Although 90% of my collection is made up of metalic disentanglement puzzles that aren't included here, these are a few of my favorites that I have gotten a hold of. I try to have all different types and not just the same of one thing.
The original Rubik's cube with different shades of black, grey and white.
Pyraminx (different seal)
The white Meffert's 1981 version. This package seems to have a different sticker/seal design.
Space Shuttle was an Octagonal Prism sold with one side rotated 90 degrees. Sold in a cylinder case like some cubes once were.
A black globe on a stand with the seven continents in various colours.
A confusing 12 sided puzzle, closely related to the Megaminx.
An attractive little puzzle, possibly related to the legendary Rubik's Cheeze.
Back Spin / Loophole
A mix between the moving hole puzzles and the two-layer UFO puzzles.
Probably the most popular tile sliding puzzle ever.
This 6x6, hex-shaped Whip-It stands 85 mm tall and 40 mm wide (edge to edge).
A moving-ball puzzle with three-levels of difficulty.
Ten overlapping wheels.
Was sold with black and white body
SIAMESE & FUSED
The original version produced by Politoys.
An electronic-based multi-game-object which looks like the puzzle that started it all.
Twist and slide the top face of the cube to move the lights until you reach the solution.
Starting with all six balls inside the center sphere and the locking rings open, the challenge is to move the balls into their matching coloured domes on the outside.
Try and remove the inner sliding mechanism, blocked by knobs you can only turn one at a time.
The object of this puzzle is to get all the sliders either in or out. Several stacked and slotted disks inside the puzzle limit the range of movement at each step in the puzzle.
It's a race to make the scrambled "Cube Face"
A reusable plastic version of the now well-known Sudoku game.
