This uniquely shaped puzzle seems to exactly match the shape of a UFO! Even as you attempt to take out the spherical piece in the center, it spins freely, which makes grasping the solution a galactic challenge. Level 4 puzzles are considered challenging by most puzzlers. Created by Finnish puzzle designer Vesa Timonen.
