3 Level Chess?

I'm been wondering if this type of chess does exist. I don't know. I don't even know how would you play a three level chess. It would be to difficult. At first, how would you move the pieces up & down? You would have to change their range of movement to move them up & down the levels or reach a certain point in the chess board. Again, it would be to difficult. Another thing is that you would have to concentrate on the three levels. You wouldn't be able to do that right?  Well, at least I couldn't concentrate on three boards. Another matter is that you would have to create new rules and distort the old ones,  but i digress... you be the judges & contact me if you have any info on this matter. I want to know if this type of chess exists and if you can even play it. Thanx in Advance.
