Before the game starts, you select a car number from 1 to 7 by turning a knob on the front of the cabinet. Then you insert a coin in the machine. Multiple coins can be inserted to play additional numbers up to and including all 7.
You now receive 5 balls and you play them all at once. The balls roll over the playfield and the ball that enters a numbered slot in the back of the playfield first marks the winning number. The other balls are out. Your score is displayed on the backglass.
It's also possible your ball ends up in a "Blow Out", those are the two end slots in the range. If this happens, you have a flat tyre and don't win anything at all. Now that's what I call logic.
