In Divisions A, B, and C, qualifying scores will be drawn from a player’s best attempts on six of the twelve available machines. Each individual attempt on a machine will be weighted against all other attempts on that same machine and ranked on a scale of 0-100 points. This ranking system allows individual game scores from different eras of pinball to be compared directly with one another. Players are permitted as many attempts as they wish on each of the twelve machines within a division, but only their best attempt on six different machines will count toward their overall qualifying score.

In the three classics divisions, competitors will be scored on their best four out of sixteen machines. In all other divisions, competitors will be scored on their best four of the eight machines available. Qualifying attempts for Divisions A, B, C and D may be made any time the facility is open between Thursday morning and closing time on Saturday.
