Sudoku the way it should be — calm, focused, offline. Seven modes to suit any mood: from quick 6×6 puzzles for a coffee break to a lifelong Journey of levels that keep getting harder. MODES • Classic — familiar 9×9 sudoku with clean rules. • Journey — levels that get progressively harder every 10 steps. Your progress saves automatically. • Twist Journey — the same idea, but every level uses irregular jigsaw regions. • Twist — a single freestyle board with jigsaw regions. • Infinity — an endless board: finish one, the next appears seamlessly. • Zen — no timer, no mistake counter. Pure logic without pressure. • Mini 6×6 — a quick 2–3 minute game when you only have a moment. DAILY CHALLENGE A single board every day for every player. Solve it to keep your streak alive. A calendar tracks every day you've completed, and unlocks a set of "streak" achievements as you go. QUALITY-OF-LIFE • Smart hint — first tap highlights a logical cell so you can figure it out yourself; a second tap reveals the answer. • Pencil notes, undo, real-time conflict highlighting. • Auto-resume — swipe away, close the app, come back tomorrow — the game picks up exactly where you left off. • Pause any game manually or automatically when the app goes to background. • Confetti when you win. Haptic feedback (toggle it off if you don't like it). • Choose an accent colour that fits your style.
