Your first nonogram.

Use the number clues to work out which squares to fill and which to leave empty. This little 5×5 puzzle walks through every deduction, with no timer or penalties.

A clue of 3 means three filled squares together. Empty squares may appear before or after that group. Multiple numbers describe separate groups in order, with at least one empty square between them.

What makes a move certain?

A square is certain when every legal placement of its clue agrees about it. For a group of three in five squares, try sliding the group all the way left and then right: both placements cover the center. That center square must be filled.

Fills and marks work together

A mark means a square is definitely empty. Once a group reaches its required length, marks keep it from growing by accident. A row deduction also tells you something about each crossing column.

On the daily game, use Fill and Mark, drag along a line, or enable precision controls on a phone. You can revise a square; an incorrect completed line costs ten seconds. Pausing hides the clues and stops your timer, but makes the run unranked.
