The problem with the casinos in the state of Arizona is that they are very very loosely regulated. IF you are crazy enough to bet max, yeah you might with something worth while but unlikely. It’s very common to see 10% of your spins pay out (if your lucky!) let’s talk about “bonus” spins! On average, you will find an average of 50 cents to a dollar per bonus spin IF YOU ARE LUCKY. You will see lengthy patterns of dead spins with an occasional minimum payout combination. Betting $1.75 per spin, DID NOT win more than what I bet nor made it to the bonus rounds (those in a moment). This morning I tried my luck and put $165 into the Invaders from Planet Moolah. I assure you, these machines are programmed to payout much less frequently on higher bets.
You will notice IMMEDIATELY how the “hold” percentage changes when you increase your bets. Both casinos have horrible returns on slots. Up the highway is it’s sister casino Lone Butte. This casino is a very loosely regulated Indian casino outside Phoenix.
