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.
