## What is Saku?

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.

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.
