William Hill Casino, one of the reputed online blackjack game portals, recently announced that it had upgraded its game offerings. In an effort to attract more blackjack players to its website it has released brand new blackjack game called 21 Duel Blackjack. In addition, to the new blackjack games, the William Hill Casino also has a few new slots games out this October as well.

This exciting blackjack variation is very much like a classic game of blackjack but has its own quirks and features. The game of 21 Duel Blackjack is played against the dealer and the player has to try to get a hand value that is higher than that of the dealer’s hand without exceeding a total of 21 points.

Players will have to start the game off by placing an ante and then a side bet; the side bet is an optional feature in the game of 21 Duel Blackjack. The game begins when the player clicks on the “deal” button on the game screen at the William Hill Casino. Players will be given 2 cards to start the game – one will be face up and the other will be face down. The dealer will also be given 2 cards; however, both of these will be face down. After this, 2 community cards will be dealt to be used by the player or dealer.

Find what changed in the game

New blackjack products often change a particular part of the familiar game: an extra wager, a different decision, more hands or a new interface. The announcement is useful for identifying that change. It is not a substitute for a complete rules sheet, nor proof that a named product remains available.

Main game
Identify the basic format and who or what the player faces.
Extra feature
Separate optional bets and paid choices from the ordinary wager.
Missing detail
Do not infer an unreported payout, rule or current availability.
Does a new feature automatically make the main game better value?

No. A feature describes a change, not its mathematical value. Start with the full rules and any separate wager or fee; the linked rules and odds guides explain what to compare.
