The Goose Game Kata

Goose game is a game where two or more players move pieces around a track by rolling a die. The aim of the game is to reach square number sixty-three before any of the other players and avoid obstacles. (wikipedia)

This kata has been invented by Matteo Vaccari, you can find the original slides here.

This is a variation of the original Goose Game Kata I use for Clean Code Classes.
