Diversion

This fairly ancient Racing Game (my copy seems at least 50 years old) has no dice whatever, an unusual feature for the genre. The gameboard has a series of turntables on it, which can be rotated so as to alter the paths in front of the players: the skillful manipulation of the turntables lies at the heart of the game. Each turn the player's piece (a small racing car) moves 1,2,3, or 4 squares forwards, at the player's discretion. If he lands on a space with black dots, he can rotate a turntable anywhere on the board, either to clear his path to the finish line or to hinder someone else. The Finish squares when reached give you points, and then you return to the start, only winning when you have 100 pts. It is possible to become completely trapped in an area with no black dots, and this carries a penalty of 20 pts and return to start.
The theme is pasted on, but the deduction and 'screwage factor' involved should appeal to many.
