21 Dice Game 🎲

Another burdensome homework from OOP Theory class (the sigh is real). Hopefully I'll learn something useful.

📄 Description

Design a game as following:

Number of players: 4 (always). If < 4 players are playing, the program will automatically added a number of players so that there are 4 of them.
There are 4 dices. Each dice has the probability of a face of 20%, and the remaining outcomes are 16%: For dice number 1-4, the face with 1-4 dots is the one with 20% possibility.
Each player has:
- Name
- Total accumulated points
- For virtual players: Have different ways of expressing game over (say something nice, leave game, silently do something bad...)
There is 1 game master who:
- Decide who will go next;
- Calculate the points for players:
  - If previous turn's accumulated point + this turn's point = 21: Winner. End game.
  - If previous turn's accumulated point + this turn's point > 21: Point = 0;
  - Otherwise: add points as normal
- Announce the winner. Virtual players express their disappointment differently.
At each player's turn, they will receive at random a dice and roll it.
