One of Zach’s best friends cashed in a 9bil snack bar at Pinburgh last year and the game was voided 
“Due to the complex and imperfect nature of pinball machines, rare and / or unusual scoring situations may arise that are the unintended consequences of programming oversights, errors, mechanical issues, or wiring issues. If a tournament director deems a player is taking advantage of an unexpected scoring situation or an obscure “programming bug”, the tournament director reserves the right to warn the player in question to not abuse the situation further, end the game in progress at the current score, award a score of zero, or ask the player to restart the game. The determination of whether a player is taking advantage of a software or scoring issue and the subsequent penalty, if any, is left up to the discretion of the tournament director and will be based on the particulars of the specific situation.”
