This Mahjong game is not common. This is in three dimensions, inspired by Egyptian theme, and in order for the pieces to disappear, you must find three equal ones instead of the usual two. You will get it by turning it and making sure that the selected chips are not blocked by other chips.
Play with your mouse and always combine 3 identical pieces to throw them out of play. The stones must have at least 2 free adjacent sides. You can rotate your view. Finally, click "End Game" and then "Submit Game" to save your high score.
