You will use 5 reels and up to 30 paylines, which you can adjust using the toggle button at the bottom of the screen. You can use as few paylines as you want, and you can adjust the numbers frequently without penalty. In addition to the payline, you can increase the amount of each coin from 0.01 to 1.00 and provide up to 10 coins per line.
The total bet is calculated by multiplying the value of the coin by the number of coins per line and then multiplying by the number of valid paylines selected. But don't worry that you don't need to solve this problem for yourself, because there is a box that shows your total bet. If you want to take risks, the gambling function may be of interest to you. It is only available when you win, and you can choose to gamble instead of collecting it. You will play a simple guessing game where you can take a higher bonus. But if you fail, you will give up everything you gamble.
