Welcome to Blackjack! The version implemented here is one-deck
casino blackjack. Since there are so many rule variations out there,
the detailed rules are spelled out here.
To start, input the number of players. Each player starts with 100
chips. Use the slider to place your bets and click New Hand to deal.
The bet has to be an integer amount. If a player has less than 1
chip, he will be topped up with 100 chips. A player's chip count and
win/loss are tracked.
In Blackjack, the objective is to win by creating card totals higher
than those of the dealer's hand but not exceeding 21, or by stopping
at a total in the hope that dealer will bust. Number cards count as
their number, the jack, queen, and king ("face cards" or "pictures")
count as 10, and aces count as either 1 or 11 according to the
player's choice. A total of 21 on the first two cards is a "natural"
or "blackjack."
The players and dealer will be dealt two cards. All players will
receive their hands face-up. The dealer will receive the first card
face up and the second card face down. The dealer peeks at the
second card if the first card is an ace or ten-value card but only
reveals it if it makes the dealer's hand a blackjack.
If the dealer has blackjack:
-
All players with blackjack tie with the dealer and their bets are
returned to them.
- All players without blackjack lose their bets.
-
The hand is over, and players can place their bets again for the
new hand.
If the dealer doesn't have blackjack:
-
All players with blackjack win and receive a payout at 3:2 odds,
or 1.5 times their bet.
-
All players without blackjack will take turns, starting from the
player first dealt. On each turn, the options available are:
-
Hit. The player will receive a card from the top of the
deck.
-
Stand. The player ends their turn and play continues
with the next player.
-
Split. This option is only available when the player's
hand has two cards and if the starting two cards have the same
rank. The two cards will be separated into two hands and one
card each will be dealt to them. Play proceeds as normal.
Further rules on splitting below.
-
Double down. The player doubles their bet, and receives
a single card. This option is only available when the player's
hand has two cards.
-
Surrender. The player gives up half their bet and
forfeits their hand. This option is only available when the
player's hand has two cards.
-
If a player busts upon hitting or doubling, the player loses his
bet.
-
Once all players have finished their turn, the dealer reveals his
face down card. If there are still remaining players, the dealer
draws cards if needed until the hand achieves a total of 17 or
higher. The dealer never doubles, splits, or surrenders. If the
dealer busts, all remaining player hands win. If the dealer does
not bust, each remaining bet wins if its hand is higher than the
dealer's, loses if it is lower, and ties if it is the same.
-
The hand is over, and players can place their bets again for the
new hand.
Rules on splitting:
- Re-splitting not allowed.
- Hitting split aces allowed.
-
A ten-value card dealt on a split ace (or vice versa) will not be
counted as a blackjack, but simply as 21 points.
- Double down and surrender after split allowed.
