The Second Rule: Denominations Do Not Pay Equally Reports show that penny slots generally offer the worst payouts, while high-limit machines like $25 slots tend to offer the best payouts. Interestingly, while $100 machines might seem like they should offer bigger wins, they don’t always do so. This discrepancy could be due to several factors, including gambler behavior or the rarity of these high-limit slots. So, do higher denominations pay more than lower denominations? Yes, but there are caveats. Slot developers typically provide several payback options for casinos to choose from. Since the payback percentages don’t always correspond to the denomination range, some slots with lower bets can have similar payback rates to higher bet slots. The key takeaway here is that casinos often set higher payback rates for higher-denomination slots. So, if you’re aiming for bigger rewards, your investment will need to be higher.
