I discovered one of my all-time favorite games back in my Commodore 64 days: Mah Jongg from Nels Anderson. Mahjongg is a 2,000 year old Chinese game where you must match sets of tiles in an attempt to clear the board.
Versions for Windows Mobile devices are not new but Amazing Mahjongg from Thinking Thing Software looks quite promising with polished graphics and 26 custom layouts.
Amazing Mahjongg is available for $9.95 USD from our affiliate Pocketgear. A trial version is also available.
