Nonograms: free picture puzzles

What is a nonogram?

A nonogram is a logic puzzle that hides a picture. The numbers beside each row and above each column tell you how many squares to fill in, and in what groups. Work out which squares must be filled and which must stay empty, and a small drawing appears.

A clue of 3 1 means a run of three filled squares, then at least one gap, then a single filled square. The clues never tell you exactly where the runs start. Working that out is the puzzle. There's a walkthrough in how to play nonograms.

Choose a size

• 5×5 nonograms take about a minute and are perfect for learning.
• 10×10 nonograms are the classic size and the size of the daily puzzle.
• 15×15 nonograms are for a longer sit with more detailed pictures.

Every picture solves by logic

Each drawing here has been run through a line solver. It has exactly one solution, and you can reach it by reasoning one row or column at a time, so you never have to guess. The pictures are original drawings made for GridPorch.

Controls

Drag across squares to fill several at once. Switch to Mark ×, or right-click, to rule a square out. On a keyboard, arrow keys move, Space fills, and X marks. A row or column's clue fades when it's complete. Filling a square that should stay empty counts as a mistake and leaves a ×. You also get three hints per puzzle. Prefer paper?
