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

Scenarios:

1. Add Player

   If there is no participant
   the user writes: "add player Pippo"
   the system responds: "players: Pippo"
   the user writes: "add player Pluto"
   the system responds: "players: Pippo, Pluto"

2. Duplicated Player

   If there is already a participant "Pippo"
   the user writes: "add player Pippo"
   the system responds: "Pippo: already existing player"

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"
   the user writes: "move Pippo 2, 3"
   the system responds: "Pippo rolls 2, 3. Pippo moves from 6 to 11"

As a player, I win the game if I land on space "63"

Scenarios:

1. Victory

   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"

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"

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"

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

   If there is one participant "Pippo" on space "3"
   assuming that the dice get 1 and 1
   when the user writes: "move Pippo"
   the system responds: "Pippo rolls 1, 1. Pippo moves from 3 to 5, The Goose. Pippo moves again and goes to 7"

2. Multiple Jump

   If there is one participant "Pippo" on space "10"
   assuming that the dice get 2 and 2
   when the user writes: "move Pippo"
   the system responds: "Pippo rolls 2, 2. Pippo moves from 10 to 14, The Goose. Pippo moves again and goes to 18, The Goose. Pippo moves again and goes to 22"

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:

1. Prank

   If there are two participants "Pippo" and "Pluto" respectively on spaces "15" and "17"
   assuming that the dice get 1 and 1
   when the user writes: "move Pippo"
   the system responds: "Pippo rolls 1, 1. Pippo moves from 15 to 17. On 17 there is Pluto, who returns to 15"
