How to solve the Rex cube
• Solve the edges first. Mind the color pattern to avoid mirroring/parities. algorithm to cycle edges across top -- doesn't affect back edge
• Then match the middle centers with the edges. Algorithms to cycle 3 centers: counter clockwise -- clockwise
• Then solve the side centers. Algorithm to switch side centers diagonally (FRU) in 2 faces: right hand first -- Right up up down down Twist Left up up down down -- combine with clever setup moves -- do not solve opposite faces first

Normal master Skewb:
• Solve the edges first. See Rex above.
• Place the corners.
• Solve the inner centers. See Rex above.
• Solve the outer centers. See Rex above.
• Orient the corners. Algorithm to exchange corners diagonally (FRU with Back): Up up down down, 3 times -- change back and forth, with clever setups in between, matching the colors across.
