BWT: Blackjack With Trumps

For unknown reasons, you ended up in the house of a man calling himself Lucas. He says that from now on your only goal in life is to entertain him with his game at 21 according to his rules, because there is no way out! In his house there are the same "lucky ones" with whom you have to fight.
The change is that instead of a full deck of 36 cards, there are only 11 with values ​​from 1 to 11 and without suits. The goal of the round is to score a certain number of points, by default 21. Lucas seemed too bored to look at the usual 21. He added the so-called "trump cards". Trumps are given at the beginning of each round and 1 random is rigged into the deck each round. With the help of them you can change the goal of the round, exchange cards with the opponent, get a specific card from the deck, increase the damage done for winning the round, and much more! 28 different trump cards. Play and change the rules of the game as you please!
