Megajacks is an exciting and unique online video poker option that offers a mega jackpot. Based on the game of jacks you have the chance to win life-changing amounts of money when you bet the maximum in this online casino game.

How to Play Megajacks

When you begin playing Megajacks you will need to place a bet by clicking on the Bet One or the Bet Max buttons. Be aware that unless you bet with the maximum number of coins you will not be eligible for the progressive jackpot.

Click on the cards you want to hold and then click on the Deal button again. The cards you did not hold will be replaced by new cards to create a new five-card poker hand. Your hand will be assessed and you will be paid out for any winnings. If you achieve a royal flush while playing with the maximum number of coins, you will be awarded the progressive jackpot.

If you win, you will be able to collect your winnings immediately or to gamble your winnings in order to double or half double them. The computer will select a card from five face-down cards and you will select another card. If your card ranks higher than the computer’s card, your winnings will be doubled or half doubled. If your card ranks lower than the computer’s card, you will lose your winnings for that round.
