How do I choose how much to spend on each line? How do I choose how much to spend on each line? You can choose the coin size using the options at the bottom of your game. 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 20p coin size per line and bet on 20 lines you will be spending a total of £4.00 per spin.
