The honest nonogram: every puzzle has exactly one solution, reachable by pure logic. No guessing, no timers, no energy. Saku is the calm, honest nonogram — a picture-logic puzzle (also called Picture Cross or Griddlers) with none of the noise. No lives, no energy, no timers. Every puzzle is uniquely solvable by pure logic — never by guessing — so a solve always feels earned, and the hidden picture blooms when you finish. • Five sizes, from a quick 5×5 to a deep 20×20 • A Daily puzzle — the same one for everyone, worldwide • True-black OLED night mode, gentle on tired eyes • Tactile fill-and-cross with soft haptics • A kind hint that only ever reveals a logically forced move • Puzzles play offline. No account. Only the ads need a connection. One quiet Studio Unlock — paid once, yours forever — opens extra ink-and-paper palettes, removes the ads, and supports a tiny independent studio. The puzzles stay free. Made with care by Erek Studio.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Fixed the Daily puzzle rotation so it now advances every day. Free play is now ad-supported: a short ad before a puzzle opens, and you can watch one for a single hint. The Studio Unlock removes the ads and keeps every palette. Puzzles are unchanged — still uniquely solvable, still no guessing.
