Let’s start with the basics. You may already know that each slot comes with a promoted Return to Player (RTP) value. This is the amount the game is promoted to return to the players in forms of wins over a period of time. Slots have different RTP values, depending on the game in question. You can come across a slot with an RTP value of 92%, which is considered to be low, while another game can have an RTP value of 99% which is considered to be high. So when faced with a dilemma among two games with these RTP values the natural response would be to go for the one with the higher RTP value. But this is not necessarily the case when it comes to real play.
Many experienced players refer to the RTP value simply as a guideline that the slot can pay more frequently in a long session. But other factors like the slots variance and the Random Number Generator (RNG) affect the outcomes on the reels. So a high RTP slot can eat away a huge chunk of your balance just as easily as a low RTP slot would. High RTP slots are mostly used by experienced players when it comes to wagering a huge bonus amount. In this case the player has a bigger chance to clear a big part of the wager, without his balance taking a big hit. This is due to the high RTP value which usually produces frequent, but smaller payouts.
