Blackjack Basic Strategy

What the program does

Play Blackjack with your friends (locally) right on the terminal!

Each time a move is made, the program will let you know if the decision you made is the correct one, according to the Blackjack Basic Strategy chart.

Demonstration

Basic round: demo.gif

Just like in real life, you can split your cards: demo2.gif

Blackjack rules

  • You can hit and stand as long as you haven't bust
  • You can double down only in your first hand
  • You can split your cards (4 splits max [This is fairly standard])
  • Dealer stops at soft 17
  • You can ask for insurance if the dealer has an ace (No insurance is offered with a 10)
    • Insurance is worth half your bet
  • If the dealer has Blackjack, play is suspended (If a player did ask for insurance, they'll be rewarded)
  • There's no surrender (Although it could be implemented)

How to install

Just clone the repository and run:

TODO:

  • Make it so that the program takes into account the running/true count, in order to practice Card Counting
    • This shouldn't be too hard to do

Asterisks:

1: This is the first time I write anything in C. The code isn't the cleanest. I'll probably refactor stuff later on. There are messy things in the source code. I just wanted to finish it

  1. Enjoy ^_^
