The objective of Onyx Blackjack is to achieve a higher card count than the dealer, but without going over 21. The best hand is Blackjack – when the sum of values of the first two cards dealt is exactly 21. You compete only against the dealer, not against other players.
- Played with eight decks.
- Dealer always stands on 17.
- Double on any 2 initial cards.
- No Double after Split.
- Split initial cards of equal value.
- Only one Split per hand.
- Single card dealt to each Split Ace.
- Insurance offered when dealer shows an Ace.
- Blackjack pays 3 to 2.
- Insurance pays 2 to 1.
- Push game when hands tie.
The game is hosted by a dealer and allows up to 7 players seated at the Blackjack table. The game is played with 8 standard 52-card decks. Card values in Blackjack are as follows:
- Cards from 2 to 10 are worth their face value.
- Face cards (Jacks, Queens and Kings) are each worth 10.
- Aces are worth 1 or 11, whichever is more favourable to the hand. Note that a soft hand includes and Ace worth 11.
After the allotted betting time has expired, the dealer deals one card face up to each player. Dealing starts with the first player to the dealer’s left and continues clockwise, ending with the dealer. The dealer then deals a second card face up to each player but the dealer’s second card is dealt face down. The value of your initial hand is displayed next to your cards.
If the value of your initial two-card hand is exactly 21, you have Blackjack!
If the dealer’s upcard is an Ace, you are given the option to purchase insurance to offset the risk that the dealer has Blackjack – even when you have Blackjack yourself. The amount of insurance is equal to one half of your main bet, and the insurance bet is settled separately from the bet on your hand. The dealer then peeks at the value of his/her downcard to check for Blackjack. If the dealer does not have Blackjack, the round continues. If the dealer has Blackjack, but you do not, the dealer’s hand wins. If you and the dealer both have Blackjack, the game ends in a push and your bet is returned. Note that when the dealer’s upcard is a 10 or face card, you will not be given the option to purchase insurance, and the dealer will not peak at his downcard to check for Blackjack.
Double, Hit or Stand
When the dealer does not have Blackjack upon checking his/her two initial cards, players are given the chance to improve the values of their hands in turn. To enable this the dealer moves clockwise around the table offering to deal further cards to players’ hands.
If the value of your initial hand is not 21, you can decide to Double. In this case, you will double your bet and be dealt only one additional card to add to your hand. Alternatively, you can decide to Hit to be dealt an additional card to add to the value of your hand. You can Hit more than once to receive additional cards before you decide to Stand once you are satisfied with the value of your hand.
If your initial hand is a pair of cards of equal value, you can decide to Split the pair to make two separate hands, each with a separate bet equal to your main bet. After a second card is dealt to both your hands, you can improve the value of these two hands by deciding to Hit. Again, you can choose to Stand once you are satisfied with the value of your two hands. However, if you Split an initial pair of Aces, you will receive only one additional card per hand with no option to Hit .
If the sum of your hand exceeds 21, you bust and lose your bet on that hand.
When all players have taken their turns, the dealer reveals the value of his/her downcard. The dealer must Hit on a hand of 16 or less and must Stand on a hand of soft 17 or more. (Remember that a ‘soft hand’ includes an Ace worth 11.)
You win when the value of your final hand is closer to 21 than the dealer’s hand or when the dealer busts. If the value of your hand is the same as the dealer’s, the game round ends in a push and your bet is returned.
Blackjack is only possible using the two cards in the initial two-card deal. A hand of 21 resulting from a split pair is not considered a Blackjack. Therefore, Blackjack beats any hand of 21 resulting from a split pair.
The Bet Behind feature allows you to bet on a hand dealt to another player. You will share the outcome of the other player’s hand. The payouts for Bet Behind wagers are the same as for ordinary bets.
You can place a Bet Behind bet whether or not you are seated at the Blackjack table and intend to play your own hand. However, you cannot place a Bet Behind bet on your own hand.
Place a bet in any activated Bet Behind spot at another player’s seat while betting is open. Hover your cursor over any Bet Behind spot to view the total number of players who have placed a Bet Behind bet, including the sum of their combined wagers.
If you place a Bet Behind bet, and the player at that seat decides not to participate in the round, your bet will be refunded immediately.
The nickname displayed at each seat at the Blackjack table identifies the player who will make all decisions for that hand. You can, however, decide whether or not to place an insurance bet when the dealer’s upcard is an Ace. You can also decide in advance whether or not to double your bet when the player you are betting behind opts to Double Down or Split.
You can later alter these settings by clicking/tapping the Settings button and then selecting the BET BEHIND tab. You may also untick ALLOW OTHER PLAYERS TO BET BEHIND ME if you wish to prohibit other players from betting behind you.
The Hot Players icon helps you determine which of your fellow Blackjack players is on the longest winning streak.
The number within the gold medal indicates the number of consecutive rounds that player has won. Note that as soon as a Hot Player loses a round, he or she will also lose the gold-medal icon.
The DEAL NOW button is enabled only when you sit at a particular Blackjack table and have placed a bet equal to or greater than the minimum. Click/tap this button to finalize the bet you have placed. Your bet will be visible to other players at the table. The round may begin before betting time expires when all players have clicked/tapped the DEAL NOW button.
