Curious Cross . . . multi-colored

I originally acquired 3 units in one sale, each a solid color throughout :   amber, red and blue .   Instead of taking a pic with all three, I decided to mix the pieces and come out with the multicolored version .   I bought my first one (clear) 30+ years ago from Mag-Nif Inc .   Reiss Games' version is called Torment from 1974 .

Rubik's Shells . . . a.k.a.   Intelligence Magic Wheel

Purchased from Johore, Malaysia.
Their store can be accessed at their eBay store  tropicalestore
Or you can email them at  tropicalestore@yahoo.com

Rubik Shells is a puzzle that consists of 4 intersecting rings, coloured wheels with 8 balls each, which can rotate. The wheels are in two pairs; two axes with a pair of wheels on each, and the two axes are separated and at right angles to each other so that any wheels from one axis has exactly one ball in common with any wheel from the other axis.

The object of the puzzle is to separate the coloured balls, each colour into its own wheel.

There are 28 balls, 7 of each colour. There are 4 intersections, so 4 balls will belong to two wheels simultaneously. Each wheel intersects two others, so in the solved state each wheel will have one intersection of its own colour, and the ball at the other intersection matches that of the other wheel.

An interesting feature of this puzzle is that each axis also has a button. By pressing a button, the two wheels on that axis permanently lock together.

There are therefore 3 grades of difficulty:

Basic (no buttons pressed)
Tough (one button pressed)
Challenge (both buttons pressed).

Note that once pressed, the buttons can never be released. Also, the puzzle is always solvable, even if the buttons are pressed when it is in a mixed state. Pressing a button takes some force, so there is no danger of doing so accidentally.

Mini triangle burr   . . . origin unknown .

Mini burr   Unknown origin .   . . . from Stewart Coffin's   3 Pairs   puzzle .
Not only because this is a very small puzzle, but also because of the slippery plastic edges of the 'pairs' of each of the three sticks, this little simple-looking burr affords an extremely high level of frustrating dexterity in controlling the puzzle during assembly .   In fact, I have to cheat by tacking pieces of masking tape to certain areas .

Star Czech . . . . . 12-pc Lucite 'stars'
Yet another great work of art from my good friend Pavel Curtis.

An excerpt from  Pavel's Puzzle Blog states : "I decided that the pieces would rotate into position, using some kind of interlocking, hook-shaped protrusions on the edges of each face; that would still entail fairly wide (deep?) hooks, due to the shallow angle, but avoid any piece deformation during assembly."

Small version of the Japanese Crystal as found on the Web, or Bits & Pieces' The Great Pagoda, or Pentangle's Woodchuck .

Four Cubes

Mag-Nif Corp. has the same puzzle, but with more quality .

Multi Cross

This is someone's version of Pentangle's wooden Squirrel's Cage .


This is someone's version of Mag-Nif's Curious Cross . . . Reiss Games' Torment.


It has 14 pieces and the base .   Because it does have a base, this puzzle is only considered as partially interlocking, using the base to keep it together .

Knot   One of the best in the lot .

Similar to Cleverwood's kumiki Round Flower burr !

Fancy Square

This is Cleverwood's version of a kumiki Squashed Blossom .


Although this is a non-interlocking puzzle, I have added it to my list because it's a very nice 3D pentomino version .


The Molecule Puzzle   . . . injected-molded version of Stewart Coffin's wood original of the Altekreuse puzzle .   This one's a hot item . . . it's got heat fins on it . (not part of the Geo-Logic line, but still made by Skor-Mor).



Not quite a symmetrical shape . . . a couple of odd parts make it slightly amorphous ! (a hybrid from mixing parts of the regular names in the series).
