When does the bonus round actually arrive?
Choosing to start a session on this slot means accepting that nobody can say when the bonus round will appear. Free Spins, Wheel Bonus and Bigger Wheel depend on symbols landing at random, so a quiet stretch and a busy one look identical. The RTP describes the average over a very large number of rounds, and a single session can finish well above or below it.
Picking a version to play starts with the game rules, because they show which RTP this lobby runs for the title. Open them in the game before your first spin, and check that the RTP there matches the figure shown on this page. Do not rely on a listing you find elsewhere.
Deciding how much weight to give the top figure means reading it as a ceiling, not a target. The top prize is reached very rarely, and the highest figure only comes from the top tier of the Bigger Wheel. Plan a session around your own budget and keep the win figure in perspective.
