🖼️ Picture Grid Logic
Fill squares to match the number clues on each row and column and reveal a hidden pattern. Every puzzle can be solved by logic alone.
How to play
Each clue lists the blocks of filled squares in that row or column, in order. “3 1” means three filled squares in a row, at least one gap, then one more. Start with rows that have big numbers, mark squares you know are empty, and clues turn green when they match.
⌨️ Keyboard: arrow keys move, Space fills a square, X marks it empty.
What it teaches
These puzzles (sometimes called nonograms) need careful deduction: you only fill a square when you can prove it must be filled. That is the same reasoning used in maths proofs and debugging code. Every puzzle here is checked so it can be solved without guessing.
Levels: 5 × 5 (Small grid) · 8 × 8 (Medium grid) · 10 × 10 (Big grid)
