Session results and feature timing
96.51 is the RTP of Big Bass Reel Repeat, and it describes a return over a very large number of spins, not any single session. How often the Free Spins round comes is not known in advance. Each spin is random, so one session can include a long quiet stretch or a sudden run of bonus rounds, whatever the RTP says.
The 96.51 figure is the RTP this page reports. Which RTP version is live is shown only in the game rules, so read those before the first spin. Figures on this page are a guide to the design of the game, not a promise for any single session.
5,000x the bet is the maximum win of Big Bass Reel Repeat. At the A$5 example bet that is A$25,000, and at the A$500 highest bet it is A$2,500,000. Reaching that ceiling is very rare, and a round ends as soon as the total win hits it.
