Tracker Ball

Tracker Ball is based on an idea by Bram Cohen. It is a twisty puzzle that looks nothing like a Rubik’s Cube. It has one big spherical gear with 20 teeth (icosahedron) and three small spherical gears with 8 holes (octahedron). The big sphere gear rolls like a tracker ball supported by the three smaller sphere gears that act like ball bearings. In its solved state, the green tooth of the tracker ball is inside the green hole of one small ball, the red tooth of the tracker ball is inside the red hole of the second small ball, and the blue tooth of the tracker ball is inside the blue hole of the third small ball.

This puzzle toy looks sophisticated and interesting. It is a bit more colorful, you can see different parts and everything is fashioned with geometry. In order to play this puzzle, you must fit all the pieces in. You can scramble the pieces by turning the spherical gear at the middle. Just a warning, your fingers needs to get used to the motion of the pieces, it will quite turns smoothly once you get the hang of it. All you need to do is move it like a tracker ball.
