is a puzzle based on a grid of black and white squares which form a picture, like this:
Lists of numbers representing the number of black squares are added to each row and column. Each number represents a group of black squares so, for example, "3 2" means that on this row there is a group of 3 black squares to the left of a group of 2 black squares, with one or more white squares in between. (There must be at least one white square between the groups, or the 3 and 2 would join up to become a 5).
The numbers are always in order, so "3 2" means 3 black squares to the left of 2 black squares, and "2 3" means 2 to the left of 3.
Have a look at the following picture to familiarise yourself with this system.
Finally, the picture is hidden, leaving you with the task of reconstructing it from the clues alone!Free for today only
