I like this effect in general, but I am not in love with it. I have written in reviews of other
effects that I will often try to guess how the effect is achieved, and then I am surprised by the
actual method used. That is not the case here. I immediately had a thought of how this effect was
pulled off, and upon watching the instruction, it was exactly as I thought. Without giving anything
away - I think the principles behind the effect are sound, and can definitely be applied in ways
that (in my opinion) would be better, but the choice of tic tac toe for the routine itself cheapens
an otherwise good idea. To put this in perspective, I performed this effect exactly as taught for my
non-magician, elementary school teacher wife and she immediately correctly guessed how it was done
even if she couldn't replicate all the beats herself. All complaints aside, I still rate this a 4,
because you can take the principles and theory behind the trick and apply that to other effects.
