The purpose of the game is to help the player learn to add and subtract fractions. In this simple two-dimentional game the player will choose a path for a car to drive so that it stops at every "Destination" point, and does not run out of gas. Refueling is possible by driving to a "Gas Station" point. Sections of the road have the amount of gas required displayed next to them (as a fraction of the gas tank capacity). More details can be found in the rest of this document.
