Since 2014 when I first learned to solve 3x3, I've accumulated close to 100 puzzles. Here is my collection!
CUBE (SHAPE CHANGING)
A 3x3x3 variation built by Katsuhiko Okamoto.
A bigger version of the Gear Cube with a very fitting package.
A corner only Tuttminx.
Two years after the void version the inventor presented the first solid puzzle implementing all three dodecahedral axis systems.
The puzzle is an extension of the Megaminx to a truncated icosahedron (soccerball or buckyball for the chemists).
All 32 sides are rotatable.
Void Truncated Icosidodecahedron
A puzzle combining all three dodecahedral axis systems. It was built before all smaller variants were completed, void or not.
A Tuttminx with 32 central gears made visible with the help of 32 flower like shapes.
A Dino dodecahedron in shape of a sphere.
A mass produced spherical Gear Cube.
Giga Rhombic Tuttminx
A higher order version of the Fake Tuttminx. 42 axis with two layers each and 32 colours.
A Tuttminx in spherical shape with the pentagons replaced by heptagons.
A sphercial version of the Fake Tuttminx. 42 axis and 80 colours.
ROUND CONVEX SHAPES
A mass produced variant of a 3x3x3 in shape of a diamond.
HEADS & OBJECTS
A 3x3x3 in shape of an apple. A red and a green version exists.
14 pieces rotating on a sphere divided in 3 (!) distinct layers.
Three intersecting circles which do NOT make up a planar surface.
