Ultimate Tic-Tac-Toe....

I know, I know.  I don't post for weeks and then you read this title.  Hear me out - work is crazy, dog is quite sick, and basically the only time I've had off was last weekend.  Speaking of which, we went to Origins for another fun weekend and I'll post some convention pics by the weekend.

But seriously, check out this link.  I scoffed at first but then I read ALL the rules.  It is actually a pretty clever and rather tricky variant.  Which is probably why it showed up on a math blog.  And yes, it's probably eventually solvable but then isn't every abstract?

(Thanks for the tip, Gilad...)
