Details

• This application is a simple Fifteen Game.

• The "board" is made from 16 buttons. The "empty space" is a white button with no text.

• The pieces that player can move are buttons with text from 1->15.

• When a player clicks a button, we check:

  • All it's neighbours on 4 directions: North, South, East and West.
  • On a matrix those positions would be:
    • x + (1,0)
    • x - (0,1)
    • y + (1,0)
    • y - (0,1)
  • We ignore those who go out of bounds ( bigger than matrix size or negative values )
  • If we find a neighbour that has no text this is our empty button, and the current button will switch places with it.

• All buttons positions are saved in a List so we can check if they are in order. If the list is sorted, the game is over.
