Here, you can choose to set only 0.15 from each rotation, one coin on each of the 15 paylines, or you can raise it to the upper limit of 300.00. If you want, you can set the reels to rotate faster, and the auto function lets them rotate themselves as many times as you wish.
The game randomly selects a Mystery Scatter from any of the standard symbols. If this becomes part of the winning combination, all other symbols on the same reel will become more examples of it, which will result in some substantial rewards.
