Here is my current collection it's relatively small compared to Georges xD
Rubik's Revenge (ITC)
Follow up to the Rubik's cube, as shown by its name.
Produced in 1982 and 1983 by Ideal Toy Corporation in Korea, Macau and Hong Kong.
6X6X6 & UP
The first mass produced 6x6x6. A six layered cube.
The first 7x7x7. A seven layered cube.
CUBE (SHAPE PRESERVING)
Years before the Floppy Cube bandaging a 3x3x3 was the best way to create this easy puzzle, perfect for newcomers.
The deepcut corner turning cube.
CUBE (SHAPE CHANGING)
Fisher's Golden Cube
All the stickers on this 78 mm modified Skewb are the same reflective golden colour. There is only one solution.
Get back to Square-1
An american based version of the Square-1. It distinguishes itself from the other variants because it was sold in scrambled state.
Meffert's build-up and truncation of a Skewb into an octahedron.
A jumbling only puzzle which fills a missing slot in the series of face turning tetragonal trapezohedrons between the Crystal Trap and the jumble Trap.
This is a newer version of the Megaminx, published by Meffert, with tiles and 12 distinct colors.
A higher-order Pyramorphix. A 3x3x3 transformed into the shape of a tetrahedron.
A bumped variant of the Cheese-puzzle. A one-layer six segment prism.
An attractive little puzzle, possibly related to the legendary Rubik's Cheeze.
The tile sliding puzzle from the original cube craze.
Net Block UFO
Rotate the top/bottom half, then spin each half of a sphere to scramble the puzzle.
