Mahjongg is a single player game that probably originated in Asia. Whilst simple in concept a good deal of strategy is required to complete the layouts.
The objective of the game is to remove all the tiles from a layout in the least possible time. Layouts can vary in pattern, size and shape. Tiles are removed in pairs and may only be removed if they are both free and match one another. Free tiles are ones that have no other piece touching the left, right or both sides and no tiles on top.
