Before You Spin, the Parts Nobody Knows
Pragmatic Play publishes 96.71% as the return across millions of spins, which says nothing about the order of those spins. Free Spins can land on your first press or stay away for a whole evening, and no schedule exists for either. Each session is a fresh set of random results, so a page can describe the bonus, never promise when it arrives.
Pragmatic Play builds Big Bass Splash with more than one return setting, and the one in front of you appears in the in-game rules panel, not on the lobby tile. Check that figure before staking A$2 or A$5, because a lower setting shrinks the share returned over a long run while leaving every spin random.
The x5,000 ceiling is real as a cap, near-zero as an expectation. Reaching it needs the best fish values combined with WILD collectors and a high multiplier level all in one round. Treat A$25,000 at A$5 a spin as the outer edge of what the game allows, not a target a session works toward.
