		<description>I think there&#039;s something you don&#039;t understand. If you first cut off X (assuming in your picture that X grows from the root), then X disappears, of course. After that, if you cut of Y, X will not magically reappear. Which bit of the text is unclear to you?</description>

		<description>Hi,

Cool game.  But I think it has a bug.  You don&#039;t seem to eliminate a head attached to the root when picked, so that those &quot;root heads&quot; get replicated when you subsequently pick a non root head to eliminate.

If I have this to start:

O  Y  X 
\ /  /  
 O  /  
 &#124; / 
 O

And eliminate the X, and then the Y, it&#039;s as if I never eliminated the X at all.

Or perhaps I don&#039;t understand the game...
