Blotbook: Nonogram Puzzles

Paint the grid with pure logic and reveal a hidden picture. 509 hand-drawn pictures, colored puzzles, a daily challenge, weekly quests and Blot, your clumsy ink-blob pal.

Blotbook is a cozy nonogram notebook. Use the numbers on each row and column to decide which squares to paint and which to mark with an X. Solve the grid and a pixel picture appears on the page.

Every puzzle has exactly one solution and can be solved with logic alone. No guessing, ever.
