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 skewb is a very solid and satisfying puzzle to play with.
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.
Meffert's build-up and truncation of a Skewb into an octahedron.
This is a newer version of the Megaminx, published by Meffert, with tiles and 12 distinct colors.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.
An attractive little puzzle, possibly related to the legendary Rubik's Cheeze.
The tile sliding puzzle from the original cube craze.
This 4x6, 60 mm Whip-It is designed to look like a pop can.
Net Block UFO
Rotate the top/bottom half, then spin each half of a sphere to scramble the puzzle.
