Marcus has got the wood on me. I have not beaten him at mah jongg for some time. He is crafty but he is also damnably lucky. The flowers and seasons are 8 tiles that you can keep and put aside when you pick one up - they are an aspect of mah jongg that is pure luck. On average I pick up 2 and Marcus gets the other six.
Mostly for my protection we have set a scoring limit of 2000 per hand. It's just as well because on our last hand Marcus scored 11,520 to my 268. Ouch.
