It is similar to Layer by layer but uses much fewer algorithms.

Solve 3 corners Use the Cross:3C step to have the 1st Layer-1C cube state : * (Beginner) Holding the cross on D, place D-layer corners above their position in the U-layer and repeat the sexy move (R U R' U' ) until placed. * (Advanced) Intuitive Solve 3 E-slice edges Use the +3E edg keyhole step to have the F2L-1 cube state (see Keyhole method) (Or by application of the alg R' U' R' U' R' U R U R and/or its mirror L U L U L U' L' U' L' ) Solve remaining edges Use the F2L-1:+5E step to have the 5 Corners Missing cube state: * (Beginner) This can be done in 2 substeps (8355 keyhole method) : + Solve 3 U-layer edges: (intuitive) Hold the remaining unsolved corner+edge positions in the front-right. Using R or F', place a U-layer edge into the correct position. Now twist the U layer to replace it with an unsolved U-layer edge and undo the original R' or F move. Repeat until 3 U-layer edges are solved. + Solve the final 2 edges: Swap the FR E-slice edge with the edge in UF without disturbing the other edges using the alg R U R' U R U R' or its mirror F' U' F U' F' U' F, depending on the orientation of the edge in the slot. Solve the final 5 corners Use the 5CM:Sexy*+S step to have the Solved cube state: Flip the cube over so that 4 of the remaining corners are in the D-layer and the other remaining corner is in the FR position of the U-layer. The corner in the U layer will be used as a 'buffer'. 1. If the corner in the buffer does not belong in the D-layer apply the alg R U R' U' (the sexy move) once to place a D-layer corner into the buffer. 2. Twist the D-layer until the corner in the buffer position is directly above its correct position in the D-layer. 3. Repeat the alg R U R' U' until the corner in the buffer position is placed correctly in the D-layer. 4. Repeat steps 1 to 3 until only 1 unsolved corner remains in the D-layer. 5. Position the final unsolved D-layer corner under the buffer piece. 6. Repeat the alg R U R' U' until either the whole cube is solved or only 2 unsolved corners remain. If the final D corner is solved resulting in a fully solved D layer but the rest of the cube is unsolved, continue applying the algorithm until you are left with two unsolved corners, then continue with the instructions below. 7. Rotate the whole cube so that the D-layer now contains the 2 unsolved corners, re-assigning a solved corner in the U-layer as the new buffer piece. 8. Repeat steps 2 and 3 until the cube is solved. Advancements There are a number of advancements which can be made to lower the move-count and improve speed of execution. Here are a few of them: * Solving the Cross: Minimise move count and plan the entire cross during inspection * First 3 Corners: Use the inverse of the sexy move to reduce the number of repetitions required. For maximal efficiency, depending on the corner orientation use one of: + R U R' + F' U' F + R B U2 B' R' * Solve 3 E-slice edges: Combine first 3 corners and edges into one step by joining corner + edge pairs in the U-layer and inserting as a pair, see F2L * Solve U-Layer edges: Try also building corner/edge pairs while solving the edges to reduce the number of corners left at the end, see Heise Method. * Last 5 corners: Use the inverse of the sexy move (U R U' R') for corners requiring 5-repetitions of the sexy move. More advanced: Use more efficient commutators to solve several corners simultaneously. See last step of Heise Method.
