*** HOW TO PLAY ***
The tiles can be swiped horizontally (from left to right and vice versa) and vertically (from up to down and vice versa).
Two adjacent tiles are added when they came in touch generating a new tile: 3 x 3 = 9 (new tile).
You win when the tile 177147 is reached and you lose when no addition is allowed between adjacent tiles.
