The Quandary

Two movements are required to separate the two pieces. The
small piece can only be removed from one side of the large piece.
The other side is a dead end.
The Sting

The puzzle has a dead end, so if you have done
'something' to your puzzle, you need to get the
pieces back to their original position and start
again. The key to the puzzle is Gaps 1 and 2.
Manoeuvre the two pieces so that these two gaps
are next to each other. If you then slide the gaps
past each other, the puzzle will, at least in theory,
separate.

The Enigma

Two movements are required to separate the two pieces. The
first movement is quite simple. The second movement to finally
separate the pieces is much more complicated. With all metal
bar puzzles the secret always lies at the end of the bars as this is
where the pieces will come apart.
The Menace

This puzzle is likely to overwhelm even the most accomplished
puzzlers. The solution is very simple, but difficult to find. The
pieces obviously slide apart along the gap where the ends of
the rods meet. It is getting the puzzle into the correct position so
that this can be done that is the real challenge.

As if this wasn't enough, the puzzle can be put back together
two different ways. This means that you can understand the
solution perfectly and solve the puzzle with your eyes shut- but
if the puzzle is put back together back to front, you will have
tostart all over again.
Professor Mind Muddlers Puzzle

There is a ‘dead end’ in your puzzle. If you have done something,
but the pieces have not come apart, you need to get your puzzle
back to its original position and start again. For a clue to get the
two pieces back together again, you have to put two points into
two loops!

Professor Head Spinners Puzzle

Each ring is permanently connected to a loop of string. Then two
of these rings have been tied together. Your clue is that each string loop will not fit over the opposite ring, but it can fit over its own ring.

Professor Brain Bafflers Puzzle

This puzzle is much easier to get back together than it is to separate.
To get them back together, place all four ‘ends’ so they are touching
each other and slide the pieces together. Unfortunately, we can’t
think of a good clue for separating the pieces, so we’ll just have to wish you luck!

Professor Sense Sizzlers Puzzle

Hold the two pieces, one in each hand, at Points 1 and 2.
Then wiggle!

Boomerang

Concentrate on the knot around the larger metal ring. It all stems
from here! Only one of the two small metal rings needs to be used
to solve this puzzle.

The most effective way to solve this puzzle is to spend a minute
simply looking at it. This is far more likely to bring success than
fiddling around using trial and error.

Last Nail in the Coffin

Two moves are required to separate the nails, so if your puzzle
has changed position, you will be at the half way stage.
Considering that you are dealing with just two bent nails, it is
amazing how few people will ever understand the inner workings
of these two pieces of hardware. Holding one nail still at all times
will help you reach this end.

Quandary

Two movements are required to separate the two pieces. The
small piece can only be removed from one side of the large piece.
The other side is a dead end.

Dead Ringer

This puzzle can be separated into three parts, each part being a
ring attached to a loop of string. The secret to solving this puzzle
is to pass a loop of string over its own metal ring. Remember every move you make, as getting the metal rings apart is difficult enough, but this puzzle is more difficult again to get back to its original position.

Tricky Triangle

The first thing to notice is that the smaller metal ring will
fit through the rectangular shape of the triangular frame,
and the larger metal ring will not. The smaller ring will
have to travel around the whole section of the metal
frame before it will become free from the puzzle.

The Claws

The key to The Claws is to get your head around the first
move. If the three parts are held in the position illustrated,
the first move consists of passing one ‘claw’ through
another ‘claw’. Once this is done you can you move onto
the much simpler job of separating the links. Memorise
the first move, as it will really help you when you are trying
to get the pieces back together again.

The Switch

Where do we start with this one?!

The first and most important clue is to keep the small ring
on the metal bar at all times. Once the ring is slipped off the
bar on either side, the knot of cord around this ring can be
altered into a different knot. If you are finding it difficult to
get your puzzle back to its original position this could be
why. However, regardless of the state of the knot, the
puzzle can still be solved.

The second clue is to point out that you need to move one
ring across to meet the other via the string, not via the metal bar.

The Ring Leader

Although it does not look very complicated, The Ring Leader
is one of the greatest challenges known to the puzzling world!

On the most basic level, notice the following: Each ring has a
loop of string attached to it. To separate the 4 string loops, the
loops have to be moved ‘over their own ring’… in a ridiculously
complicated sequence…

This is the only puzzle we sell that when asked ‘show us how it’s
done then?’ we reply ‘can’t be bothered – it’ll take to long!’

The Mosquito

The ring has to be set free from the 'U' shaped section. The secret is to find the one section of the puzzle where the the ring can be moved past this shape. Do not waste time trying to find the answer in the middle part of the main triangular shape.
The Fish

The handle must first be removed from the fishes 'intestines' and then finally from the main body of the fish. To separate, start manoeuvring the handle around the central rings. To reattach, start on the ring on the outer rim of the puzzle by the fishes back.
Gridlock

The handle needs to by worked out from the centre of the 'grid', one step at a time. Work out how to move past each of the four rings in sequence. To reattach, start on the outer most ring and move in towards the centre of the puzzle from there.
The Whale

To either separate or reattach the handle, place the wooden bead through the metal ring before you start. The handle must pass over the whales 'eye' twice to solve (or reattach) the puzzle.
The Trap

This puzzle has a unique solution which is very difficult to find, but the solution is not complicated at all. Look for an unexpected little twist as only one deft move is required to free the handle. Do not waste your time concentrating on the area around the wooden ball or the area around the metal ring.
The Skelter

A number of moves are required before the ring will come free from The Skelter. It is the sequence you need to master to understand this puzzle. Note that the 'clip' part can come lose and this must be done to find the
solution.
The X-Ray

First the heart must be set free of the smaller looped section. This is the most difficult movement to do successfully. Then the heart can be removed from the larger looped section - in comparison a much simpler job.
