Othello

Othello is a kind of black-white chess game for two players. In this app, the other player is phone AI.
Othello is played on 8 x 8 squared board.

Start:
+ When new game begins, each player places two discs (Black chess vs White chess) on the board.
+ The discs should be placed on the board`s four central squares.

Move:
+ A player places a disc in a vacant square so that in at least one direction (vertically, horizontally, or diagonally) his newly-placed disc,
acting in conjunction with a pre-existing disc of his own color, brackets in an unbroken line one or more discs of his opponent`s color.
The disc or discs thus bracketed are then turned over or “flipped” to become the same color as the newly-placed disc.
If a newly-placed disc produces bracketing in several directions at once, then all the bracketed discs in all such directions are flipped.
+ Take turns to play a piece
+ A player without a move simply passes, and the other player keeps playing pieces until the first player can make a move again.
+ The objective is to have more of your colour face upwards at the end of the game.
+ The game is over when neither player has a legal move or when the board is full.

Level:
+ Select difficulty between 1 to 8.
