Minesweeper: Blueprint description

My take on the classic Minesweeper game.
Play in three different sizes of hexagonal boards.

Each board is created so that:
1- The first tile you select will never be a mine.
2- The board always has a deducible solution, so no guessing is ever required.

This is my second project meant to be an exercise for the complete development and deployment of an android application.

Hope you enjoy!

Any and all feedback is appreciated.
