SupaJax is a Video Poker game which is a modified version of Jacks or Better. The SupaJax game adds an additional card to the deck, the ‘SupaJax’. This card does not help any hand other than 4 Jacks, where if the SupaJax is the fifth card the game pays out the progressive jackpot. The basic changes to the Jacks or Better paytable – other than the SupaJax payout – are a reduction of the Royal Flush, Full House and Flush payouts.

SupaJax is only available at Microgaming casinos;

Some notes on the table below;

- We’ve included both the 5 coin House Edge and the House Edge when playing 1-4 coins. The House Edge for 1-4 coins are the same and as such only one figure is listed. To find the house edge/paytable for 2-4 coins just multiple the 1 coin figure by the number of coins.


Microgaming 5 coins 1-4 coins
4oaK Jacks with SuperJax 16416-61533 0
Royal Flush 3000 250
Straight Flush 250 50
4oaK 125 25
Full House 35 9
Flush 25 6
Straight 20 4
3oaK 15 3
2 Pairs 10 2
Jacks or Better 5 1
House Edge (-1.67%)-6.26% 9.27%

* The paytables for 2, 3 and 4 coins are just the paytable for 1 coin multiplied by the number of coins. The House Edge for 1-4 coins are all equal at 9.27%.

* Microgaming documentation lists the House Edge for SupaJax as 9.57%. This House Edge could only be achieved if the 4oaK Jacks with SupaJax payout was reset at 0 and the player used a general Jack or Better strategy rather than a strategy optimized to the jackpot size.

* The negative house edge value indicates that the player has an edge over the house when the jackpot reaches a certain point. The breakeven point for this game is a jackpot of 52400 coins or $52400.
