Jacks or Better 50 Play Power Poker differs from standard video poker in that you play fifty hands of cards at the same time.

Take note that a complete deck of 52 cards is used for each hand. Furthermore there are no wild cards and the maximum payout is 4,000 coins. The minimum amount you can bet in each game is $2.50 and the maximum amount is $125. You can vary the coin denomination after each game depending on what you feel. The minimum coin denomination you can play with is 1 cent and the maximum is 0.50 cents.

The number of coins you bet with is also variable. For example, you may want to spend some time playing with 2 coins per game and then switch to playing with the maximum 5 coins per game. Payouts begin when you get a hand of ‘Jacks or Better’ – the best hand you can have is a Royal Flush and if you achieve this you get the maximum payout of 4000 coins providing you have bet the maximum 5 coins.
