You don’t have to think hard about slots payback in many cases. Most games are roughly the same in terms of RTP. The only factor that you really have to consider is whether you are in a land-based or online casino. Online slots have steadily increased in payback ever since they were first launched in the mid- 1990s. Most internet slot machines released today deliver anywhere from 95% to 97% RTP.
Obviously it’s still nice to know the exact payback. This information can be found by googling individual game developers followed by the word RTP or payback. But you can roughly assume that most internet slots offer anywhere from 95-97% RTP. Land-based slots developers don’t publish payout percentages. But they often group payback based on coin denominations.
