Don't expect a set pattern for bonus rounds
Three or more Money symbols start Hold & Spinner, and three or more Scatter symbols start Free Spins, on the 5x3 grid. How often either one lands is not known in advance. Every spin is random, so one session can bring several bonus rounds or none at all. The result of one session is random whatever the RTP version.
Each spin on the 5x3 grid runs on one of two RTP versions. Which version 888 Casino runs is shown only in the game rules. The version decides the long-run return, so the rules are where to look before the first spin.
Landing the best combination on the reels can pay up to x10,000 of the bet, and that ceiling is reached very rarely. At an A$5 bet the ceiling is A$50,000, a limit and not a plan for any session. Read it as the highest possible payout, never as an expected one.
