One popular origin for back to square one has to do with the game of hopscotch. This popular children’s game required the creation of a series of squares, with each square containing a number. As part of the game, a participant must traverse the grid of squares, eventually making the way back to the home square of one, where it is possible to start all over again.

With this board game, landing on a square that is connected with a slide may either cause the player to go back a level, or in the case of a few squares return the player all the way to the first square on the board. Critics of this explanation note that the phrase had been popular for a number of years before this particular board game was developed, although there is some merit in seeing the game as being one means of increasing the popularity of the idiom.
