So given the numbers, what games should you consider playing to potentially get the biggest bang for your buck? The lowest casino win percentage among slot machine denominations  and thus the highest win percentage for players  is for nickel slots.

Pick Slots With The Highest Return To Player (RTP) Percentage. If you're looking for slot machines that are most likely to hit, a good starting point would be finding ones that have the highest percentage of RTP. This is because the higher the RTP percentage, the more likely the slot machine is to pay out.
