 *  DESCRIPTION: 'FailCaffè' is a game designed by Francesco "Ciccio" Granato.
 *  The goal of 'FailCaffè' is to decide who, among n people, will brew coffee.
 *  Each player has 3 dices: a tetrahedron (4 faces), an octahedron (8 faces) and a dodecahedron (12 faces) and 3 shots.
 *  During each shot, the 3 dices are rolled and the player can choose which of the 3 dices to keep, possibly none.
 *  When a dice is chosen, its value is added to the player's points and the dice cannot be kept again in the next roll.
 *  The final player's score is given by the sum of all the kept dices' values.
 *  In the final roll, all the remaining values are added to the player's points anyway.
 *  Dices names are {ID12, ID8, ID4, NONE}. If names are written in lowercase, an exception will be thrown.
