The Tower of Bozbar, an ancient game of unknown origin, consists of three pegs and a pile of cylindrical weights (usually six of them ranging from 1-ugh to a 6-ugh weight). The goal is to move the pile from one peg to another, moving one weight at a time, with the constraint that no weight can ever be placed atop a smaller weight lest those beneath it be crushed. Many people say that the Tower of Bozbar is a superb method of mental relaxation.

It may be of slight interest that the Jester's Quarters in the ring wing of Flatheadia contained a Tower of Bozbar which opened up various secret passageways depending on which peg all of the weights were upon.

The relationship between this game and the province of Bozbar is unknown.
