Caribbean 21 is a blackjack variant which offers the player the ability to split any two initial cards and to hit and redouble after doubling. Of coruse nothing is ever free and the player loses all ties. There are several other rule changes from blackjack so read carefully before playing. Following the basic strategy below the game offers a house edge lower than most blackjack games.
Caribbean 21 Rules
- The game is played with eight regular 52-card decks.
- All cards are valued as in blackjack, except an ace is always one point.
- Play starts with the player making an initial wager.
- The player shall receive two cards face up and the dealer one
card face up. The dealer does not take a hole card.
- The player may hit, stand, double, split, or surrender. The
hit and stand option are the same as in conventional blackjack.
- The player may double at any time with two or more cards. This
includes redoubling and doubling after a split.
- Splitting is allowed on any two cards. Aces have no special
restrictions as in blackjack and have the same splitting rules as
other cards. After the player splits, each single card hand in
turn shall immediately get an additional card.
- The player may surrender at any time. If the player surrenders
he forfeits half his total bet at that time. Surrender is allowed
after splitting on a hand by hand basis.
- An ace and two 10-point cards is called a "Caribbean 21" and
is ranked higher than all other 21 point hands, including after splitting.
- The dealer shall win all ties.
- A winning player bet shall pay even money, except for a
Caribbean 21 which pays 3-2 on the initial hand only.
- If the dealer's up card is an ace then the player may take
insurance against the dealer having a Caribbean 21. Insurance may
be taken at any time and for any amount up to half the total bet
at the time insurance is taken. Insurance shall pay 9 to 1 if the
dealer does get two 10-point cards as the second and third cards.
The insurance bet shall be adjudicated at the end of the hand. The
player may also add to the insurance bet at any time, so that the
total insurance bet does not exceed half the total wager.
