Speedcubing: 4x4x4 BLD in 24:32.12 Minutes [Single]

Memorization: 13:00 minutes
Execution: 11:32 minutes (starts at 2:13)

Hell yeah! I did it!

My first attempt was a DNF because of 3 switched edges. This solve was my second attempt and it was already a success!

Memorization-method: Centers and edges with letter-pairs, corners with visual memo.
Execution-method: At first, I solve the centers with the U2-method. After that, I solve the corners with Old Pochmann and at the end, I solve the edges with the r2-method.

What cube do you use? It's the 4x4x4 speedcube from

What method do you use? I use commutators for centres, r2 for edges, and 3OP for corners.

What memo system do you use? I assign letters to the pieces, and then make stories out of the letters (first letter of each word in the story). Then I imagine the stories happening around various (pre-decided) rooms. So when I'm solving, I think of the room that I need, then I can easily recall the story, and then I know what pieces need to go where. Sorry if that was confusing.

Why do you sometimes look to the side? Read above description of my memo system. I look to the side because some of my sotries take place in the room I'm in, so it helps to look to the place where the story is taking place.

Why do you tap pieces sometimes? That's me decoding my stories back into pieces. Tapping the pieces helps me to make me more aware of where the piece exactly is.

Why are you wearing earmuffs? They are just ear defenders (the sort of thing ballistics testers might use) so that any outside noise is cut out.

What's the World Record? It is currently 4:42.34 by Ville Seppänen from Finland

What is your World Ranking? My official 4x4x4bld time is 18:51 which puts me 35th. The solve on video would put me 6th if I did it in an official competition
