Solver

The solver uses backtracking. It is able to solve puzzle games based on rectangular board, where the player has to deduce missing digits. The most known game is the Sudoku for example.
You only have to update the "Main" class with the grid you would like to solve. Set "-1" for empty cell.
Two ways of displaying are available: through console of through JFrame. See the DisplayStrategy interface.
To solve another Game, you only have to extend the abstract class GridValidator. The solver will manage the rest.
To sum-up: the solver needs to know the game name (see GameName enumeration), the board inputs, and the displayStrategy. That's all.

You know this game. :-)
