The paytable lists the theoretical return at 96.50% for the base game, every Ante Bet tier and each Buy option, so none of the switches in Big Bass Football Bonanza moves the documented return. What they move is cost and timing: the price of a spin, how you enter Free Spins and how quickly the balance turns over.
Raising the stake with Ante Bet
Turning this toggle on raises the price of every spin before it changes anything else. The 15x tier loads extra Scatter symbols onto the reels, 16x instead gives each Free Spins round a repeat chance once it ends and 25x stacks both. RTP stays listed at 96.50% for all tiers, the Scatter increase is never quantified and, while any tier runs, the Buy options stay disabled.
Paying to skip the trigger
Three purchases sit side by side in the base game: 100x the total bet triggers a regular Free Spins round at once, 180x does the same with a repeat chance attached and 300x goes straight into Mega Free Spins, which otherwise needs five Scatters. The paytable lists 96.50% RTP for each. The repeat is only a chance, resolved after the round it follows.
Sizing the total bet
The total bet is the unit everything is priced in: line wins, the Money symbol values stated as multiples of it, the 5000x win cap and the cost of every purchase all scale together, while the documented RTP stays 96.50%. The record gives $0.20 to $250 as the limits but flags those figures as not fully verified on the captured screens, so confirm them in the bet menu.
Setting the pace of play
A speed button cycles normal, quick and turbo spins, holding SPACE turbos one spin on demand and Autoplay can skip the feature screens. Evidence ties these switches to tempo alone: they set how many spins fit into a minute, and so how fast the balance moves, with no documented effect on what a spin returns. Autoplay counts beyond the captured 100 are unconfirmed.
