Fully-customizable blackjack simulation.

Setup

Clone the repository and install locally via pip.

pip install .

Usage

Begin by setting up the Blackjack class object with certain house rules.

from blackjack import Blackjack

blackjack = Blackjack(
    min_bet=10,
    max_bet=500,
    s17=True,
    blackjack_payout=1.5,
    max_hands=4,
    double_down=True,
    split_unlike_tens=False,
    double_after_split=False,
    resplit_aces=False,
    insurance=True,
    late_surrender=True,
    dealer_shows_hole_card=False
)

Next, create each player that will be added to the table. There are several different card counting systems (both balanced and unbalanced) available for each CardCounter and BackCounter class instance. Player class instances do not count cards.

from blackjack import Player, CardCounter, BackCounter
from blackjack import CountingStrategy

player1 = Player(
    name='Player 1',
    bankroll=1000,
    min_bet=10
)

player2 = CardCounter(
    name='Player 2',
    bankroll=10000,
    min_bet=10,
    counting_strategy=CountingStrategy.HI_LO,
    bet_ramp={
        1: 15,
        2: 20,
        3: 40,
        4: 50,
        5: 70
    },
    insurance=None
)

player3 = BackCounter(
    name='Player 3',
    bankroll=10000,
    min_bet=10,
    counting_strategy=CountingStrategy.HI_LO,
    bet_ramp={
        1: 15,
        2: 20,
        3: 80,
        4: 120,
        5: 150
    },
    insurance=10,
    partner=player2,
    entry_point=3,
    exit_point=0
)

Finally, add all players and simulate.

blackjack.add_player(player=player1)
blackjack.add_player(player=player2)
blackjack.add_player(player=player3)
blackjack.simulate(penetration=0.75, number_of_shoes=1000, shoe_size=6, seed=1)
