The coin size is the amount you'll be betting on each line. It's important because each win is based on a multiple of your coin size. Playing on more lines increases your chances to win and enter bonus rounds, as there is a higher chance that the symbols fall on a line that you're betting upon. The coin size is then multiplied by the number of lines that you are betting on. If you decide to bet with a 20c coin size per line and bet on 20 lines you will be spending a total of €4.00 per spin.
