Moyu has just recently released this high quality skewb modification that adds an extra layer of difficulty to the normal skewb. Depending on which corners you turn, the inner centerpieces will move or remain stationary, thus scrambling the inner layer. Not every turn will scramble the centers so try and keep track of what pieces move with each turn! This Double Skewb is similar but not the same as Carl Hof’s Dual Skewb puzzle. Hopefully one day we’ll see Carl’s Dual Skewb mass-produced as well!
