here is what i learned. u can always go down in price, but going up again is harder. i mean in regardss to rbion vs acdc pricing, its obviousy that acdc is a more expensive pin so u would ask more per play. also i would think acdc is kinda a bigger attraction so people might play it more even if its higher priced...

in regards to the em, i never tried ems on location since down here they are just crazy expensive and i dont really know how to work on them. not a dick move at all to ask a higher price for 5 balls compared to 3, thats kinda what i do with older games like system 11 u ask more for 5 balls, cause the game will get more wear that way. i think 5 balls for 25 cent is abit too low maybe.

okay here is a tip ill share cause i mean why not... turn match feature off. reason average people who might play it and who are clueless might not even know what it does and will just walk away.
also i found the percentage to be way off point on bally/williams. i once set the match to the lowest possible on a fish tales and it gave away matches way too often when me and my friend played a couple of games on it to test it. almost so that i figured wow something must be wrong with this game lol.

also make sure your replay scores are achievable but not so easy that anyone who can play decently can get free games without having to work for it. i myself like getting a free game when playing on location it feels good, but when u operate them dont make it crazy easy todo so. maybe check audits each month to see how many free games are achieved (i should do this myself more often), if its crazy high adjust it to a higher margain.
