Boooogus! I created two accounts (easy to do with a couple spare email aliases). For one I took 2-3 hours to complete (really thinking about the answers). For the other I consistently filled in all the multiple-guess boxes in a diagonal pattern, i.e. start at the upper right of a block and proceed down to the opposite corner across the block. When you get to the far side, reverse direction on the opposite diagonal, etc. I GOT THE SAME MATCHES ! "29 dimensions" my -ss!
