Description from the back of the box. ©1978 Magnavox Consumer Electronics Company Multi-mode game cartridge by Magnavox. Bowling! A true electronic simulation! You go straight for the pins or hook from either side of the alley! But once you commit to the hook--you're on the hook! There's no going back. Digital scoring! Sync-sound action! Two to four players. (Lanes change color to let you know when it's your turn.) Basketball! For ultimate realism, there's even a built-in electronic gravity field! The electronic basketball bounces like a real basketball. If you don't get a clear shot into the basket, the ball hits the rim or the backboard and bounces back into the court! On-screen digital scoring and timer. Sync-sound action! Two players.
