RTP or “Return to Player” is the payback ratio. The WORST were early gameking games like Blowfish and a few others at 84%. The typical RTP is 93-95% and even better. A lot goes into the RTP. Each “Reel” has 64 stops, the number of paying legends/combinations times the number of reels equals the “RTP”. Some machines make it easy to stay in play for quite some time. Example…. Double/triple wild cherry. You can have a cherry ANYWHERE in the window and get your bet back. Your not going to get wealthy this way…until you hit the THREE double or triple cherries ON THE PAYLINE and max bet, But you get to try for a lot longer.
