If you don't know what Yahtzee is you don't need goffel.
Goffel includes a library, which implements the game logic of Yahtzee, as well as some game implementations.
To install goffel just run:
go get muhq.space/go/muhq/goffel
Goffel has a command line utility to start the various game interfaces.
goffel -hA game on a goffel server instance can be played simply through netcat.
> netcat muhq.space 63036
HELO test
test
h
The above example connects to the goffel server running at muhq.space.
It registers a player, named "test", joins the session "test" and outputs a help message.
An example how to use goffel's library can be found in uis/interactive.go. It implements a simple terminal based yahtzee game.
