A bare-bones simulator and visualizer for the card game Dominion in JavaScript. Simulator can be run headless from command-line with node.js or in the browser. Visualization powered by React.
Currently only supports standard cards. Card descriptions can be found here.

Strategies
I hand-coded a few AI strategies to test against the human opponent. Descriptions below. You can find the code in player-strategies.js.
Big Money
Each turn, buy a province if you can afford it. Otherwise, buy gold or silver. If cannot afford either of those, buy nothing.
Smart Big Money
Same as "Big Money", but buy Duchies near the end.
Smart Duchy
- always go for province when you have 8
- always go for duchy when you have 5
- always go for smithy when you have 4
- always go for silver when you have 3
- go for gold when you have 6, if there are 4 or more provinces
