How to play

The objective of the game is to get a hand total of closer to 21 than the dealer without going over 21. The numeral cards 2 to 10 have their face values, Jacks, Queens and Kings are valued at 10, and Aces can have a value of either 1 or 11. The Ace is always valued at 11 unless that would result in the hand going over 21, in which case it is valued as 1.

After you place a bet the dealer then deals you two cards face up. The dealer also gets two cards – one face up and another face down. You have several choices to continue the game.

Stand – If your first two cards are acceptable, you can stand.

Hit – If you would like more cards to improve your hand total, the dealer will deal you more cards, one at a time, until you either bust (go over 21) or you choose to stand.

Double – If you have a hand total that is advantageous to you but you need to take an additional card you can double your initial wager and the dealer will deal you only 1 additional card.

Split – If you are dealt a pair (2 cards of equal value) you have the option to put out a second wager and the dealer will split the two cards so that each card will become the first card on two new hands. You will be dealt a second card on each hand and can play each hand one after another.

Insurance – Insurance is a side bet offered when the dealer has an Ace as an up-card. You can put up a wager equal to half your original bet, which will get paid 2 to 1 if the dealer has a Blackjack.

If your hand has not busted, then it is time for the dealer to play their hand. The dealer will first flip over their “hole card” (the face down card) and add up their 2-card hand. If the dealer has a hand total of 17 or higher, they will automatically stand. If the dealer has a hand total of 16 or lower, they will take additional cards until they either bust or get a hand total of 17 or higher.

Provably fair

When you open the game page the server generates a secret and a seed and reveals its hash (using HMAC SHA256 algorithm). The server secret represents randomly shuffled card deck. The server seed is a cryptographically secure random alpha-numeric string. The hash of these 2 strings helps to ensure that the initial card deck is not altered after you choose the bet amount. After the game is finished the server secret and the server seed are revealed, so you can easily calculate and verify the hash.

When you play a game you can pass an extra custom string – client seed (if it’s not specified a random number is automatically generated by your browser). The server will then calculate another hash using the server secret, the server seed and the client seed. The last 5 chars of this hash (representing a hexadecimal value) will be converted to an integer. The result number will be divided by 52 (number of cards in the deck) and N cards will be cut (moved from the top to the bottom of the deck), where N is the remainder of the division. Because the client seed can not be predicted by the server the number of cards cut from the initial deck is completely random and hence you can be sure that the game result is fair.
