Two dimensional array.
Render each subarray from bottom to top.
Place each piece in the start of the array.

Let user choose from a button above each row where to place a chip.

Keep count of player names and colors, maybe with some text input.
objects.Player has name and color.

Turn + Events

Width = 7, Height = 6

Check from each block of a color (maybe keep track of blocked pieces for effectiveness).
Maybe allow for custom combinations required to win.

Class with info about player <- passive
- name
- color (of token)

Interface for a player's actions <- active
- Methods for throwing token into column.
- +Info

Input/Output
- Input interface
 * int getNextColumn(objects.Player p); //Retrieve user input
- Output interface
 * void displayBoard(board.IBoard b);
 * void displayMessage(String s);

 Random Events
 - Interface events.IRandomEvent
  * void act(board.IBoard b);
  * String announcement();

events.IRandomEvent
Abstract events.RandomEvent implements events.IRandomEvent (void flipCoin // Does something if heads)
Shuffle extends events.RandomEvent

objects.GameObject
objects.Token
 Owner instanceof objects.Player

GameObjects(objects.Token, empty)
 * One class
  * getColor();

Winning Conditions
 - Interface events.IWinCondition
  * boolean hasWon(objects.Player p, board.IBoard board);


 "Main" method (Game)
 - Outer loop: "While the game has not been finished"
 1) Determine who's turn
 2) Get next input: int j = input.getNextColumn(p);
 3) Execute move: p throws in column j.
 4) Check if p has won.
 5) Update view (output.displayBoard())
 6) events.RandomEvent.act();
