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.

http-server from root directory. That's it.

The simulation can be run headless from the command line. Run

I hand-coded a few AI strategies to test against the human opponent. Descriptions below. You can find the code in player-strategies.js.

Each turn, buy a province if you can afford it. Otherwise, buy gold or silver. If cannot afford either of those, buy nothing.

Same as "Big Money", but buy Duchies near the end.

• 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
