SquarO

SquarO is a fun little logic puzzle, reminiscent of minesweeper. In this one though, instead of finding which adjacent squares have mines in them, you have to figure out which of the corners of each square should be filled in. As you solve for each square, the number it contains will turn black, but be careful -- that doesn't necessarily mean that your solution is correct! With four different difficulties, there's a SquarO puzzle for any skill level.
