This is a 1971 Gottlieb Rollercoaster Pinball Machine. It is the first machine to have wireform ramps later known as habitrails. The machine's gameplay is highly influenced by the spinner in the center of the field. Points are scored when the spinner changes position and when the balls travel on the ramps and down the outlanes. Getting a replay score of 4300 can be easy if the arrow is on 500 or very difficult if it is on 50. There is a twist when playing two players as each player needs to start where the spinner ended for the other player. Advancing the spinner to 500 will be good for you, but can also benefit your competitor. Scoring all of the numbered lights turns 50 point scores into 500 points. This is a fun classic game that is pretty rare today.
