Knowing the payout percentage of the slot machine, you can roughly understand how much of the money you spent on the game will return to you after some indefinite period of time. Slots payout percentages is an indicator that expresses the percentage of your bets placed to your winnings. If there is any truth in this, it makes sense to always play at the highest stake and accept sometimes play time might be short depending on bankroll.First, I would like to clarify what slots payout percentages is. To me logically the RTP % paid on different stakes is to ensure the slot takes the same amount of profit in a given time period no matter what the stake. Presumably the impact of lower RTP on slots mainly paying base wins and regular low value bonus games will be be more noticeable than slots with potentially high value bonus games where it is mostly about the volatility of getting the bonus game. Not really sure how the RTP are calculated, I'm assuming lower RTP results in less wins in the base game and less bonus games being triggered (or lower wins in the bonus ). The RTP on the base game is truly rotten on many slots especially those with potentially high paying bonus games. Sometimes premium play is 94% not that premium play is a good choice, as despite RTP advantage premium play often seems the fastest way to lose money. The best one I can find is 777 Burn em up, which is still at 95% across all stakes (although it doesn't seem to translate into a profitable session in my experience). Some of the older slots still have higher RTP but they are becoming rare.

There have been murmurings on the forum about the gradually lowering of RTP's in the online casino's as well as the bookie/arcades.
