Control either Julius Erving or Larry Bird in front of a single basket, in a game of one on one. The user can select to play either to a certain score or for a certain amount of time. When on offense, the player can rotate to keep away from his rival, take a shot from a distance or move in to the basket for special up-close slam-dunks. When on defense, you can try to take your rival's ball or jump up to block a shot. Particularly good set-ups get a slow-motion replay. You can even smash the glass on the backboard, which will send an irate janitor onto the court to clean up the mess.

This was the first computer game with celebrity endorsements.

Copy protection

This game became successful on the Commodore 64, where its complicated copy-protection became famous not only with hackers intent on breaking it, but with users who had to listen to it tear their old behemouth 1541 floppy drives a new one. The PC copy protection was similarly legendary--96 sector headers on track 15 took a long time to figure out and duplicate.


The concept was created by Hawkins based on his recollections of the 60's era "One on One" televised sports contests, sponsored by hair tonic Vitalis.
