[Icehouse] 2 player Zendo

[Christopher Hickman]

I have a two-player Zendo variant, but since my group has never  
really cared about who wins, it has no points, etc.  It's just a way  
to play Zendo when you only have one other player.  I call it  
Symbiotic Zendo.

Each of the two players are simultaneously master and student.  Each  
player comes up with a rule and builds one koan that has the Buddha  
nature and one that does not. The first player marks his koans with  
white and black stones and the second player marks her koans with  
green and red stones (white stoned koans have the Buddha nature for  
the first player's rule and green stones have the Buddha nature for  
the second player's rule).  As such, each koan on the table is marked  
with two stones, meaning it can be white-green, white-red, black- 
green, or black-red.  Play begins with a randomly chosen player, and  
each player takes turns building a koan and calling master or mondo  
as per normal. With the exception of the starting koans, you do not  
mark the koans you build until after the student builds a koan for  
the round, but before the master/mondo call. Play continues after a  
player correctly guesses until his own rule is also guessed, or the  
players agree to conclude.

If you wanted to inject points into it, I'd say to award 1 point for  
each correct guess, and a bonus point if you guessed correctly on the  
turn immediately following the other player's correct guess, or  
perhaps you could use Kory's range idea in conjunction with this.
