So basically, ik that your card value has to be higher than your opponent's in the end, but anything over 21 is a bust and you lose.
So if you have a 21 (jack and 10, queen and 9 or king and 8), you can either tie or win. You can't lose.
I forgot how the dealing works except that you get 2 cards, i haven't played this in 5 years. Don't ask how ik how 2 gamble...
