Shockwave is a Video Poker game which is a modified version of Jacks or Better. The basic changes to the Jacks or Better game are that when you receive a 4 of a Kind the game enters bonus mode. For the next ten hands, or until you receive another 4 of a Kind, the 4 of a Kind payout is increased to the same payout as a Royal Flush.

For ease of comparison, the below table displays the best House Edge for Five Aces available at each software provider;

Software 5 coins House Edge
GamesOS 2.66%

Online we’ve only found Shockwave Video Poker at casinos using GamesOS software. The paytable we’ve seen is displayed below;

Some notes on the tables 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.

Straight Flush 500 100

Flush 40 8
Straight 25 5
3oaK 15 3
2 Pair 5 1
Jacks or Better 5 1
House Edge 2.66% 6.88%

* 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 6.88%.
