Well, from what I understand, the game chip itself dictates how many credits the max bet is, so your stuck on how many credits you play. BUT, you can change your accounting denomination. So for example, let’s say each credit is worth .25 cents on a game that has a max bet of 3 credits, so your total bet could be .25, .50 or .75. You can change it so that each credit it worth whatever you’d like. Let’s say $5. So then your bets would be $5, $10, and $15 respectively. You would have to change the sticker in the glass from .25 cents to 5 dollars. (If you wanted to. You don’t HAVE to)
To change this on a machine you need a clear and a key chip. And those are determined by what type of MPU you are running in the machine.
