I have many other puzzles, but here are my twisty puzzles:
6X6X6 & UP
The first mass produced 6x6x6. A six layered cube.
The first 7x7x7. A seven layered cube.
CUBE (SHAPE CHANGING)
The 1994 Irwin Toys version.
Meffert's six colour 1982 version. Roughly 31 mm along an edge.
The black 1981 Meffert version.
HEADS & OBJECTS
Because of the restricting (yellow) axis, this is an edges and corners only puzzle and NOT another 3x3x3 sliding block puzzle
Probably the most popular tile sliding puzzle ever.
This 3x6 Whip-It stands approximately 7cm tall. Produced in Macau. Original LJN Whip-Its were made in Hong Kong.
