Unknowns in Bigger Bass Splash play
Choosing a stake on Bigger Bass Splash means accepting that Free Spins can come on any spin or not at all. How often they come is not known in advance. The result of one session is random, whatever the RTP of 96.50 says about the long run.
Before you set a stake, read the game rules, because they are the only place that shows which RTP version is running. This page cannot state that version for you. Read the rules before the first spin, and keep the RTP figure in mind as a long-run reference, not a result for one session.
Treating the top prize as a plan would be a mistake, because the maximum win of Bigger Bass Splash is a ceiling that is reached very rarely. It stands at 5,000 times the bet, which is A$50,000 at the A$10 example bet. The ceiling describes the highest outcome the game can pay, not what a session tends to pay.
