I was thinking about the adjacent 3's rule today during a meeting (I'm not sure what that says about me... let's just say the meeting was _REALLY_ boring).  Anyways, there's an exception to that rule.  Consider a playing field of 3 squares wide, 2 squares high, and the middle column contains 3 over 3.  The only solution is a box around the 3's. 

Just thought it was interesting.    Wonder if any of the other rules have small-puzzle exceptions like that.

Oh, and also, the number 4 should be available to put in a square for that really difficult 1x1 puzzle...
