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)

As a player, I want to add me to the game so that I can play.

As a player, I want to move the marker on the board to make the game progress

Scenarios:

1. Start

If there are two participants "Pippo" and "Pluto" on space "Start"
the user writes: "move Pippo 4, 2"
the system responds: "Pippo rolls 4, 2. Pippo moves from Start to 6"
the user writes: "move Pluto 2, 2"
the system responds: "Pluto rolls 2, 2. Pluto moves from Start to 4"

If there is one participant "Pippo" on space "60"
the user writes: "move Pippo 1, 2"
the system responds: "Pippo rolls 1, 2. Pippo moves from 60 to 63. Pippo Wins!!"

2. Winning with the exact dice shooting

If there is one participant "Pippo" on space "60"
the user writes: "move Pippo 3, 2"
the system responds: "Pippo rolls 3, 2. Pippo moves from 60 to 63. Pippo bounces! Pippo returns to 61"

4. The game throws the dice

As a player, I want the game throws the dice for me to save effort

Scenarios:

1. Dice roll

If there is one participant "Pippo" on space "4"
assuming that the dice get 1 and 2
when the user writes: "move Pippo"
the system responds: "Pippo rolls 1, 2. Pippo moves from 4 to 7"

5. Space "6" is "The Bridge"

As a player, when I get to the space "The Bridge", I jump to the space "12"

Scenarios:

1. Get to "The Bridge"

If there is one participant "Pippo" on space "4"
assuming that the dice get 1 and 1
when the user writes: "move Pippo"
the system responds: "Pippo rolls 1, 1. Pippo moves from 4 to The Bridge. Pippo jumps to 12"

6. If you land on "The Goose", move again

As a player, when I get to a space with a picture of "The Goose", I move forward again by the sum of the two dice rolled before

The spaces 5, 9, 14, 18, 23, 27 have a picture of "The Goose"

Scenarios:

1. Single Jump

7. Prank (Optional Step)

As a player, when I land on a space occupied by another player, I send him to my previous position so that the game can be more entertaining.

Scenarios:
