If you are trying to limit the bet, you can choose to reduce the payline. You can also set the value of the coin to 0.01 to 20.00, the maximum bet is 100.00, and the minimum bet is 0.01.
If you want to play high, the maximum bet button will save you manually scrolling and will automatically set the bet as high as possible. However, this will start the reel to rotate directly, so don't click this option unless you are sure. If you like the idea of autoplay without having to click every time, check out the autoplay feature.
