Play by navigating to the bin folder and executing:

java mineSweeper.main.MineSweeper

Game Mechanics

• You can uncover a field using the left mouse button, it then shows the amount of neighboring bombs. If it was a bomb you lose and the game ends. If it does not have a neighboring bomb, all the neighbors are uncovered as well (recursively).
• If you think there is a bomb in one field, you can use the right mouse button to mark it. When it is marked it cannot be uncovered, but you can remove the mark by clicking the right mouse button again. If you uncovered all the fields without bombs, you win the game.

Picture 1: The View of a running game with 10x15 fields and 15 bombs. Marked fields have a "!".

Model-View-Controller-Pattern and Observer-Pattern

I implemented the game using the Model-View-Controller-Pattern. The game and all the game mechanics are in the model containing the classes game and field. The controller contains all the controls and sends them to the model. The view creates the visuals using Swing and is also an observer of the model so it can change the view depending on the changes in the game. The Observer-Pattern is implemented using java.beans.PropertyChangeSupport.

Execution

1. Navigate to the bin folder.
2. Play by executing:

java mineSweeper.main.MineSweeper

Which creates a default game with 10x10 fields and 10 bombs.

3. Or try your own combinations of sizes and bombs by using
   java mineSweeper.main.MineSweeper (x_dim y_dim (number_bombs)).
   This could for example result in

java mineSweeper.main.MineSweeper 5 15

which creates a game with 5x15 fields and 5*15 / 10 = 7.5 ~ 7 bombs,
or in

java mineSweeper.main.MineSweeper 10 15 15

which creates a game with 10x15 fields and 15 bombs
