a point value based on how it compares to all of the other entries on that same machine: 100 points for the highest score, down to 1 point for 88th place, and 0 points for all lower scores. This point value may decrease over time as more games are played by everyone. An entry's overall score is the sum of these point values; thus, it too can decrease over time. A player's best entry over the course of the qualifying period determines the player's qualifying score, and the qualifying scores are used to determine the rank of each player. A player's rank may go up or down, even without continuing to play more entries. There is a fair amount of strategy that can be employed to deal with this. At the end of the qualifying period (typically several days), the top-ranked players in each division (the actual number varies) compete in a head-to-head, bracketed format to determine the winners. The tournament also includes a Juniors division (16 years or younger), a Seniors division (50 years or older), and a Classics division that runs on multiple days of the event. In 2014, the Juniors division was changed to be three tournaments run on consecutive days, similar to the Classics division. In 2015 a D division was added, specifically targeting very new players who had only played a limited amount of competitive pinball. In order to qualify for D division, a player needed to have a world ranking of 7500 or lower. In 2018 and 2019, the Women's International Pinball Tournament (WIPT) was added in parallel to the Pinburgh event at Replay FX, utilizing the Pinburgh format. Tournament machine configurations If possible, the game software of each machine is put into tournament mode. Typically, this means that the rules will avoid giving random awards, so that scores reflect mostly skill and not luck. Also, extra balls are disabled if the software supports it. The physical setup of the machines is also configured to make things as challenging as possible. This can be done in a number of ways, for example: Adjusting or removing outlane posts, which make the side drain gaps larger. Increasing the playfield angle (by adjusting the legs on the cabinet). This increases ball speed and makes it more difficult to make shots in the back of the playfield. Making the "tilt" mechanism more strict, allowing less nudging and shaking
