Four Winds Mah Jong 
for Pocket PC

The interface resembles much the interface of the desktop version but due to the portrait orientation the tiles must have been arranged a bit differently. 

Note the toolbar buttons: tap the Save button to quickly save the game, the Wall button to display (and hide) the Wall window (e.g., to check the deal number, wind of the round, etc.) and the Pause button to pause (and resume) the game.

Note: The size of the screenshots is 50% of the original size.
