Some of these I've had since a child; others I've collected as an adult.
My fascination as a child started with my mom's original Rubik's Cube and white Pyraminx, and also my dad's Link the Rings. As I was growing up, my mom continued to by me Rubik's merchandise. I also owned a lot of mazes and assembly puzzles, which are not covered on this site.
In 2007, at 26 years old, I rekindled my obsession with Twisty Puzzles when I bought a new Rubik's Professor 5x5x5. I have since ordered a variety of products, including several items from Meffert's and a V-Cube 6.
Rubik's Cube (OddzOn)
Official Rubik's Cubes. I also own a number of DIYs, promos, and knockoffs.
Mine is lubed and restickered with Cubesmith tiles - Turns like a dream :-)
6X6X6 & UP
Two chessboard V-7 Cubes (black/white mods)
CUBE (SHAPE CHANGING)
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.
The 1982 Politoys version with a spindle mechanism.
The face turning dodecahedron with two layers per face. A Megaminx with an additional layer on each face.
Meffert's 2008 release with stickers instead of tiles
The white Meffert's 1981 version. I also own the 25th anniversary black w/ metallic tiles
A beautiful (but simple) puzzle closely related to the Dino Cube!
12 Color Meffert's version. Fell apart after I dropped it during solve :-(
IQ 139 Puck
I ordered two Puck Puzzles from the UK in 2007, but they never came :-(
This version has a United States flag theme.
Ball.B - Grey Dots
A mass produced spherical megaminx with a new mechanism. This version has a grey body covered with dots.
A bumped variant of the Cheese-puzzle. A one-layer six segment prism.
My mother found one on the ground in a parking lot when I was a teenager. Some of the pieces were broken/missing, and it didn't turn well.
HEADS & OBJECTS
The tile sliding puzzle from the original cube craze.
Puzzler - Novice
I owned the Avenger, with 5 different colored ovals
Rubik's Fifteen (XV)
Rubik's 15 (XV) is 2 puzzles in one. Arrange the numbers in sequence 1 to 15. On the other side there is a magic square challenge.
BETCHA CAN'T! Flexible Hexagon
Flimsy hex-magics. Mine broke within a week, so my mom got me another one, which I was extremely careful with.
The original version produced by Politoys.
A great electronic puzzle while it lasted. Mine finally wore out, sadly...
A great little puzzle that keep you busy for hours!
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.
Six coloured balls have to be moved in their matching domes.
Arrange the ten pieces by breaking them into two groups and putting them back together again.
Unscrambling The Cube III
Pretty Symmetric patterns to construct step-by-step on the cube, full-color.
A step-by-step "racing" solution
