Rule variations 
Special tiles  Transparent tiles
In Japan (and occasionally elsewhere) a special kind version of Mah Jong, 
inspired by the popular anime Akagi, is sometimes played, where three of the 
four tiles sets are replaced with transparent tiles. While there are no 
established rules yet, Four Winds lets you experiment with this game style by 
allowing you to specify up to 4 sets to be replaced with transparent tiles, and 
also specify whether transparent tiles are shown in the Wall (normally the Wall 
tiles are hidden when transparent tiles are used).
To use transparent tiles in the game:
  - Choose Preferences on the File menu.
 
  - From the Rule Presets list, choose a customized rule preset.
 
  - Choose General under the Rules section of the category
    tree.
 
	- Click Other button to show the Other Special Tiles dialog 
	box.
 
  - From the Transparent Tiles group, specify the number of transparent tiles 
	sets (from 0 to 4).
 
	- Check Transparent jokers if you wish to use transparency in 
	jokers. When checked, all jokers used in the game will be transparent. The 
	option can also be used without specifying any tile sets to be transparent.
 
	- Check Mirror when in hand if you wish to show transparent tiles 
	mirrored (like when playing in real world) when they are turned down (e.g., 
	when they appear in another 
	player's hand).
 
	- Check Show in the Wall if you wish to show the transparent tiles 
	in the Wall
	(in 
	real game the Wall tiles are normally hidden when transparent sets are 
	used). When this option is checked, you can view the tiles in the Wall and 
	Dead Wall (when applicable) in the Wall window by right clicking 
	anywhere within the window (right click again to toggle with the views). The 
	transparent tiles are shown face up and opaque tiles face down.
	Note: The wall tile view of the Wall window is refreshed each 
	time you toggle the view so that the first tile of the view is the next 
	available tile in the Wall. 
Note: 
The patterns All opaque and All 
transparent (under Sets & Patterns > Miscellaneous patterns) become 
available when using transparent sets.
