x= R

y= U

z= F

For all of these moves the permutation picture is what you should have on the U face unless

otherwise noted. The second to last permutation on this page you must be able to do backwards.This is because there are 4 ways that you can have that particular case come up: normal as in thepicture, backwards (flip all arrows to point in the opposite direction) and reflections of both of

those. I also strongly recommend knowing the moves that I give you the backwards move for

you. In these cases I also recommend knowing the reflections for both the normal and backwardsmoves. Doing this will help you to complete these cases in quicker times no matter how they

come up.

Case Move/Video/Notes-Comments

1) R U F B' R F' B U Rno video

avail.I don't actually use any finger tricks for this move. With alittle practice and some dexterity this move can go fairly

quickly (2 seconds or less).

1) R U' F B' R F' B U' Rno video

It takes a while to get used to (B R F' R) but practice it slowly

and you're hands will start to get used to it.

1) (R' F R') B (R F' R') (B R) no video avail.

This one is pretty straight-forward

4/5

1) (L F' L) D (R' B R) D L B (L F L' B')no videoavail.

It can be difficult to include the last B' in the last trigger

sometimes but I always try to.

1) U' B' U B U' (R' F R) B' (R' F' R) (U' B)no video

avail.

The first U' is to correct for the last layer being out of

position after the rest of the algorithm. It may not always be

necessary to do this move.

1) B (L U L') B (R D' R D R)

Video:slow

fast

To get the full effect of the last trigger turn the cube upsidedown just before you get to it (see the video). The

last trigger can be performed extremely quickly (at times less

than 0.5 second).

1) R B U' (B' R D) B' (L' B' L) B (D' R)no video

avail.

The D' in (B' R D') is somewhat difficult to perform quickly(compared with the ease of most triggers) but I always try touse it in the trigger anyway.

1) (F U F') L D' ( (B U') (B' U B') ) (D L)no video

avail.

Treat the two middle triggers as one hand motion. It isessential that you know the reflection for this move.

1) L D' (B U' B U B') (D L) (F U' F')no videoavail.

The first trigger goes pretty quickly. It is essential that you

know the reflection for this move.


5/5

1) (R U' R2) (F2 U' R F2 R') (U F2) (R2 U R') (U')

1a) (R U' R2) (F2 U' R F2 R') (x2 y) (D R2) y (r2 U L') (U')

2) (L D') (B L') D (R F' R') (D L) (B') (L' D L')

Video#2:

slow

fast

(4-23-03)I just recently figured out the finger trick to #1 (Thanks Justin

Vining for the move). The last U' should be treated as anoptional move. #1a lists the move noting where I do cube

rotations. In order to do the 5 move trigger, turn the first F2 turn

clockwise. Also, begin to do the rotation (x2 y) during the 5

move trigger. When doing r2 in the last trigger (r2 U L') in #1atry to turn both the L face and r at the same time, where r

means to turn R as well as the middle face at the same time.

#2 is my old way of doing this move which is ridiculously slow

(at least for my hands). See the video for further clarification onthat move.
