Description

From the listing uploaded by “catappult”.

The aim of this game is to teach you the fundamentals of BlackJack which is the American variant of a globally popular banking game known as Twenty-One. When you start the game, you will have 100 score, see how much you can make in one sitting, the game will save your high score. If you lose all your score, you will have to start the game again. The next time you play, you will be able to try and beat your highest score from the previous sitting. The game is played between the dealer and the player, the dealer will deal two cards to the player and two cards to the dealer - one card being visible to the player and the second card will be face down. The player will then have the options: Hit - which will give the player another card. Stay - means you are satisfied with your current cards and it will then be the dealers turn. The aim is to beat the dealers card values. The dealer must draw to a minimum of 17. If the dealer or the player go over 21, they will bust. If the dealer and the player draws the same value, the house will win. Card values: Ace - 1 or 11 Jack, Queen, King - 10 Cards 2 - 10 is equivalent to their value - 2-10. BlackJack Twenty-One will be receiving updates from South Side Game Studios which will include new features.
