Racetrack

## Description

_Racetrack_ is based on a pencil and paper game published in Martin Gardner’s
Mathematical Games column in Scientific American (May, 1973). Up to five
contestants can input their acceleration (direction and magnitude) each turn
while racing on an elliptical track. The HP programmable calculator checks for
collision with the track’s bounds and updates the racers to the new position.
It’s up to the players to keep track of where everybody is.
