Twist the new Perplexus Fusion to align the tracks and manipulate the ball through the inner 3D maze. The puzzle turns very easily and smoothly.
Pass each number from 1 up to 225 in turn along the track to solve the puzzle. It’s very hard not to fall off the track as you go. You even need to keep the ball balanced when you’re turning the cube to line up the tracks for the next step in the maze, so a steady hand and good dexterity is a must-have.
