Swedish Blackjack rules
If the player is closer to 21 than the dealer he wins as much as he bet, except when he has a blackjack, that pays 3:2.
You have blackjack when the first 2 cards equals 21. That would be a dressed card / 10 and an ace.
The player may take as many cards as he wants to until he gets 'bust' except when he has split 2 aces, then he is only allowes one more card. If the player has 21 he may draw more cards but not if he has blackjack.
The dealer has to draw to 16 and stay on 17. Blackjack beats 21.
If the bank has A,6 it is 17, while the player can choose,7 or 17.
At 17,18,19 the bank wins if it's a tie.
At 20,21,BJ it's a 'stand off' if it's a tie.
Stand off means the player neither wins or looses, he keeps his bet.
If the player doubles on 9/19 och get a 2 it totals 11 because he doubles on 9 because double at 19 isn't allowed.
Insurance and even money
Actually the insurance pays 2 times the insurance bet and you lose the bet but it even out; exception below.
If the dealer doesn't get blackjack the bank takes the insurance bet and the game continues as normal.
If the player has blackjack and the dealer gets an ace as his first card the player is offered 'even money' which means that the player then gets his money payed out immediately but only 1:1. So he doesn't get the usual 3:2 for a BJ but he doesn't risk to not win at all in case the dealer gets a BJ.
The reason for even money is this;
Imagine you have blackjack and wants to insure it, say you're playing for $10 The insurance bet is then $5. Two things might occur:
Dealer gets BJ: You keep your $10 plus $5 from the insurance, and win $10 on the insurance, result: +$10
Dealer doesn't get BJ: You keep your $10, lose the $5 from the insurance, and win $15 from your BJ, result: +$10
Even money also means +$10. Even money is just a more simple form of insurance.
Over / Under 13
If the player bet under 13 and get 2 aces it pays 3:2, otherwise he's paid 1:1 if he wins.
Odds for over / under (not verified);
13: 8,28 % , Over: 46,7 % , Under: 45,0 %
So if you'r not a card counter avoid over / under.
Differences in rules
In most international places it's a stand off at 17,18 and 19 too. That the dealer wins a ties at 17,18,19 is a mayor disadvantage to the player.
International it is a common rule that you'r only allowed to split aces once.
You are not allways allowed to double after a split, giving the bank more advantage.
Double might only be allowed on 9,10,11 or 10,11. Some places you can double at any two cards, which gives an increased chance of winning.
