demonic, calibrated not on the number of given digits but on what the grid genuinely demands. INNOVATIVE INPUT MODES, ADJUSTABLE LEVEL OF ASSISTANCE Select a cell and adjust its values, or select a value and spread it across the grid in series. A long press combines two gestures into one. And when a final choice makes some candidates obsolete, Sudok switches to that value by itself to help you clear them. Each aid is enabled separately — visual guides, matching values, automatic candidates, dynamic selection: you set the dial where you want it, and move it whenever you please. BUILT FOR SEASONED PLAYERS AND THE VARIOUS SOLVING TECHNIQUES The higher tiers call for reasoning, not patience: scanning, naked and hidden singles, pairs and triples, locked candidates, X-Wing, Swordfish, Y-Wing. Each technique is introduced at its own level, never before. Demonic grids genuinely require the advanced patterns — and reward them. TIMER AND STATISTICS, YOUR GAME SAVED AT ALL TIMES Timer, best time and average for each of the nine levels. Revealing a mistake or the solution stops the clock for good and keeps that game out of your statistics: your records stay honest. Your game is saved continuously — leave whenever you like, come back weeks later, everything is in its place. OPTIONAL COLOUR THEMES AND DARK MODE Seven contrast colours, in light and dark: fourteen themes. The interface stays plain, and colour signals one thing only — your actions. NO ADVERTISING, NO IN-APP PURCHASES, NO TRACKERS, NO PLAYER DATABASE You pay once, that's all. No banner, no unlock to buy, no tracker, no account, no network. Sudok works entirely offline and collects no data: nothing leaves your device. BUILT-IN DOCUMENTATION AND GUIDE Rules, input modes, options and solving techniques: everything is explained inside the app, diagrams included. ## Key features - Verified grids with unique solutions - Progressive difficulty levels - Innovative input modes - Configurable assistance levels - Advanced solving techniques - Continuous game saving - Optional color themes and dark mode ## Is Sudok safe?

Aucune pub pour seulement 50 centimes, il est simple et pleins de bonnes fonctionnalités ! ### 5/5 — Super cool *2026-09-20* Enfin une application de Sudoku où tu peux gérer tes notes et ta grille sans changer constamment de mode. Avec les options en plus et les appuis longs je gagne pas mal de temps pour avancer et mieux gérer la confirmation ou le retrait de mes notes, même si au début c’est un coup à prendre. Merci aux devs ! ## Frequently asked questions about Sudok ### Does Sudok have ads? No, Sudok is completely free of advertisements.

The same app, in a window, portrait or landscape. Menus and keyboard shortcuts: a digit places the value, ⌘ and a digit the candidate. Included in your purchase. • HINTS. One cell has you stuck? Ask for that one, and only that one. You reveal what you want, when you want. • ERRORS, ON YOUR TERMS. Sudok shows your mistakes in red; you choose which ones to wipe. The rest stay put. • SOLUTION, ONE CELL AT A TIME. The solved grid appears: take one cell, two, or ten. What you keep is written in colour. • CANDIDATE ASSISTANCE. Lock a digit: every cell that can no longer take it turns grey. Only the cells where the candidate makes sense stay white. The scanning is done for you. • REFINED DISPLAY. Animated arrival on the home screen, reworked highlights, adopted digits in bold and in colour. • AND THE REST. Steadier automatic behaviours, clearer settings, fixes of every kind. Still no ads, no in-app purchases, and fully offline. ### 2026.1 — 2026-08-18 No release notes. ## Apps similar to Sudok | App | Rating | Price | Category | | --- | --- | --- | --- | | [Sudoku Royale: No Ads](https://appshunter.io/ios/app/sudoku-royale-no-ads/id6759472395) | 4.7 (18) | Free | Games | | [Sudoku - No Adverts, Ad Free!](https://appshunter.io/ios/app/sudoku-no-adverts-ad-free/id521559009) | 4.6 (607) | Free | Games | | [Sudoku - No Ads & Offline](https://appshunter.io/ios/app/sudoku-no-ads-and-offline/id6502922368) | 4.8 (774) | Free | Games | | [Sudoku - Classic Math Games](https://appshunter.io/ios/app/sudoku-classic-math-games/id6550913213) | 4.9 (6,576) | Free | Games | | [SmartGo One](https://appshunter.io/ios/app/smartgo-one/id1465746992) | 4.8 (1,984) | Free | Games | | [Sudoku ∙ Classic Sudoku Games](https://appshunter.io/ios/app/sudoku-classic-sudoku-games/id1522685808) | 4.7 (24,291) | Free | Games | ## More apps by David Rochaix - [CR-8000](https://appshunter.io/ios/app/cr-8000/id1441966351) - [CR-5000](https://appshunter.io/ios/app/cr-5000/id1442843535) - [DRM-32](https://appshunter.io/ios/app/drm-32/id1488347182) - [DRM-16](https://appshunter.io/ios/app/drm-16/id1489333688) All apps by David Rochaix: https://appshunter.io/developer/1441966350 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
