#5X5 RUBIX CUBE FLIP MIDDLE TRIAL#

Then execute this algorithm to exchange the bottom cubie of the left triple edge with the top cubie of the right triple edge. Orient the cube so that the two inside out triple edges are on the left and right edge of the front face. If Step 3 finishes with two triple edges oriented incorrectly (middle cubie is opposite orientation from two neighbor cubies), no new algorithms are needed, you can use the Edge Swapping algorithm (which swaps a cubie between the left and right triple edges) to fix them.

All other triple edges should be properly oriented. This should be performed with the inside out triple edge at the top front (the cube's 'forehead').

If Step 3 finishes with one triple edge oriented incorrectly (middle cubie is opposite orientation from two neighbor cubies), a new algorithm is needed to flip the middle cubie of one triple edge only. The third way is if two triple edges are oriented inside out.Ĭongratulations! You're already done with Step 4. The second way is if one triple edge is oriented inside out, which requires a new algorithm exclusive to the 5x5 cube. The first and easiest way is if there are no triple edges that are oriented 'inside out' (the middle cubie is of the opposite orientation from its two neighbor cubies). Step 4: Correct the Triple Edge Orientation This step should conclude with either zero, one, or two triple edges that have their center cubie oriented inside out from the other two cubies. Solve the last remaining two triple edges using the algorithm from the 4x4 Rubiks Revenge that brings together two edge pieces that are on opposite sides/ends of a face (see the Rubiks Revenge#Algorithms section for this edge-swapping algorithm).With the cube oriented such that the top and bottom faces have all their triple edges solved, rotate the back face once and solve the two triple edges in the front.Flip the cube upside down and repeat the above procedure, so that eight total triple edges (four on the top and four on the bottom) are solved.Repeat the above procedure until all 4 triple-edges of the top face are solved (meaning, the three cubies of the triple edge have matching colors and orientations).Line up the three cubies in a triple edge and 'store' it on the top of the cube.Use algorithms to line up triple edges so that they are all of a single color combination. Without this algorithm, you'd have to perform the above algorithm for adjacent faces at least twice to move the corner cubie from face to face. White swaps with yellow, blue swaps with green, red swaps with orange. This algorithm will swap the top right cubie on a given face with its corresponding cubie on the opposite face of the cube. The following diagram shows an asterisk on the two cubies that will be swapped: This algorithm will swap the corner cubie on the top left of the front face with the corner cubie on the bottom left of the top face. The algorithm to swap corner cubies on faces: Use the algorithm below to exchange the cubies on the corners of the center of the face (the non-cross face cubies) until each face of the cube has a solid 3x3 face of a single color. (Note that because of the odd parity of the cube, and in contrast to the 4x4, the center pieces are fixed in place, so no extra checking is required to ensure the faces are correctly oriented.) The goal of the second step is to make all nine cubies on the center faces the correct color.

Like the 3x3 step of forming a cross, this step utilizes a few algorithms that are simple enough to work out through trial and error - nothing very tricky. Start with yellow cross, then do white cross on opposite face. Solution Algorithm Steps Step 1: Center Crossesįorm the crosses on each respective cube face. 1.4 Step 4: Correct the Triple Edge Orientation.
