Sushi Go

This is a work-in-progress conversion of Sushi Go (original), the popular card game by Gamewright into Ruby.

The long term goal is to make it easily scriptable via a RPC-interface that hooks into something as described in my ideas repo.

Currently only supports the original game, and not Sushi Go Party. The following features are supported:

  1. Scoring of individual rounds and final scoring (desserts)
  2. Setup for 2-5 players
  3. Chopsticks are supported, using the extra sushi go call
  4. Pick-and-pass

There are rigorous tests for the scoring algorithms as well.

You can find the complete rules at the gamewright website.


Add this line to your application's Gemfile:

gem 'sushigo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sushigo
