RESTORE BY POINTS

An interesting and unusual game in which you are asked to solve a small problem — to restore the drawing by points. Here is a square, the size of which you can choose before starting: 5, 10 or 15 points vertically and horizontally. At the top and left sides of the square, one, two, or three digits indicate each row and column of the square. If a row is signed as 3 1, it means that there should be only four dots in this row, three together and one at least one cell away from these three. The same goes for columns. By putting the required number of dots in rows and columns, and checking that their number strictly coincides with the written one, you will get a hidden picture. This means that you have a digital image map that you can use to restore the image itself.
