You can play blackjack in the taverns. Look for a sign with a mug on it and that building is a tavern. In Tortuga, there is one tavern in the town and the other close to Fabiola. The Faithful Bride is in town and the King's Arm is outside of the town. However, the best place to play any kind of poker is Padres Del Fuego. It has the highest buy in so you can make more money faster---that is if you know how to play and lady luck is on your side! Blackjack is also called '21' because you want to get your cards to equal 21, or get as close as you can to it. All the cards have their face value (5 = 5, etc.) except for the face cards (queen, jack, king ace) queens, jacks, and kings are worth 10 and an ace is worth either a 1 or an 11 depending on your hand. Each hand you are dealt only two cards. If your two cards equal 21 (jack and a ace, etc.) you have "blackjack". If they don't equal 21, then you have two options to 'hit; or to 'stay'. Hit means you want an additional card to get closer to twenty one. Keep in mind that if you were dealt two cards that equal 15 and you 'hit' you have a good chance of 'busting' (going over 21). It is best to stay when you have been dealt 14+, although you can always try your luck. I hope this helps. For more information on how to play blackjack, visit this site
