I was looking for an iPhone version of this 4x4x4 tic tac toe game but couldn't find it because of it's odd name. I used to play the 3D board game version called Qubix and I wrote my own version when computers still used punch cards. This version plays a hard game at level 10 which I can sometimes beat if I go first. I tied once and it didn't report that the game was over even though there were no moves left. Still it is free, fast, and challenging.The board layout alignment is off so it is hard to see diagonals, but that's part of the callenge.It would be nice if it kept win/loss statistics but maybe you don't want to remember how often it beats you.

Basic grid, but don't let that fool you. This is a very challenging game, really makes you think. And no ads!

All I have to say is that it's free and better than the two dimensional 3 by 3 version.

I looked into a bunch of 4x4x4 apps because it's hard to find other people to play. All of them weren't true 4x4x4 games. This one really delivered, and is well worth the couple bucks. Maybe the computer is a little too hard on lvl 2, or maybe I'm just a dunce :-) I definitely recommend this app!
