Quoted from DirtFlipper:For Gottliebs that use the standard Credit Unit (not the half-moon style), it's a really simple, reversible mod to set it up to:
a) be on free play; and
b) reset to 0 credits at each game start, regardless of how many have been won during a previous game (up to the max of 15 or 26, depending on the type).
This is exactly why you can't skip over any of the threads here in the EM Hangout. You never know what you might discover.
I'd really like to learn about this!
