My wife and I have a set of dominoes that go up to double 12s. (For those not familiar with this game, it consists of a number of tiles, where each tile's face is divided into two parts. Each part can have one to twelve spots (or pips I think they are called) or can be blank.
While playing yesterday, I got to thinking how many tiles would make a complete set. The box that the tiles are stored in says there are 91 tiles in this set.
Can anyone come up with the reason for this number?
