A round table in a boathouse with three rivals, the stock, the pile and a hand of raised cards

What it solves

The gap

Shedding games are mostly luck, so simple computer players all feel the same.

What it is

This template gives the weaker rivals visible habits and lets the strongest deal out the unseen cards and test every choice, which measurably wins more deals.

How you use it

Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.

Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.

Who it is for

Use it when

  • Publishing a shedding card game such as Crazy Eights, Uno-style or Mau-Mau with computer opponents.
  • Learning how a complete Crazy Eights card game is built in plain JavaScript and Canvas 2D.
  • Building a branded mini-game for a client.

Built for

  • Web and indie game developers who know some JavaScript.
  • Developers who want a finished, tested game to build on instead of a blank canvas.

What you get

One engine for everyone

The deal is plain data with pure functions for legal cards, play, draw and pass, so the table, the rivals, the look-ahead rollouts and the test bot all use exactly the same rules.

Looking ahead over hidden hands

The best rivals deal the cards they cannot see to the other seats, keeping away suits a player was seen to lack, play each legal choice to the end of the deal many times and keep the one that scores best.

No build step

Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.

A smoke test

A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
