Donkey was written1 as a way to showcase the capabilities of the BASIC programming language which shipped with new IBM PCs. Therefore one might expect it to be a very simple game–and simple it is:
The object is to avoid the donkeys in the road as you drive. The controls consist of only a single button, the space bar, which is used to switch lanes. Each time you successfully pass a donkey, your car moves a bit closer to the top of the screen, so that it will be more difficult to switch in time to miss the next one. If you hit a donkey, the donkeys are given a point, you explode, and you start over:
Every eleventh donkey that you pass, you are reset to the center of the screen and given a point. The game keeps track of the score, but there’s no particular reward for reaching any certain score; the game just continues until you exit. As simple and unrewarding as this game is, that’s likely to be fairly soon after starting.
Update: I’ve added a video demonstrating the gameplay below.
