Does anyone else get this problem, you use a RUBIKS 4x4x4 and it just pops at least 10 times during a speedsolve, the thing is, i don't like, go mega fast wit hit, is there anything i can do to stop it popping? :] thanks. Tom.
I have a rubik's 4x4x4 too, and it also pops sometimes. Although I sometimes don't know why, I think a few times it was because the part of the center piece that goes inside the grooves on the sphere was broken, so the edge next to it could easily be taken out. See if any of the edges can be pulled out really easily on your cube.
