Pixel Logic

Use the number clues to fill the grid and reveal a hidden picture. A fresh daily puzzle plus 5×5, 8×8 and 10×10.

How to play

  1. Each number beside a row or above a column says how long a run of filled squares is. Several numbers mean several runs, in order, with at least one gap between them.
  2. Tap a square to fill it. Switch to Mark empty (or right-click) to note squares you know are blank.
  3. A clue turns grey when its row or column matches. Solve when every row and column matches.
  4. Your time is saved as a personal best for each size. The daily puzzle is 8×8 and resets at 00:00 UTC.

Tips and strategy

  • Start with the biggest clues. A 10 in a ten-square line fills it completely.
  • If a clue is larger than half the line, some squares in the middle must be filled even before you know where the run starts.
  • Mark squares you are sure are empty; it stops mistakes and shows what is left.
  • A clue of 0 means the whole row or column is empty.

FAQ

Is there only one correct picture?
Not always. Some clue sets fit more than one picture, so the game accepts any grid that satisfies every clue.
Can I play without a mouse?
Yes. Every square is a button, so Tab and Enter work, and each square announces its row, column and state to screen readers.
