Rule presets

Australian

This rule preset is an example of Mah Jong as it is often played in Australia, New Zealand and Papua New Guinea. The most distinctive feature of this rule preset is the generous paying to losers (though a ready hand is required), which encourages collecting of valuable hands. 

As in the modern American Mah Jong, the winning hand may have only 1 Chow and must not contain mixed suits. Several other non-classical features are used as well: the use of Goulash deal after a draw, the elimination of the Dead Wall and melding of the Flowers and Seasons face-down.
Tiles 144 (Flowers and Seasons)
Initial points 2,000
Limit points 1,000
Restrictions for the winning hand Prohibition of mixed suits (except in Limit hands requiring mixed suits and certain other Limit and Special hands), Maximum number of Chows 1 (except in Limit hands and when the hand is fully concealed)
Claiming rules for going out Pung precedes Chow and Chow precedes a pair
Passing of the deal When non-dealer wins
Rule of Ready None
Dead hand rules None
Payment Between all players; Chinese Classical
Discards In random order, no extended discard information
Specialties Goulash deal after a draw, no Dead Wall, melding of Flowers and Seasons face-down, rules for competitive claims
Scoring  
Basic tile points Standard. Losers are paid the same as the winner.
Scores for basic sets Standard. Losers are paid the same as the winner.
Scores for Flowers and Seasons Standard. Losers are paid the same as the winner.
Scores for patterns based on Chows None
Scores for patterns based on Pungs and Kongs None
Scores for patterns based on the whole hand Fully concealed hand (2 dbl), Chow hand (0/10* pts; must be fully concealed, since more than 1 Chow is allowed only in a fully concealed hand; in addition, no value pairs are allowed), Pung hand (1 dbl), All Odd (100% of Limit/3 dbl for losers), All Terminals and Honors (3 dbl, Pung hand implied); One suit with Honors (1 dbl), One suit only (3 dbl). 
Note: * indicates scoring for the pattern in a concealed hand. If separate scoring is not given, ready losers are paid the same as the winner (the loser's ready hand is considered fully concealed if it is ready and contains at least two Chows, since only one Chow is permitted in an exposed hand).
Scores for miscellaneous patterns 2 points for making a Pung or Kong from East's first discard. Losers are paid the same as the winner.
Scores for winning Otherwise standard, but Out on the last discard is not acknowledged: Winning (20 pts), Self-drawn last tile (2 pts), Out on a one-chance Chow (2 pts), Out on a pair (2 pts), Out on the last tile of the Wall ( 1dbl), Out on a supplement tile (1 dbl), Out by robbing a Kong (1 dbl).
