|Rubik's Cube: Fewest moves (half turn metrics)|
|1||19||Tony Snyder||My focus for several years has been to discover a way to do a true direct solve. Years ago I could get one direct solve out of about 10 from a cube mixed with 13 turns (the number of turns to mix a cube in the original contests), however, not until today did I finally direct solve a fully mixed cube (with more than 25 turns to the mix). Up to this point I had several 24's and a 23, close but not close enough. Believe it or not with today's 19 turn solve I only studied for a few seconds. The key is to use what you learned from the algorithms, not the algorithms themselves, then combine and adapt as you go.||20070806|

I have twice achieved 19 turns in the fewest moves challenge FMC. The first time it was achieved with an advanced edges first solution leaving a 3-corner insertion. The second time i did it with a much easier scramble. Only 7 or 8 turns to turn the rest of the solution into a Domino solve (the subgroup. This solution was only 1 turn off the optimal solution for that scramble. Fewest moves id fun but very time consuming. The best way to go is probably block building and corners insertion or edges first. Both rely heavily on good insertiontechnique for the final (3 4 or 5) corners!!

My solve: L U' F2 D' U2 B R2 F' U F2 U'B U F' R U2 R' U2 R2
found in 20 minutes or so.
explanation: 2x2x2: L U F2 D'
pseudo F2L minus pair: U2 B R2 B.
last pair + LL edges: F' U F R U2 R'U2 R2
leaving a corner 3 cycle.
at dot insert B' U F2 U'B U F2 U', 5 moves cancel
NB. Mirek Goljan found that same solution and claimed to find it in 16min 15sec.
|1||19||Mirek Goljan||My personal record happened on the same scramble as Guus's in August 2008. See Per's site FMC 203 1-hour limit at http://fmc.mustcube.net/results.php?|
The scramble was D U' F2 U' R' F R2 B D' B R F B' U R' D2 L' R2 F2 B' U' B D B2 F2 U L F U' B2
Solution L U' F2 U2 D' B R2 F' U F2 U' B U F' R U2 R' U2 R2 obtained by block building and insertion techniques.
2X2X3: L U' F2 U2 D' B2
B' R2 B F' U F * R U2 R' U2 R2
insert 3-cycle at * F' U' B' U F2 U' B U F'
I had it in 10 minutes with one missing '. Full corrected solution written down was in 16 minutes 15 sec.

|7||22||Arnaud van Galen||Done within 1 hour for Weekly competition 2008-21. I might never beat this again because this solve only really had 1 weak spot (the 4th pair) and even that didn't take many moves if you consider how it affected the last layer.||20080525|
|9||23||Michael Swan||Saw somebody elses solve and realized that they counted M moves as one. I just did the same. Once I had it solved in 18 moves (no M moves) EXCEPT two corners were flipped counter-clockwise. I'm too impatient to get these solves very often but It's not uncommon for me to get sub 30 turns.||20080111|

This left two unoriented corners which I used 2 3-cycles to fix. I first found the insertion B' D2 B U' B' D2 B (8) inserted at the . which cancels 5 moves! Then insert U R' U' L' U R U' L (8) at the * canceling 5 moves!
WOW! Perfect insertions! 6 moves to orient two corners! I'm so happy!

|18||27||Jack Moseley||I started with an 11 move 2x2x3, then found another 9 moves for a pseudo F2L. Then I turned the top face so that the last move of the OLL would cancel out with undoing the pseudo block, had a 6 move OLL and PLL skip.||20071016|

Found B'.D' B2 F R2 U F' U R' F R2 B R F D F' D' L' D' L which left 1 corner 3-cycle. Then I inserted B2 L' F2 L B2 L' F2 L at the dot and canceled one move.

It was an insertion of 13 moves (setup+Uperm) that cancelled 5moves so that insertion became only 8 moves. I also found another insertion that would have made it 28HTM and 25STM. I'm getting consistent low 30's when I try a scramble for hours and mid-high 30's under an hour.

I tried making a 1x2x2 with the pairs already made but failed. So I made a new pair and combined it into a 1x2x2 and then combine the pairs together to make a triple-X cross. Added pre-moves for obvious reasons. The skeleton finish was long compared to the block-building in the beginning so I tried the one move insertions (technique from I don't remember who). L & L' wasn't good either but L2 already had two pairs made in a good position after the triple-X cross. So I went with the 21-move skeleton.

|49||43||Dylan Moore||Not incredibly lucky. I switch off between the cross, or Lars's method. For this one I used the "extended cross" as described by Chris Hardwick. Thanks Chris! The only thing that might have been constiered lucky was it only took me 5 moves for the extended cross.|
|49||43||Ryan Prophet||Straightforward F2L/OLL/PLL solve, easy F2L but not lucky. Currently working on looking ahead and combining F2L moves to place multiple corners simultaneously. Using this method I should be able to get down as low as 35 moves still using OLL/PLL.||20080701|
