I'm a pretty avid puzzler and I would just like to say that I am very
impressed by the your Gridworks puzzle. It's so simple and yet still finds
new ways to get me thinkin'. Theres so much more to be done with the
concept, and I look forward to a new one every week. Great job!
-A fan

Question: I
have downloaded your Logic Problems 12...the printable version on your
website. Where can I find the solutions to check my answers?
Thanks.

Question:
Hello-
Thank you so much for providing great logic puzzles-- my kids really enjoy
them. We downloaded the pdf file of "X2" and are wondering if there are
solutions for these puzzles?
Thanks!
Jamie
Answer:
Back in February, 2002, when our Logic Problems Monthly Interactive
project just started, the idea was to provide our visitors with an
interactive version of the grid-based logic puzzles online. We with our
partner site
PuzzlersParadise.com didn't consider the printable version to
be included into the project, making it "purely" interactive. As the
project evolved we discovered a lot of our visitors appreciated the idea
to have both options - interactive and printable - included into the
project. Thus, starting from the project's 2nd year the PDF printable
version became the basic feature along with the interactive one.
In order to compensate the lack of the printable versions for the first 24
Logic Problems of the 1st year, we decided to produce two PDF puzzle
packs:
Logic Problems 12 - a dozen of Logic Problems published at
PuzzlersParadise.com in the 1st year of the project.
Logic Problems X2 - a dozen of Logic Problems published at our site in the
1st year of the project.
None of our PDF printable versions for Logic Problems includes the
solutions. The same concerns both packs. Just like the solution to any
Logic Problem can be found directly on its interactive page online, the
solutions to all puzzles in those two packs can be found online while
searching through the two pages (24 Logic Problems from the 1st year of
the project):
Finding the respective title from the packs on those two pages and
clicking it, leads to its respective interactive version online - either
at our site or at
PuzzlersParadise.com. For each interactive version there is the
Solution button right below the text with the clues. Clicking it reveals
the respective solution.
Question: I
tried on the Internet to see if I could find any either 500 or 1000 piece
puzzles of Hummingbirds and could not bring up any picture of them to
order.
Question:
Hello,
I've got a KenKen question. For the 4x4 version, do you know how many
different puzzles can be created?
In other words, how many non-identical arrangements of the digits 1, 2, 3,
4 can exist?
Thanks for any help you can give.
Bill.
Answer:
This is a good question indeed! There are 576 Latin Squares of 4x4. More
information on this can be found
here.
At the end of 2008 our site in cooperation with
Strimko.com launched a new puzzle concept based on Latin
Squares - STRIMKO. It is a weekly interactive project. Each week three new
STRIMKO challenges can be played at our site
here
and three other ones directly at
Strimko.com.

Wayne B.
Answer:
Unfortunately, our parent company ThinkFun doesn't carry jigsaw puzzles.
At the same time the posed question what could be the upper limit in the
number of pieces for a jigsaw puzzle is very interesting. If you have any
ideas, please,
drop us a
line. Thank you!

Question: You
are stuck in a room with no windows and no doors. There is a hole in the
floor about a foot deep and just wider than the diameter of a table tennis
ball. There is a table tennis ball at the bottom of the hole. You have a
fork, a wrench and a long, thin plastic wire. How do you get the ball out
of the hole?
Deepak K. G.
Answer: We would like to
present this fun brainteaser to our visitors. Please, give it a try. The
funniest thing about it is that how one can ever get into a room which has
neither windows nor doors (?!). Think about this fact as a hint :).
Anyway, if your are stuck in getting on the core, take a look

Have fun!

Question: I
am looking for a puzzle that has six squares and 9 lines. Another words
you have to draw a line from each square to the other without crossing a
line.
Do you know of this and possibly what it is called?

Answer: We suspect this
might be a related puzzle to the one which is sometimes referred to as
Walls
& Lines but honestly we are not quite sure.
170 Unicursals: 2 Squares with Crosses &
1 Triangle
Question:
Dear puzzle people :)
For about 4 years - on and off - I've been trying to figure out how to
trace - without repeating lines or lifting pencil off paper - the
following figure: two squares - one on top of the other - with a cross in
each, and a triangle on the very top. It's also been called a two-story
house with a roof and two crosses. I've been told that there is at least
one way of tracing this. I am completely stumped and I've given up... can
you please give me the solution (if there is one)?
I must come across as very stupid - not being able to figure out a random
puzzle... but oh well.
PS - I've attached a word document with a picture of what it's meant to
look like... :)
Thanks for your time!
~ Véra Ada.
Answer: Unfortunately
the pattern is impossible to draw. More explanations can be found in
items
#51 and
#86.
The theory explaining which patterns can be drawn in one continuous line
and which can't, is at the
solution page to
The Unicursal Marathon puzzle.
Question: I came
across this puzzle and am stumped.
A farmer wanted to start a small orchard and went to the nursery to
purchase 10 fruit trees. The man at the nursery told him that if he could
plant the trees in five rows with four trees in each row, he could have
the trees at no charge.
Hopefully you can answer this for us. Thanks in advance.
Answer: Fortunately, we
have this puzzle in our
Puzzle Playground. It is called
10-in-5-Rows. There is also a link to solution in it.
