About this app

One stroke. Every square. Don't run dry. Kasure is a daily logic puzzle drawn in ink. Put a finger on the ink dot and draw one continuous stroke through every square on the paper, ending on the red seal. The catch is the whole game: every square costs a drop of ink. When the brush runs dry the stroke stops. Ink pools refill it. So the question is never just which path covers everything — it's which path covers everything and still reaches the next pool in time. The brush thins and frays as it dries, so the stroke you leave is a record of how you thought. Every puzzle has exactly one solution. No luck, no timers, no lives. A NEW PUZZLE EVERY MORNING Monday is a warm-up. The week tightens. Sunday is the long stroke. Sign it, keep your streak, and share the result as a small ink-wash of how it went — without giving the route away. Every seven days in a row earns a rest day, so one missed morning doesn't cost you the streak. Free, every day. THE GOLD SEAL Sign a board in a single forward stroke — no clear, no undo, no hint — and the seal is gold. It's the game inside the game. SIX WAYS TO PRACTICE Warm-up, Regular, Deep and Sunday, plus two variations: Order, where numbered squares must be inked in sequence, and Dry paper, where rough squares drink two drops. 500 puzzles for the days when one isn't enough. The first ten of each classic tier and the first three of each variation are free. LEARN BY DRAWING Three short lessons teach the whole game with your finger, not a wall of text. Stuck later? One free hint per puzzle shows where to go next. QUIET BY DESIGN Warm paper by day, dark paper by night. No ads, no account, nothing counting down at you. A home and lock screen widget shows today's seal and your streak. Your results follow you to a new phone through iCloud. Friends' board on Game Center — opt-in, never during a stroke. FOR EVERYONE VoiceOver can play every puzzle, one square at a time, and hears where the brush is and how much ink is left. Larger text and Reduce Motion are respected.
