Blackjack

Rules

• You have 1 hour for the assessment. Do not worry if you do not complete all the assessment; finish as much as you can.
• Descriptions of each method to implement are written into the lib/ files. For each lib/ file, there is a corresponding spec/ file.
• Run the specs as you solve the assessment. Solve the assessment in this order:

rspec spec/deck_spec.rb
rspec spec/hand_spec.rb
rspec spec/player_spec.rb
rspec spec/dealer_spec.rb

• Wait until you finish to run rspec spec, which will run all the tests. Do this as a final check that you have them all passing.

Game Rules

• Players play against the dealer; multiple players can win each round.
• Players win if they don't "bust" and either:
  1. their hand is worth more points than the dealer's hand.
  2. the dealer busts.
• To compute a hand's value, add the value of each numbered card, and ten for face cards. An ace is worth 11 if the total score would be <= 21. If an ace value of 11 would result in a bust, it is worth 1.
• A score of >21 is a bust.
• Players are first dealt two cards; they can request additional cards ("hit") until they pass ("stay") or bust.
• The dealer must hit on a hand worth <17, otherwise he must stay.
