I am pretty sure you already know this game. You have to pick up two equal looking tiles and build down the pyramide of tiles. Mah Jongg for Windows is a Shareware game by Ron Balewski. Even if it is a little "old fashioned" it still is fun to play. In this package you will find 3 medieval looking tiles: Medieval.tis, Pirates.tis and Oldengl.tis. There are also two DOS-Programs included to let you preview the tiles and to make your own tile-set.
THE Mah Jongg CORNER http://www.surfari.net/~jimgray/download.htm you will find many helpful utilities for tile sets and some lists with descriptions of those V0*.tis files.
Last but not least you should visit the authors homepage to get more great software from him http://www.microserve.com/~ronb/mjwin1.shtml

Have fun!
