Analytical Articles on Mah-Jong

This site will be devoted to game of MAH-JONG. Rules are mostly CO ("Chinese Official") though it might be of use for un-American styles also.

In particular, through extensive calculations some items were identified and quantified adding knowledge on Mah-Jong game strategy.

I share my findings and I am sure that ultimately it might help to cope with real table problems.

As some examples-teasers I ask you to answer the following questions:

·        Why two-suiter B33345 C55567 calls for 4 tiles?

·        How many waits is “Nine Gates” (1112345678999)?

·        What are most popular “Scoring Elements” to finish hand (under “CO” Rules)?

·        Having 22222111 what is do better: to Pung or to collect “Seven Pairs”?

·        For how long you should wait until needed tile comes during the game?

·        Etc.

At this very site you would find answers for above questions and much more..


P.S. Some places may be under construction.
