About this app
A clean, classic sudoku that gets out of your way. Every puzzle is generated fresh and checked to have exactly one solution — no guessing, no dead ends. Six difficulty levels take you from a gentle start to grids with the bare minimum of clues. FEATURES • Six levels: Easy, Medium, Hard, Expert, Master, Extreme • Pencil marks for candidate numbers, exactly as you would on paper • Undo and redo as far back as you like • Hints when a grid stops giving • Mistake counter and a running timer • A chime each time you finish a row, column or box • Scoring that rewards speed and accuracy, with a multiplier per difficulty • Per-level statistics: best score, average score, average time • Six colour themes, each with a light and dark version • Twelve languages • Your game saves itself — close the app mid-puzzle and pick it up later NO INTERRUPTIONS No adverts. No account. No timers pushing you to buy anything. The game works completely offline and collects nothing about you. HOW SCORING WORKS Score = (1000 + time bonus) × difficulty multiplier − mistakes ×50 − hints ×100 The time bonus counts down from 900 seconds, so a faster solve scores higher. Harder levels multiply the result by up to 3.5.
