is a logical binary puzzle game played on a square grid.
according to the following simple rules:
- there can be at most two 0s or 1s next to one another. (ex. 00 is OK, but 111 is not. 010 or 101 are just fine!)
- each row and column should contain an equal number of zeros and ones. (ex. if the grid is 6x6, then a row or column must contain no more than three 0s and three 1s)
- any two rows can’t be completely the same, similarly, two columns can’t be the same
