When you sit down for a Bamboo Ways session
Choosing a stake on Bamboo Ways starts with one fact: how often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP version behind the game. An RTP figure describes an average over a very long run, not what happens in your next session.
Checking the RTP starts with the game rules, because the version running on Ignition Casino is shown only there. Six RTP versions exist for Bamboo Ways, each with its own return, so the game name alone does not tell you what you get back.
Deciding how much weight to give the top prize means reading the maximum win as a ceiling. It is a multiple of the bet that the game can reach, and players hit it very rarely. The bet sets the money at that ceiling, and the multiple stays the same. Treat the top prize as a rare outcome.
