Would you believe this is actually just a 2×2? David Pitcher created this mind-bending shape modification in 2016 and he called it the Biocopter 6. It turns on six axis and shape-shifts like crazy, but does not jumble. Pitcher reached an agreement with Dian Sheng in 2020 to have the puzzle mass-produced and they are calling it the FlyMouse. We think Biocopter 6 is a much cooler name than FlyMouse, but we’ll admit the puzzle does look like a computer mouse! The puzzle turns great and provides a bigger challenge than the standard 2×2 puzzle. Scramble it up and give it a try!
