What is the most annoying "3x3" cube to solve?
Alright so i've gotten into solving these puzzles for about a year now and its like a fun fidget toy in my eyes. I can solve them consistently. But the "Mirror cube" has the the most annoying for me to solve. I always viewed these has the basic 3x3 with a twist and they are fun the the constant feelings and feeling of turning the cube is hindered by the mirror. Any cube that are simple yet annoying to solve you guys know of?
