We can all use a break from mathematics once in awhile. **Circle Tic Tac Toe fun** is a game of Tic Tac Toe that differs from the classic. Circle Tic Tac Toe fun is done with four concentric and pie slices, as opposed to the usual three by three grid. One can get four in a row straight out on the pie slice, around one of the circle slices, or diagonally out along the concentric circles.

Alright so we're going to take a little bit of break from Math stuff and introduce you to a game that I actually don't know if I came up with it but I played a lot of it when I was in Algebra 2. And what is called it's called circle tic tac toe, so what I have behind me is 4 concentric circles and actually the only time in the world I can actually draw circles is when I'm actually drawing this game. So 4 concentric circles and then we have divided up into quarters and then quarters again. So we actually have 8 segments, 4 concentric circles. And the objective of the game is to basically get 4 in a row similar to tic tac toe, and how you do that is you either get a pie slice sort of 4 row in a pie you can't go through the center. 4 in a row in a concentric circle sort of in the same circle area so we can do 1, 2, 3, 4 or the how you want to see is 4 in a row in a diagonal. So you can connect by a corner sort of go here connect by a corner go here, connect by a corner to here, connect by the same corner to this and to that.

Diagonal is the hardest one to see okay so basically those are the 3 ways you play and I like it because it's a little bit more challenging than normal tic tac toe where if you learn the game you just [sta] every time you're playing this and all the years I've played it I've only had a couple of ties. So what we're going to do is bring out our lovely assistant Allison who is frequently behind the scenes if you can get great shot at her pants they're really quite amazing okay nice Pj's at work. And we're just going to do a brief demo okay I warn you that I have actually one if the most unbeatable strategies for this game but because of Allison I'm going to turn it down a notch. So let's start it off let's do it, interesting strategy this game is going to be a little bit longer than I anticipated where should I go?

Right now if you do the right move, there you go and so if you noticed she actually has 3 in a row and either side is in a box so she can win right now I can't block this side and this side, so unless I can win right now I actually have lost a game and my only 3 in a row chance was this one right here which I gave up to go over here for some unknown reason. So I'm just going to go here to make myself feel good that if I had another move I would win but she goes ahead and wins a game. So there you go circle tic tac toe it's a little bit more of a brainiac version of normal tic tac toe little bit more strategy involved but I would say even more fun enjoy.
