There are a few differences between Live Dealer Mega Ball and Online Bingo. You're not playing against anyone else. You don't have to be first to complete a line to win. All cards are in play until the last ball has been drawn. All completed lines count towards your payout. There is no payout for a Full House. Not enough balls are drawn to complete a card. The total number of balls, 51, is significantly lower than standard Bingo, which normally starts with 75 Balls. Once you've purchased your online mega ball cards you can change the numbers on them until betting time closes. There is no Jackpot prize in Mega Ball, only enhanced payouts due to the multipliers.
