British Official

The British rules (as laid out by the British Mah-Jong Association) are a sort of a mixture between European and Australian rules. As Australian rules, they use Flower and Season tiles, limit the number of Chows to one (but unlike Australian rules, without allowing exception for a fully concealed hand) and apply a Goulash deal with jokers and Charleston after a drawn deal. Also, losers are rewarded for having a calling special hand. 

But as in the classical rules, the British rules do not prohibit mixed suits. British rules require an obligatory ready declaration before going out a feature that is often used by players in Nordic Countries (especially Sweden and Finland), as well. The selection of scoring patterns is fairly classical, but a couple of new patterns and special hands are added, and some common patterns and limit hands (notably Little Three Dragons and Little Four Winds) have been abandoned.
