Creating and managing custom rule presets

Guidelines for customizing rule presets

Please keep in mind the following when you customize the rules:

Several of the rule options and scoring items depend on each other: in order to be able to change the setting of one option you sometimes need to first enable another option. E.g., to assign a scoring value to Flowers and Seasons in loser's hand, you need to check the Flowers and Seasons box on the General page (under the Rules section in the category tree of the Preferences dialog box) and make sure that the equivalent winner's scoring item has already been assigned a scoring value.
Certain rule options are mutually exclusive: e.g., you cannot use Dora tiles together with Jokers.
Certain rule options automatically include other rule options. E.g., enabling Dora tiles enables the dead hand rule according to which declaring of the fourth Kong (or fifth, if all four Kongs have been declared by the same player) during the deal results in an abortive draw (this is because the 5th tile of the Dead Wall is the first Dora tile and cannot be used as a supplement tile).
Four Winds checks the logic of some but not all settings. To avoid conflicting rules and confusion in the point calculation it is recommended that you use a predefined rule preset as a template for your own rule preset and make only minor adjustments to the rule and scoring options.
Unusual rule combinations may result in computer players playing poorly. Strongly customized rules are most suitable for multiplayer games.
