SMALL SQUARES. BIGGER PICTURES.
A few numbers. A picture to discover.

The rules in a minute
- A number gives the length of a continuous group of filled squares. Clues 3 1 mean a group of three, then a group of one, with at least one empty square between them.
- Read row clues left to right and column clues top to bottom. Use the rows and columns together; the group lengths and order must match in every line.
- Use Fill for a proved filled square and Mark for a proved empty square (X). Leave an undecided square blank. A clue of 0 means the whole line is empty.
Questions before you play
Where should I start?
Try a 10 × 10 Free Play puzzle for a short, complete picture. If you are new to the clues, the How to play guide explains the rules and includes worked examples.
Do I need to guess or recognise the picture?
No. The current puzzles have been checked to solve from an empty board using row-and-column logic. Fill only squares that follow from the clues, rather than from what the picture might be.
What can I do when I get stuck?
Look for zero lines, completed groups that need X marks, and rows or columns changed by your last move. Use Undo to revisit a mistake. Each puzzle has one free guided step; your hint balance refills to 3 each UTC day.
