Blackjack Simulator

A simple Python console application that allows a user to experiment with various blackjack setups and calculate the expected win/loss ratio of one or more players given a particular setup.

The default config lives at configs/default.json and supports the following fields:

• numDecks: The number of decks the dealer is using
• shuffleRatio: The ratio of the original deck size, after which the shuffler will perform a reshuffle of the deck of cards
• players: The set of players to include in the game (the stats of each player will be displayed at the end)
• numGames: The number of rounds to play
• doubleDownEnabled: Whether the double down player action is enabled
• splitEnabled: Whether the split player action is enabled
• ddasEnabled: Whether the double down after split player action is enabled

Sample output after simulation ends:

Player: Alice, winnings: $-99650.0, total wins: 43123, total losses: 47749, total draws: 9128, win ratio: 0.43
Player: John, winnings: $-545500.0, total wins: 41047, total losses: 48566, total draws: 10387, win ratio: 0.41
Player: Timothy, winnings: $-78300.0, total wins: 43119, total losses: 47484, total draws: 9397, win ratio: 0.43
