About us

JD Supplies & Services is an independent provider of live table games. We focus on the delivery of exciting side bet games that are a step-change above ‘legacy’ side bet games. These are designed entirely from the player perspective, which usually is not the case.
Game concepts and intellectual property associated with these games are typically protected by patents, trademarks and copyrights.
We are delighted to introduce our 7JACK side bets for Blackjack and FAT card games.

Our advantages

Keep it easy

Pay a fixed fee per table per month.

The price remains the same no matter how many side bets you wish to add on your table, exchange them whenever you want.

Our graphic designers can customize your layouts to your wishes.


All our games are tested by BMM Testlabs or GLI . Evaluation reports against GLI-11 are available on request.

Unique features

All of our games can be explained in less than 20 seconds and have some unique features.

Twins & Crazy Twins:
First side bet ever that is directly related to the Blackjack game. No other game can pay that much for getting a pair.

Higher 7*:
Get a 7 and win 3 to 2, as a Blackjack hand! Interesting in combination with Twins & Crazy Twins....

Get the Picture*:
Excitement until the end of the Blackjack game! Each time a player has 2 picture cards, he has a chance of winning the bonus! The excitement builds up until the dealer’s second card is turned!

*Please note that these games are also available with the special number 8 in stead of 7 for your Asian players.
