Square 36

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!

Note the vertical row on the left. The player was able to leave two spaces empty during the course of the game with the row already totaling 36. These spaces provided a place to add zeros when the sum and difference option was used in other vertical rows.
This is the original scoresheet from 1991. The point system has been changed and a few rules rewritten.
