# Solving the Rubik's Cube in Sub 13 Algs, BLD!

Submitted by Dbeyer on Sat, 07/29/2006 - 06:08.

Ok, this method is called Simul Block, or Shotgun. It's a very powerful bld method, using 8 new algs, and putting some old algs to new uses, or using uncommon variations of a common algorithm.

This is an advanced version of Pochmann, the method has three key steps.

Solve the F/B face + 1 S Edge (the UL as Default)

Roux Cycle the last three edges

Parity Fix.

The parity is something common in bld, so most of you will laugh at this. My method never encounters the 2 Corner 2 Edge swap parity, because that's what my system is based on.

It's something that 4 Step Solvers encounter, and they deal w/ it first.

Here is an example solve, ten algs to solve the cube.

Scramble:

U' D2 L' F' D R' B2 F L' R2 F2 L' B U2 D2 R B' L U2 F L U B2 L2 B

Solve:

E [F'RFU'F'RURU'R2FU] E'

M F2 [y'(r2)U2R'FRU2(r2)FLF'L'y] F2 M'

M2 L' [l2)U2LF'L'U2(l2)F'R'FR] L M2

E2 L [F'RFU'F'RURU'R2FU] L' E2

M' D' [y'(r2)U2R'FRU2(r2)FLF'L'y] D M

DMD'L2 [L'U'LF2R'DR'D'R2F2] L2 DM'D'

E' D2 [U2(r2)U'FU(r2)U2FUF'U'] D2 E

F [L'U'LF2R'DR'D'R2F2] F'

S2, y, x

RB [M'UM'UMU2MUMUMU2] B'R'

U2 M' U2 M

The solve before this it took 9 algs.

I'm releasing the details to individuals first, but letting the public know that it's possible to solve the cube very fast, and not having to learn COEOCPEP.
