Fastest time solving a completely random cube (disregarding lucky times) : 9.27 seconds 6/8/09
See my post on the forum about this solve.
Speed solving video of me solving the cube in 17.88 seconds

Fastest time solving the cube without pre-inspection (disregarding lucky times) : 14.61 seconds 9/8/07

Fastest time solving the cube with one hand (disregarding lucky times) : 25.95 seconds 7/10/2004
Speed solving video of me solving the cube one handed in 29.09 seconds

Fastest time solving a Rubik's cube (3x3x3) while blindfolded : 1 minute 7.07 seconds 1/23/08
This time represents from when I first started memorizing the cube until the cube was solved. I wore a blindfold over my eyes during the entire solving process.
Approximate memorization time: 27 seconds
Approximate solving time: 40 seconds


Fastest time solving a Rubik's Revenge cube (4x4x4) while blindfolded : 4 minutes 46.19 seconds 3/21/09
This time represents from when I first started memorizing the cube until the cube was solved. I wore a blindfold over my eyes during the entire solving process.

Fastest time solving a Rubik's Professor cube (5x5x5) while blindfolded : 12 minutes 44.14 seconds 2/10/08
This time represents from when I first started memorizing the cube until the cube was solved. I wore a blindfold over my eyes during the entire solving process.
Approximate memorization time: 6:00 minutes
Approximate solving time: 6:44 minutes


Fastest time solving the 6x6x6 cube while blindfolded : 1 hour 48 minutes 52.93 seconds 10/9/07
This time represents from when I first started memorizing the cube until the cube was solved. I wore a blindfold over my eyes during the entire solving process. I did this after the 2007 Rubik's Cube World Championships using Frank Morris' 6x6x6 cube from Olympicubes.
Approximate memorization time: 1 hour 3 minutes
Approximate solving time: 45 minutes


Fastest time solving Rubik's Revenge (4x4x4) (disregarding lucky times) : 50.70 seconds 9/8/2005

Personal best Rubik's Revenge (4x4x4) official rules average for 10 consecutive trials (middle 10 out of 12) : 1 minute 3.44 seconds 4/14/2006
57.66 1:12.05 (56.04) 1:05.97 (1:21.21) 58.90 58.71 1:08.69 1:15.59 59.59 57.68 59.58 = 1:03.44

Fastest time solving Rubik's Professor Cube (5x5x5) (disregarding lucky times) : 1 minute 57.01 seconds 5/19/2005

Fewest looks I need to solve the Rubik's cube using my normal speed solving method : 1 look

I have attempted this twice, and was successful both times. Below you'll see a record of both of my attempts. This differs from blindfold cubing in that for this record I used my normal speed solve solution, whereas in blindfold cubing I only use edge/corner movers and edge/corner flip moves. See the blindfolded records for a further explanation.

First attempt 12/16/02

Took 3 hours 14 minutes 50 seconds total.
Here's cube explorer's move to get to the scramble I had: U F2 U L2 D F2 B' L2 U' B' L2 R' F L2 B R D U2 R2
Here was my solution:
*first and only look*
(cross) D2 F' R' L' D F B
(BR pair accidently placed incorrectly) R U R2 U2 R
(FL pair) F U' F' L' U2 L
(BL pair) R U2 R' L U' L'
(place FR corner and BR edge into FR) U' R U2 R2 F R F'
(fix BR and FR) R2 U2 R2 U2 R2
(orientation case) L F R U2 R' U2 R U2 R' F' L'
(permutation case) (U) L2 B2 L' F' L B2 L' F L'
= 57 moves


Second attempt 5/6/04

Took 1 hour 54 minutes 24 seconds total. I did this for the 5/2/04 Sunday blindfold contest.
Here was the scramble: B' F' D' F' B L' U2 F L2 B' R L F2 U' D' B' U B L2 D2 L' U2 B' R2 F
Here was my solution:
*first and only look*
(Double extended cross) L' R D2 L' F' U D' L B'
(FL pair) U B' U' B F U F'
(BL pair) U' L U L' U B' U' B
(OLL) U2 R' U2 R2 B' R' B R' U2 R
(PLL) B2 R' U' R B2 L' D L' D' L2
= 44 moves
