I believe it’s single value/advance with flipper up and double value/advance with flipper down during the build phase (awesome risk/reward here). So if you’re hitting loops in the build phase with the flipper down i believe it’s adding 500k/million/1.5M instead of 250k/500k/750k (flipper up). Flipper position doesn’t appear to matter during the jackpot phase - I was wondering if that was gonna change.
Side note - pitch seems to drastically effect the loopability on this game. The steeper ones I’ve played are much harder to loop.
