Triple Sevens is a blackjack game with a unique side-bet; one which gives us the chance to win an accumulated progressive jackpot. Each time a player plays this game and loses a hand, the money lost goes to an overall prize pool, which continues to grow until it is won. The jackpot has no upward limit, so it can grow in excess of a hundred thousand dollars. Aside from the side bet, the game plays much like classic blackjack. As this title is a progressive jackpot game, no free/practice version is available.

In order to be eligible to win the overall jackpot, a compulsory side bet of one dollar (in addition to your regular blackjack wager) is required in the designated area of the virtual blackjack table; this side bet is usually automatically placed. A hand of three Sevens of Diamonds (for a total of 21), will win you the progressive jackpot. Other combinations which include a Seven will also net you an increased return, so you don’t have to get three Sevens of Diamonds in order to win big.
All other regular blackjack rules are as follows:
One thing you must never do if playing Triple 7s Blackjack, is split a pair of Sevens. Splitting Sevens in this game was actually originally one of the eight deadly sins, punishable by death, but it was later removed and simply deemed an act of pure stupidity. In all seriousness, you should follow basic blackjack strategy, apart from when it says to split a pair of Sevens.
In order to qualify for the overall jackpot, or any other of the smaller jackpots, your Sevens must be in the same hand. Receive two Sevens of any kind and you’ve already won a jackpot. Make sure you then hit in order to gain the chance at drawing another magical Seven.
The house edge of Triple Sevens Blackjack needs to be calculated in accordance with the overall jackpot: the starting figure is 37.94%, less 3.45% for every additional $10,000 which has accumulated in the progressive jackpot meter. The jackpot would need to reach or surpass a total of $109,860 for the house edge to be withered down to zero, and while it is rare for it to reach such heights, it is certainly not impossible, and even a jackpot of around $60,000 offers an enticing house edge for a side-wager.
