Picross

The goal consists in finding the black boxes in each grid.

The figures given on the side and in top of the grid give you indices. They indicate the size of the blocks of black boxes of the line or the column on which they are.

For example 3,4 on the left of a line indicates that there is, from left to right, a block of 3 black boxes then a block of 4 black boxes on this line.
