How to play Nonogram
A Nonogram is a picture logic puzzle. Number clues tell you which groups of squares to fill in each row and column.
Read each clue as a group
A clue of 2 1 means two filled squares, then at least one blank square, then one filled square.
Mark what cannot be filled
Use crosses to rule out squares. They do not count as filled cells, but they make the remaining spaces easier to reason about.
Use rows and columns together
Every confident mark gives you information in the other direction. Avoid guessing: every puzzle here has one verified solution.
