Hot runs before do not warm the next spin
Each spin stops the five reels at random, and the bonus round can come on any spin. How often it comes is not known in advance. One session can bring many triggers or none, because the result is random whatever the RTP. The RTP only describes the average over a very large number of spins.
The reels never show which RTP version is running, because that information sits only in the game rules. Check the rules before you choose a bet, and compare what they say with the figure in the table above. A different version would change the long-run return, so the rules are the place to confirm it.
Very few spins reach the maximum win of Elvis Frog in Vegas, so treat it as a ceiling, not a target. Reaching it needs the right symbols on the right reels during a round, and no one can plan for that. Set each bet at a level you can afford to lose.
