try gaining the corners. I'm winning on about a 50% clip

I was put accidently in a bonehead math class when I was 14 through some clerical error and the teach was gone half the time.
I invented a form of 3D tic tac toe and did 3^2, 4^2, and 5^2 versions
just drawing the layers side by side on a blackboard so it was a bit harder to visualize.
We passed quite a bit of time in bonehead that way.

Multi-level game
Gets addictive.

So, if anyone else was wondering - the reason this is a 4x3x3 game is because the 3x3x3 game is defunct...

On 3x3x3 there is always a 3x3 grid in wich the second player didn't take the centre on his first move.
I played the 4x4x4 game with the same thing in mind, i started in the centre, creating a 2x2 square in on of the two middle planes. I defended only when the opponent had three in a row and managed to play a winning move.
