Overview:

The Layout Editor is a tool for building custom tile layouts for the tile matching game. This feature is only available in the registered version of Pretty Good MahJongg.

The Layout Editor is accessed by clicking on the Layout Editor icon in the list of games (tile matching).

Layouts are comprised of tiles arranged in arbitrary positions on the screen.  Tiles can be immediately adjacent to another tile on any side, including on top or underneath, but they may not overlap.  The editor is capable of producing layouts with as many as 21 tiles side by side, 12 tiles from top to bottom, and stacked up to 16 tiles high.  Layouts may contain up to a full set of 144 tiles.
