R3-T method [[File:]] Information about the method Proposer(s): Terence Tan Proposed: 2018 Alt Names: Reduction3-T Variants: none No. Steps: 6+ No. Algs: 28+ Avg Moves: ~57 Purpose(s): speedsolving one-handed solving

R3-T(bad name,I know) is a weird Petrus variant. It solve the E-slice in a similar way to Quadrangular Francisco, (a method created by Alex Yang) which is a variant of Hexagonal Francisco, ( a method by Andrew Nathenson) which is a variant of Triangular Francisco.

The E-Slice is solved efficiently and F2L is finished off in an unusual way.

Scrambled cube -> 1x2x3 block - E-Slice - EO+CO - F2L(remainder) - PLL -> Solved cube R3-T is a hybrid method that does corner orientation before finishing F2L.

Steps

1)1x2x3 block - Solve a 1x2x3 block antwhere on the cube, it will be treated as if it's in the D layer.

• For beginners, you can treat it as 3 cross pieces and 2 corners.

2)E-slice - solve the E-slice with the empty face.This can be done very efficiently.

• you can position the 1x2x3 on the left(like Roux's FB)in this step if you

want.

3)EO+CO - you solve edge-orientation and corner-orientation.(not necessarily in that order)

• Because the E-slice is already solved, there can only be 0, 2 or 4 misoriented edges.

4 misoriented edges can be solved as an EO arrow (like in LSE) e.g. (D') M'U M

2 misoriented edges can be solved using an OLL alg.(you can influence corner orientation in this step.)

• CO can be solved using 1-2 OCLL algs - 7 algs.

(orient the corners stuck in the D layer by doing an R2 first)

• This can also be done by solving only 3 E-edges and insert the last one with TSLE.
