# Blackjack

- Terminal version of the classic Blackjack card game written in Ruby. Please note specific house rules outlined on this page

## Overview

- Run the command `bundle install` in your terminal

- To play,  then run `ruby lib/blackjack.rb` in your terminal

- This game supports multiple players: currently it is set to one player vs. a dealer

  - To add more, utilize the `add_player` method in the `blackjack.rb` file and save your changes before running the game

  - Reference the commented out `add_player` invocations at the bottom of the file as an example

## Testing

  - Written in RSpec

  - To test all at once: run command `bundle exec rspec`

  - To test individual spec files:

    - run, for ex: `bundle exec rspec ./spec/dealer_spec.rb`

## House Rules

- Each player starts with a bankroll of $1000

- Each round begins with players entering their bets

  - The minimum bet is $2

  - The maximum is equal to the current value of the players bankroll

- The deck is shuffled prior to each round

- 2 cards are dealt to each player and the dealer from a standard deck of 52 cards

  - The dealer's 2nd card will be face down until the players complete their turns

  - An ace counts as a 1 or 11

  - Face cards are 10 and any other card is its pip value

- The dealer will always hit until the value of their hand is >= 17 points

- Players play against the dealer - multiple players can win

  - If a player's hand is not busted (over 21) and has a higher score than the dealer, the player will receive their bet double at the end of the round

  - Otherwise, the player will lose the amount they bet (ties with the dealer are considered a loss)

- Bets are reset after each round

- If a player goes bankrupt, they are out of the game

- Rounds are unlimited and the game is only over when all of the players go bankrupt (in this case, when they can't afford the minimum bet of $2)

#### Ruby Concepts (personal use)

- RSpec

  - Unit Testing

    - Test doubles

    - Cases where the `dup` method is vital

    - `respond_to` for checking if variables are exposed

    - When to use context block

  - Integration Testing

- `send` method

- `colorize` gem

  - `background` argument for rendering cards

- Freezing constants

- Overriding `==`

- Overriding `to_s`

- Class inheritance

- `product` method - to create a deck of cards

- splat operator - to return cards to deck w/out nested arrays

- `shift(n)` method
