Online Nonograms / Griddlers

O

The purpose of this game is to discover a board made up of blue squares and free spaces. You can do this by looking at row/column definitions: a sequence of numbers that describe groups of consecutive squares appearing on that row/column. For example, 1 5 2 means one square, 5 squares and 2 squares, in this order, separated by one or more spaces between them. You can click the squares once in order to mark them as occupied. Clicking them again will mark them with an X; you can use this sign to track the squares that you consider to be empty. Clicking them again brings the squares in their original state.
