About this app
A sudoku for unhurried hours. Paper-textured boards. Editorial type. A daily puzzle that quietly waits for you. Pick a level, pick a theme, settle in. Sudoku at this pace isn't a race — it's a routine. The grid is a place to slow down for ten minutes. The pencil notes are real pencil notes. Mistakes are reset-able. The timer is there if you want it. WHAT'S INSIDE — Ten difficulty levels, from a soft warm-up to a true brain-twister — Daily challenge with a streak that doesn't punish a missed day — Five typography-driven themes: Paper, Sepia, Ink (dark), Midnight, Daylight — Twenty short technique tutorials, from naked single to forcing chain — Smart hints that explain the move, not just point at it — Three mistakes per game, revive with energy or a rewarded ad NO NOISE — No subscriptions, no paywalls — every level, theme, and tutorial is free. — No accounts. No sign-in. No social feed. — No banner ads, no interstitials. The only ad is one you choose to watch for an in-game reward. — No push notifications. The daily puzzle is there when you open it. — Nothing sold, no advertising profile of you. See our privacy policy for what the game collects. OFFLINE FIRST Every puzzle is fully playable in airplane mode. The game saves your progress between sessions. Energy you earn from solving puzzles stays in your pocket forever — no daily resets, no expiring boosts. DESIGNED LIKE A NOTEBOOK The board uses a calm cream paper texture, a deep ink-on-paper typeface, and a single rust accent for the values you place yourself. Switch to Sepia for a warmer reading-light look, Ink for soft dark mode, Midnight for deep navy with gold accents, or Daylight for a bright by-the-window palette.
