This is all you need to know if you wish to play:
The croupier deals you two up cards and one to himself. Now you are interested in your card total, which should be as close as possible to 21, but without going over. If it is not close enough yet, you can draw additional cards (tap with your fingers on the table), but you had better stop early enough, so that you will not go bust (wave your hand horizontally if you do not wish another card). In any case you must draw until your total is 11.

What happens when ... (for more advanced players):
 • ... Your first two cards are an ace and 10 (or a face card)? Congratulations, you have a Black Jack and are paid 3 to 2! But if the croupier also has one, it is a tie and you get your wager back.
 • ... The croupier’s up card is an ace (possible Black Jack)? You can take insurance by placing another bet on the insurance line (at least 1/2 table minimum and not more than 1/2 of your initial bet). And then? If the croupier has a Black Jack, you lose your initial bet, but win double the amount of your insurance. If the croupier does not have a Black Jack, you lose your insurance and win or lose your initial bet - depending on who is closer to 21.  • ... The croupier’s up card is an ace, 10 or face card (possible Black Jack), while you have a Black Jack? You can ask the croupier to pay your initial bet 1 to 1.
 • ... Your first two cards are of equal value (e.g. two 8’s or jack & queen)? You can split them (you have to match your initial bet), which means that you are dealt additional cards on each of these two cards, until the total is close enough to 21 (or you go bust) - this is basically ordinary Black Jack, except that two games are played instead of one. And if you happen to be dealt another card of equal value (e.g. another 8)? You can split them again. An exception is when you are splitting two aces. In this case you are entitled to a single additional card for each ace. What about if you have split two aces and then draw a 10 or vice versa (if you have split two 10’s and then draw an ace)? Sorry, this is not a Black Jack. It is only a 21, which is not too bad.
 • ... Your cards are good, while the croupier’s are not (or you feel lucky)? You can double down your initial bet (even after splitting cards) and you will be dealt one additional card.

What value do single cards have?
Aces are counted as 1 or 11 (you decide), face cards equal 10, other cards hold their face value.
