Ultimate Tic Tac Toe
My team and I have implemented what you call Ultimate Tic Tac Toe as what we call Tic Tac Toe Ten.  We put it out for iOS, Android, Windows Phone and have made board game sets to go into school districts with starting in 2008.  If any of you in this community are interested in helping us to build out the backend analytics infrastructure to help us make the academic breakdown of this game useful for teachers and students please visit our community at <a href="https://www.facebook.com/tictactoeten" rel="nofollow">https://www.facebook.com/tictactoeten</a> and drop me a message or DM us on Twitter (@tictactoeten) ... we are also always looking for volunteers at our school tournaments where we pit kids against each other March Madness style with brackets and give out prizes to the winners ... we are here in the Bay Area, hope to meet some of you guys soon :)<p>cheers,
