Nothing too crazy, but here it is.
A mass produced 2x2x2 by Verdes. Sold in traditional and pillowed shape and with back and white body.
A cube covered with sudoku-themed stickers.
6X6X6 & UP
The first mass produced 6x6x6. A six layered cube.
The first 7x7x7. A seven layered cube.
CUBE (SHAPE CHANGING)
The Bump Cube is a simple 3x3x3 Rubik's cube, but with an interesting twist. It spawned a whole series of puzzles and created a verb of its own.
Not the first fully functional 3x3x4 but the first mass produced.
Dayan Megaminx I
A new design of megaminx with ridges on the corner pieces. There is also a version without ridges under the same name.
The face turning dodecahedron with two layers per face. A Megaminx with an additional layer on each face.
A face turning dodecahedron with only 4 pieces along one edge.
This is a newer version of the Megaminx, published by Meffert, with tiles and 12 distinct colors.
At the time it was the most valuable puzzle known to exist. What else can somebody say about a puzzle sold for $3550?
Essentially a deeper cut megaminx at heart, the Pyraminx crystal adds a new twist to the classic puzzle.
A three layered Megaminx. One of the most famous custom twisty puzzles before mass production started.
The puzzle is an extension of the Megaminx to a truncated icosahedron (soccerball or buckyball for the chemists).
All 32 sides are rotatable.
A 2x2x2 with 6 rings with 12 segments each.
