Square 36 is a simple math game that can be played solo or with any number of players. The object of the game is to fill the boxes in the Square with numbers that, when added together in a horizontal, vertical, or diagonal row, will add up to 36. It is similar to Circle 36 yet slightly different in how you figure your moves. There are 32 rounds in Square 36 and only 25 in Circle 36.
While it is enjoyable to play Square 36 with friends or family, it is a really good game for playing solo. It is exercise for the brain, and can help a young person develop their minds as they study simple arithmetic in school. It is also a very helpful stimulus to help aging brains stay sharp and focused!
