Adjust your stake per spin with the interface controls, then press spin to start a base game round. Raising the stake scales cash returns linearly on a winning combination, but it does not change the underlying probabilities or RNG trigger rates. No stake size buys better odds here.
Autoplay is available with a selectable spin count, and it stops automatically when a bonus feature triggers. Where operators expose loss, win and time limits inside the autoplay panel, setting them before you start is the single most effective control available in the game client. It takes about ten seconds.
Because the jackpots are fixed multipliers rather than progressive pools, changing your bet changes the cash value shown above the reels for each jackpot tier. It does not change the probability of reaching them. Worth remembering when a bigger displayed Mega figure starts looking like a better chance.
