This looked like a nightmare! Super cool to see the complexity and innovation of puzzles like these. I just ordered my first triaphum product (the legendary 3x5x7) from him and it should arrive soon. Always enjoy your videos and seeing what crazy new puzzles are out there!
Hmm, good question. There are those that are hard because they take concentration due to long algorithms, like the Eitan's star and its radio cube modifications. There are those that take a while to figure out strategies and skew your perspective, the crazy circle puzzles and the ghost skewb. Ultimately, once figured out, like any problem, all puzzles become simple. I have a few puzzles that I have still yet to scramble that just may take that position!
