Fill-a-Pix is a logic puzzle where each numbered cell tells you how many of its 8 neighbors are filled. By using logical deduction, you determine which cells to fill and which to leave empty, ultimately revealing a hidden pixel art picture.

How do you solve a Fill-a-Pix puzzle?

Start with cells showing 0 (all neighbors empty) or maximum numbers (all neighbors filled). Then use cross-referencing between overlapping cells to narrow down remaining cells. Every puzzle can be solved through pure logic without guessing.

Is Fill-a-Pix the same as Nonogram?

No. Nonogram uses row and column number clues (runs of filled cells). Fill-a-Pix uses per-cell neighbor count clues (0-9). They require different solving strategies but both reveal hidden pictures.
