While it is a common belief that higher denomination slot machines pay out more often than lower denomination machines, there is no hard evidence to support this claim. Slot machine payouts are determined by a random number generator, and are not influenced by the amount of money that is wagered. This means that the chances of winning are the same whether you are playing a penny slot or a dollar slot. That said, higher denomination slots typically have higher payouts for winning combinations, so players may win more money in the long run by playing these machines.
