The Game Scenario is loaded by default and touching any of the green squares can result in 2 Outcomes.
The Green Square if its concealing a Bomb, when the finger is lifted, it explodes the underlying Bomb and Reveals all the available Bombs
The Green Square if its not concealing a Bomb will reveal Open Field with a Hint Number to indicate the number of Bombs present in the 8 neighbouring Squares
If the 8 neighbouring squares do not have a Bomb, then the Game Field will automatically trigger opening up all the available Squares, until it hits a Square that could reveal a Hint in each of the 8 adjacent directions
