Magic Wheelz


Magic Wheelz is a puzzle producd by Clown Games, which is not a new name in puzzle manufacturer country.

This puzzle is strongly reminding of the numerous snake-puzzles. It consists of 16 linked circles, which can be folded in several shapes. Folding angles are 45, 90, 135 etc degrees. They have various coulours on one side, and are black/grey on the reverse.

“That must be super-duper easy,” was my first thought when I saw all the unique colours. But they found a small trick to make to make it a bit interesting: in the exercises they depicted just some of the colours. Puzzle exercises with the grey/black sides are a bit more esthetically pleasant, but arent too difficult either.

It came cheap, less than 4 euro, and if you like it, here are some more exercises:

1) flower

2) Abstract figure

May mazes amaze?


Mazes or Labyrinths are among the oldest problems in human history. The word labyrinth comes straight from the Greek word λαβύρινθος, pronounced labyrinthos. This post is intended to give a brief overview, it is impossible to capture all knowledge on mazes in a single book, let alone in a single blog post.

The oldest labyrinth known was an elaborate structure designed and built by the legendary artificer Daedalus for King Minos of Crete at Knossos. Its function was to hold the Minotaur, a mythical creature that was half man and half bull and was eventually killed by the Athenian hero Theseus. Daedalus had made the Labyrinth so cunningly that he himself could barely escape it after he built it.[1] Theseus was aided by Ariadne, who provided him with a skein of thread, literally the “clew”, or “clue”, so he could find his way out again.

Another ancient Greek example is scratched on the back of clay accounting tablet at Pylos, Greece, in approx 1200 BC. See for example https://bloggermymaze.files.wordpress.com/2013/06/kre-mini.jpg

In the late Renaissance garden mazes became popular, and this popularity has remained over the centuries.

A word about the terminology: I regard the words “maze” and “labyrinth” as synonyms. Some say a maze should be branched, and a labyrinth unicursal that is, having one path from start to finish, but I find insufficient historical proof for such usage. After all, the labyrinth in the Greek story above must have been branched, else why should he need a thread to get out? In this post i will concentrate on branched mazes, as unicursal mazes may be fascinating for some people, but this blog is about puzzles, and I don’t see a unicursal labyrinth as a puzzle. Greek labyrinths have also appeared on coins, as early as 430 B.C.

The coin depicted is a Silver stater, Knossos, 300-270 BC. Νumismatic Museum, Athens, Greece.

According to the German language wikipedia, there have been four phases in garden labyrinths:
Late renaissance period
Often detailed by flowers, and from a terrace the visitors could look over the entire maze, solving it with their eyes. Most of these labyrinths no longer exists, though some of their plans have been handed down the ages.
The earliest gardens with fences come up at the end of this period, such as the gardens designed by the protestant preacher Johann Peschel in 1576 in the town Grüningen.

The German language wikipedia shows this example of a stone-path labyrinth at Castle Reichenfels

And another example:

Baroque
The love of art and complexity produced some beautiful garden mazes. An old example is at Hampton Court.

English gardens
This period started in the early 18th century. The mazes looked naturally, with rocks, sand, bushes and trees.

Mazes are still popular. Warren Stokes maintains a blog posting one new maze a day. With his permission, here is one of his creations:

This post took a long time. I started writing it in May, 2012. I staid dormant for years. It as only when I created a book with mazes for children for our grandson, that I remembered this post.

Squirrels go nuts


When I returned from Burkina Faso early January, my wife presented me with a copy of Smart Game’s new “Squirrels go Nuts!” puzzle.

I already had several of Smart Games puzzles, such as “IQ link” and “IQ Fit”, and they usually provide a decent amount of puzzles, starting easy and gradually toughening. This one is no different.

The puzzle consists of a tray with four holes, and four squirrels who have to drop their acorn into one of the four holes. Your task is to slide the squirrels over the board so that the acorns are dropped into a hole.

The puzzle comes with a booklet with 60 problems, and you may wish to skip the first half of them – personally I found them ridiculously easy, and no, I’m not a super genius.

Plastic snake


Last week I purchased another snake. It is not the first one I obtained, and if its price wasn’t ridiculously low at 4 euro, it would have remained in the shop at The Hague (or was it Utrecht?) Central station. The producer is listed as Clown Games.

You can read about the previous one here.

The packaging consisted of plastic, which I had to cup open.


At 4 euro it was so cheap that wondered if it would fall apart before i finished the booklet with examples, but it actually turned out to be sturdy, and even to a degree where it requires some force to turn.

The little instruction leaflet contained just 4 figures:

These can indeed be constructed:

There are numerous figures one can make with the snake. Credits for the following figures mostly go to my wife Jos and our daughter Margreet:
