I remember when penny slots were introduced and the majority of them were 9 line. so. a person could sit and actually bet .09 per flip and play quite a while on a $20. More and more I am seeing only 30+ lines on penny machines. So if I am betting .30 per flip or even .40 per flip would I be better off playing the quarter machines? I like the penny machines and the cute bonus's and sometimes I can double my money betting .30 per flip. But, the odds makers say the odds are better on quarter machines. Just seems like the penny machines are getting pretty pricey.
