The reason I like Betsson is because the games they have are very nice and will only time out if you stop playing for a while. Unfortunately, players from the US can't play for money.
Cherry Red Casino is also very good when it comes to playing blackjack. They offer a special blackjack bonus that is a 200% bonus and worth up to $1200. The special bonus is a play bonus and can't be withdrawn.
My other favorite place to play for fun is Golden Palace. They have flash casino that you can play for fun. Golden Palace has my favorite BJ game - Blackjack Switch
Some tournaments are won by posting the highest score in X number of hands, like 50 hands or so or after a certain amount of time. Others are elimination style tournaments where the lowest player at the table after a round is removed. Both are pretty fun and gaining in popularity.
Pontoon
How to Play
You can play up to three hands at a time. To bet, click on a chip denomination in the lower right corner and place it in one of the three rectangles. To remove a chip, click on the chip with an X on it and click on the chipstack. Press deal when you to get your cards.
Pontoon is a very unusual variant of blackjack and it can be confusing to play if you have never done so before. The rules are very important in this game and they directly figure into making moves you would not normally make in any other blackjack game. That being said, it is a very fun version to play and has some benefits not seen in other games.
What make Pontoon different?
Well lets start out with the obvious. You don't get to see either of the dealer's cards. This means you essentially playing against yourself. The dealer will check for a Pontoon, which is what the blackjack is called in this game.
The big rule in Pontoon - you must hit (called twisting) if you have a total of 14 or less in your hand. I have a strategy to the right for what to do when you have 15 through 21.
Pontoons pay 2 to 1 on bets, as opposed to 3 to 2 in normal blackjack. Also if you get a 5 card trick, meaning you hit three times, you also win 2 to 1 on your bet.
The big exception (and most frustrating part of the game) is rule number 2 - the dealer wins all ties. This includes Pontoons and 5 card tricks. If you get a 5 card trick, the dealer gets to draw to try to match and beat your hand.
Another big rule that you need to know is that you can double down (called Buying) at any time during the hand. After you double, you can hit again (in fact you have to if your total is 14 or under).
