irumea Sudoku

Sudoku that makes you better — not just busy. Other apps make puzzles longer. irumea shows you the technique you need right now and lets you take the step yourself. Every hint names the situation, marks where to look and explains why this is the only way. You keep solving — and learn as you go. SIX CHAPTERS, ONE LADDER Each chapter is a way of thinking, not a difficulty level: • Only One Way — singles • Already Taken — pointing and claiming • One Digit at a Time — X-Wing, Skyscraper and relatives • Tertium non datur — XY-Wing, W-Wing • Two Colors — coloring and chains • What If — forcing chains 160 hand-picked levels, five per technique, built so the technique actually shows up. No puzzle is padded. HINTS THAT EXPLAIN A hint shows you the situation and names the technique. Go deeper if you want — all the way to the reasoning. The digit itself is yours to place. A hint costs one from your balance; you get one back every day. ACADEMY 33 short lessons, one per technique, each with an exercise. Meet a technique in play and its lesson unlocks. Reading is always free. CHECKS At the end of a chapter you show what you've got: puzzles without hints, without coach, without mistakes. DAILY One daily per chapter, stars, streaks with freezes, a calendar. Missed is missed — no pressure, just a rhythm. YOUR RULES Guided or free: see mistakes at once or only at the end. Optional three-mistake limit. Notes, exclusion notes, auto-cleanup, undo — all there, none imposed. BEAUTIFUL Four scenes: Wheatfield, Daisies, Starry Night, Fireflies. Light and dark. Color-blind safe: every meaning is coded twice. PREMIUM & AD-FREE One-time purchases, no subscription. Premium: unlimited hints, no ads, two streak freezes a month, one continue at the mistake limit per puzzle — and every future variant and practice set included. Ad-free is available on its own. HONEST No account, no subscription, no banners, no tracking. An ad at most after a solved puzzle; videos only as an offer with a visible video symbol — never a condition for progress. Your progress stays on your device and in your phone's backup. English and German. By Irumea OÜ.
