- Players receive two cards face up, while the dealer only receives one card face up. There is no hole card.
- Players may hit, stand, split, surrender or double.
- Players may double at any time. This includes redoubling and doubling after splitting cards.
- Surrender is available at any time. In the event the player surrenders, half of the total bet is forfeited.
- Splitting is permitted on any two ties.
- The dealer wins all ties.
- If a player is dealt an Ace and two 10-point cards, the hand is called a “Caribbean 21” and is ranked higher than all the other 21-point hands. A Caribbean 21 pays 3 to 2. All other winning hands pay 1 to 1.
