Shanghai Pocket Essentials 1.0
the author of this app says:
This game is similar to the Mahjongg. The object is to match up tiles and clear the board. Create your own layout or choose one of the supplied schemes. You are allowed to create layouts with five levels. There are two different levels of difficulty, and you can play with either 24 or 36 tiles. The graphics for this game are good, too.
This program requires Palm OS 2.0 or later.
