A python package to run all of the necessary elements of a Craps table. The package follows some natural logic:
CrapsTable
has Player
(s) and Dice
on itPlayer
(s) have Bet
(s) on the CrapsTable
as prescribed by their strategies. With these building blocks, crapssim supports
These powerful options can lead to some unique analysis of the game of craps, such as the following figure comparing 4 strategies with a budget of $200:
I will post results from this simulator on my site: http://pages.stat.wisc.edu/~kent/blog.
Current blog posts include:
You can install crapssim with
pip install crapssim
This requires Python >=3.6 and pip to be installed on your computer. You will also need a recent version of numpy, which can be installed by pip install numpy
.
There's a few good resources for getting started:
To see how a single session might play out for you using a pass line bet with double odds, over 20 rolls, one might run:
import crapssim as craps
table = craps.Table()
your_strat = craps.strategy.passline_odds2
you = craps.Player(bankroll=200, bet_strategy=your_strat)
table.add_player(you)
table.run(max_rolls=20)
To evaluate a couple of strategies across many table sessions, you can run:
import crapssim as craps
n_sim = 20
bankroll = 300
strategies = {
"place68": craps.strategy.place68,
"ironcross": craps.strategy.ironcross
}
for i in range(n_sim):
table = craps.Table()
for s in strategies:
table.add_player(craps.Player(bankroll, strategies[s], s))
table.run(max_rolls=float("inf"), max_shooter=10, verbose=False)
for s in strategies:
print(f"{i}, {s}, {table._get_player(s).bankroll}, {bankroll}, {table.dice.n_rolls}")
For more advanced strategies, you need to write a custom function that can perform the strategy. Some building blocks and examples can be found in strategy.py
