Bigger Barn House Bonanza keeps one secret until the reels stop
Six scatters bring the free spins, but how often six land is not fixed in advance, and no figure here predicts it. A single session is random from first spin to last: a high volatility rating, a 96.50% RTP and a A$100 stake basis describe the long run, not your next hour or your next round.
Whether the game you open runs at 96.50% return is written in the game rules, not on the lobby tile. Open the rules panel before the first spin and read the return figure and the payout tables there; a different version changes the money you expect back over time.
The x25,000 ceiling sits at A$6,000,000 on the A$240 maximum bet, and reaching it is rare by design. It depends on the SUPER tier inside the Bigger Wheel and a full run of results; treat it as the outer edge of the game rather than a target any session can count on.
