I mostly play penny slots when I go to Vegas. My largest wins have been on penny slots. However why does it seem like I win more doing max bet on a penny machine at 2.00 a spin then when I bet on a quarter machine were the max bet is .75 a spin? I mean I know I'm betting more with each spin but I always thought the higher denominations payout more. I'm definitely a low-roller and usually spend just a couple hundred per day in the casino. Any tips or advice? Stick with penny machines at max bet or go to nickels or quarters? I do enjoy all the fun bonus rounds that lots of the penny machines have.
