Czech Blackjack (mobile)

The goal of the game is to achieve a combination of cards with the highest possible sum of point values.
The player with the highest point total wins.
At the same time, however, the total point value of the cards in the player's hand cannot exceed the number 21.
The point values ​​of the cards are as follows: cards 7-10 keep their values, jack and queen are worth 1, king is worth 2 and ace is worth 11.
Seven of hearts has variable value - 1, 7, 10 or 11.
A special case is the situation when the player receives two aces at the very beginning of the game, which in this case have a combined value of 21.
In a tie, the dealer always wins, unless the player has exactly two aces.
Czech Blackjack allows you to exchange cards for certain combinations. In this case, you will be notified by the dealer.
