Released in July 1974. Twin Racer was a 1- or 2-player Kee Games copy of "Gran Trak 20
". This game added the new feature of the Ram Effect, which allowed you to knock your opponent off the track. Free play was awarded at 20 points instead of Gran Trak's 40. Another Kee Games innovation with this game was the Automatic Drive Button, which was advertised as 'for ladies and kids – must for arcades'.
