Before the opening round, bonus timing stays hidden
Deciding how long to stay on Elvis Frog in Vegas starts with an unknown: when the bonus round lands. Nothing before the first spin shows how often Free Spins come, and the RTP does not show it either. Every session is random, so one run can end well above or well below the RTP. Each figure on this page describes the long run, not the evening you have.
Choosing a stake is one decision; checking the RTP version is another. The RTP version that Milkyway Casino runs is shown only in the game rules, so check it there before the first bet. Read that line before staking, not after.
Setting expectations for the top prize starts with one fact: it is a ceiling, not a target. Elvis Frog in Vegas caps a round at a fixed multiple of the total bet, and that ceiling is reached very rarely. How often it comes is not known in advance, and no session shows it.
