|Four Winds is by far the most customizable Mah Jong in the world.
In addition to supporting over 20 pre-defined rule presets, you can
create and save any number of customized rules. To use an existing
rule preset as a template, first choose that preset from the Rule
presets list, then choose "Customized". Here the Hong
Kong rule preset is used as a template and a value of 2 faans
is specified as the minimum for the winning hand. By clicking the Exceptions
button you could specify e.g., whether the points for Flowers
and Seasons should be ignored when determining if the hands meets
the minimum point requirement.
To save the customized rules as a user-defined rule preset, click
the arrow button on the left of the Rule presets list and
choose Save As New Rule Preset.
