Top-It! Grand Prix Game

This is a card game using a mixture of 9 types of cards (Start Racing, Slow Trafic, Engine Blows Up, Pit Stop, New Tyres, Tyre burst and 5, 10 and 15 laps). The winner is the first person complete 100 laps by getting five 5 laps cards and three each of 10 and 15 laps cards onto the table in front of them ("the Tableaux")by legal means.
Each player is dealt a hand of 5 cards and a turn consists of drawing one card and either adding a card to his own or opponent's tableaux or discarding.
Lap cards can only be added if certain precursor cards have been laid previously and some of these can be canceled by other cards played onto them by opponents.
