Here is the same lesson the app teaches, played all the way through. Watch the whole solve first, then come back to whichever stage you are stuck on.
One mixed-up cube, seven stages, and every piece back home by the end.
Seven short clips, one per stage. Each one starts where the last one finished.
A white plus sign on the bottom, with each edge matching its side colour.
Fill the four corners so the whole bottom layer is white.
Slide the side edges into their slots, like drawers.
Flip yellow stickers up until there is a plus on top.
Spin the top edges until each one matches its side colour.
Move the last corners into their right seats. Twisted is fine for now.
Twist each corner until yellow faces up. Nearly there!
