The Game of Sixty-Six

This undated game from Rosebud Art Co. is a spin-and-move game with a mathematical twist that is not nearly as easy as it looks. The board consists of five concentric circles of numbers connected by paths. There are four color-coded spaces in the corners and four matching spaces numbered 66 at the center.

The number spaces range from minus 9 to plus 8. The spinner is unusual - it has 12 outcomes that include 2 x 0, 3 x 1, 2 x 2, 2 x 3, and one each of 4, 5 and 6. The rules say that after making a spin, each player must move his token that number of spaces, forwards, back or sideways.

The player must add or subtract the number in each space he passes or reaches and keep a cumulative total from one turn to the next. The winner is the first to successfully reach the 66 space of their color with a cumulative total of exactly 66.

A copy of the game from renowned collector Alex G. Malloy's estate includes a hand-written attribution of the cover art to Palmer Cox, the Canadian artist famous for his books and comics about Brownies. As Cox died in 1924, this implies an early-to-mid 1920s publication date.
