Football rules give you the opportunity to participate in the Dollar Ball jackpot. Just click the enable button just below the Dollar Ball jackpot. Then you can choose five numbers, or the game can randomly select them at random. Clicking "Activate" will confirm your number selection. Each time you play a round of "Football Rules," the number you draw will appear above the number you choose. The bonus amount will be awarded to you whenever a number matches your choice. When all the numbers match the drawn numbers, the jackpot is your bonus. You can disable the jackpot game at any time.
