Twister only appears on reel 3, when it appears, it expands to cover the entire reel, and all the wins brought by the Twister alternative are tripled. For example, if you happen to not win during the free spin, it will still be a win-win for you, because 100X your bet will be given to you.
The "wind vane" indicates a scatter icon that, when displayed using the "twist" icon, produces a higher payment. The farmer’s and the farmer’s wife are also the highest-paid symbols. The jackpot can also be won randomly after any rotation, win or loss.
