Not all of the puzzles you will view on this page will have solution links.
I reserved that choice to those that appear to be the most challenging in the high difficulty rating.

As much as I admire Puzzlemaster for their achievement of visual creativity, and have the greatest respect for their resourcefulness in creating the solutions for this line, there are those few instances where certain of their
solutions may appear ambiguous to the less initiated .

I admit that I myself have been challenged from the confusion resulting from failure to
understand some of their schematics.

So, to that end, I've enhanced some of the original solutions to better acquaint the viewer with a more familiar understanding of what they are trying to achieve visually.

Let me remind the reader here that there are but a very select few of these not-so-familiar solutions.

cast NEWS

According to the description on PuzzleMaster's  webpage  for this puzzle, "I came up with the idea for this puzzle when I was 19 years old. It just came to me during a stroll home in the snow; it's truly a creation of my youth. Unfortunately, saying anything here about its construction would give away how to solve it. I certainly can't disappoint the fans that have come to expect frustratingly difficult puzzles from me. Besides, the fans that refuse to accept any kind of hint are those who make me the happiest! The key word is 'needle'."

cast H & H . . . from eBay (seller: riscoutmaster)

There are two 'H' pieces that need to be separated. Out of a scale between 1 to 10, this is a gruelling 9. Very difficult.

Notice the RH piece; this is the main orientating piece to the solution.
It has Hanayama's name stamped onto it.

The second pic are the same two pieces from the backside.

cast COIL

According to the fine folks at  PuzzleMaster , "It appears like a box-like lump with a hole in it, but is actually comprised of two coiled up virtually identical pieces. You must try to take it apart by sliding and rotating the pieces. Although the pieces are angular in shape, they can be rotated in unexpected ways, making their movements quite intriguing. The theme of the puzzle is Loops."

cast CYLINDER

According to the fine folks at PuzzleMaster, "As the name implies, there is a hidden trick inside the cylinder puzzle.  There is absolutely no hint or clue on how to start from the outside appearance.  If there is one hint that we can provide, it is to go about it as if you were cracking open a safe.  Enjoy finding the solution while pretending to be a spy cracking open a safe with a shaken not stirred martini by your side.  The theme is "lock".

You can see the video solution on YouTube  here

(This video is what helped me the most.   AWESOME !   I always thought that the 3 vertical pcs were identical.
Only 2 are identical . . . the third is the 'key' to the whole solution. The video will explain why.)

Once you find where the inside ridge voids are within the 2 outer rings, put masking tape on the outside of both rings (as long as the voids are -- so that each end of the tape strips coincide with each end of the inside ridges). This way, you always know where they are throughout the rest of the solution.

note: just to add some helpful hints here . . . . .

* each of the 3 pieces are 1/3 of a circle (120º)

* after finding the synchronized position for the voids inside the 2 rings, while holding the 2 rings from moving with one hand, with thumb and forefinger of the other hand (thumb underneath the rings, forefinger on top), rotate the 3 pieces until a piece suddenly drops down partially through the rings . . . holding both rings from rotating, place a finger inside the rings and move all 3 pieces counter-clockwise to the next 120º location .

If the pieces resist moving, try the next piece to drop, again placing a finger inside the rings and try to move all 3 pieces counter-clockwise to the next 120º location .

Again, if resistance is met, try the 3rd piece. If after trying all 3 pieces, and the entire group resists moving, you have the assembly upside down.

Turn the puzzle over and try again. You may want to mark an arrow on the masking tape so that it indicates where the 'top' of the puzzle is supposed to be . . . or . . . put a tiny piece of masking tape on top of the 'key' piece (off to the side from where you'll ne touching it).

* after continuing to hold the synchronized position for the voids inside the 2 rings, while holding the 2 rings from moving with one hand, with thumb and forefinger of the other hand (thumb underneath the rings, forefinger on top), again rotate the 3 pieces until a piece suddenly drops down partially through the rings . . . this will be your 'key' piece (but, not the first piece to be removed)

* after the 'key' piece partially drops, continuing to hold both rings from rotating, place a finger inside the rings and move all 3 pieces counter-clockwise to the next 120º location (inline with the void position of the 2 rings -- where the masking tape is)

* the piece (one of the twins) to the left of the 'key' piece will drop further down from the 'key' piece

* rotate the rings counter-clockwise again, only about halfway towards the next 120º location . . . the twin piece will now disengage from the assembly . . . the other 2 pieces can now easily be removed from the assembly.














cast GALAXY

According to the fine folks at PuzzleMaster, "Like the swirling shape of the galaxy…that is why this puzzle was named Galaxy.

It is not that difficult to solve but one becomes totally mesmerized by the pieces that move freely. It is more difficult to put them back together than to take them apart. Take a good look at how the pieces move when taking them apart so you can put them back together again.

The theme is knot and was designed by Bram Cohen from the United States."

cast DELTA . . . from Amazon seller Santa Trading Japan

                                                                                             partial opening >>>

According to the fine folks at  PuzzleMaster  , "It is the brain-child of Hong Kong native Kyoo Wong who, with the eye of an engineer, has worked on a number of cast puzzles. While simple in form, its geometry somehow challenges and stirs up our creativity. The theme is the number three."

note: this is the point one wants to get at -- where the 3 points form a triangular space -- after which, even /\ though it being a tight fit, with a little jiggling and constant pull-apart pressure, the points slide past each other to separate the pieces, as noted further below.

. . . . . pieces

Why is it called Delta? It closely resembles the fourth capital letter of the Greek alphabet Δ
(an Isosceles Triangle -- 2 sides are equal in length, the base is shorter).
However, the puzzle is an Equilateral Triangle (all 3 sides are equal in length).

I guess the Hanayama folks decided it was close enough to give it the name 'Delta'.

Made of brass, it is finished with an aged bronzed look.
The appearance gives the puzzle a high quality appearance.
The size is small, but feels sturdy and comfortable to handle and maneuver.
It is triangular shaped, and measures 5.7 x 5 x 1cm (2.2" x 2" .4").

The Cast Delta really stands out by its simple and yet elegant design. Because the construction is brass, it unfortunately has that characteristic smell that it leaves in your hands. It does have an advantage, though, due to its rugged texture it hardly gets scratched, unlike some puzzles that have an extra coating finish.

Before attempting to solve it, the solution is thought to be a simple coordinate-motion technique . . . just separate the three pieces, pulling on them simultaneously. Upon noticing the hooks on each of the pieces, one immediately concludes that there is something else to it other than simply pulling on the pieces at the same time, although this is partly true. The ingenious part is, however, hidden from view inside the puzzle, so you need to figure out how the pieces must be separated.

All you can see is a slight view of the inside just a few millimeters long . . . and way inside, a small rod that fits into the hook on the end of each piece . . . . .
(once you've got the pieces separated, of course).

These rods most likely are the parts of the puzzle pieces that keep all 3 pieces together without just coming apart on its own.



A little fiddling separates the 3 pieces from their rods, but a further maneuver must be reached
(the center of the puzzle where one can see the tips of all 3 pieces (as noted by the left-hand pic)
-- formed into an
'equilateral triangle').

This is the crucial part that must be reached before further continuing trying to separate them.

Always holding 2 pieces at a time, if one position fails to separate all 3 pieces, rotate the puzzle to the next 2 holding pieces and try again.
(note: sometimes, you may want to use the forefinger of one of your hands to push against the 3rd piece while maneuvering the other 2 pieces . . . . .)



A little more fiddling and jiggling, and one will eventually find the 'sweet spot' . . . . .

Here, the triangle 'space' from above has finally been overcome, and movement is well on its way towards the '3-tip position' (below).





The tips of all 3 pieces are touching . . . and now, separation is finally ready to be achieved.

note: when separation is finally achieved, you will have noticed that hardly any force was needed at all, contrary to the opinions of some blogs.

Patience, perserverence and delicate maneuverings are all that are needed to achieve your goal here.
The puzzle is rated as a level 3/6

Along with what you've just read above to help compliment the entire solution, you can see the basic solution PuzzleMaster has put forth, with a little more explanation for clarity  here














cast Harmony . . . from eBay member desertskygifts2013

According to the fine folks at PuzzleMaster, "The “G clef” and “eighth note” intertwine and give off a beautiful note as if they’re playing music. The design, which does not resemble a puzzle at first glance, is beautiful to the eye as well as fun."
