20 taxis are divided equally among players. In turn, each player rolls the die and either places one of their taxis on the indicated color (or any color if the "?" is rolled) or takes a taxi from each of the other players (if the police officer is rolled). First player to get rid of all their taxis wins.
This game can be played as a stand-alone game or can be used in conjunction with any monopoly game. Special rules for playing with classic Monopoly are included.
