Re: Solution

I found it easiest to make my own jigsaw pieces and try them in the various locations.
It's a bit of trial and error but if you follow the arrow rules and the no-touch rule (diagonals are ok)
you'll find the correct positions.

Spoiler

4 of the 7 pieces are rotated so the letters are sideways or upside down, no pieces are flipped

Spoiler

write down the letters in the shaded squares in order and you will get a four word question

Spoiler

the code is the answer to this question

Re: Solution

As an aside, this is I think the only puzzle in the book that is based around a standard logic puzzle grid type, albeit one rarely seen. It usually has pentominos, and you can find a few examples at https://www.gmpuzzles.com/blog/tag/pentopia/ - and elsewhere on the web.

Just like the ones linked above, the puzzle in the book solves logically step-by-step - you just need to eliminate squares that can't be reached, and work out which tetrominos can still fit in each space.

You can find lots more of the tetromino version of the puzzle in The Tetris Puzzle Book. Amazon UK:  https://www.amazon.co.uk/Tetris-Puzzle- … 787392368/. Amazon US: https://www.amazon.com/Tetris-Puzzles-G … 1645170519. Piece of trivia: in that book they are called 'tetriminoes', since that's the official Tetris name for a piece.

So the best way to solve it is by creating jigsaw pieces and give it a go??

That would be giving the answer away. It's pretty simple once you make the pieces as there is only one way they will fit and meet the rules

Re: Solution

You can solve it purely as a logic puzzle:

Spoiler

Because pieces can't touch, and arrows point at the nearest piece, you can eliminate a lot of options - and you have a finite set of pieces, so after a relatively small number of deductions you will narrow down the possibilities quite quickly.

Pieces can be rotated but not flipped, and are each used once.

But you can also use a mix of logic and word puzzle deductions, at least to help reassure you you're on the right route:

Spoiler

Letters on shaded squares should be read from left-to-right, top-to-bottom once the pieces are placed. So any piece placement that results in nonsense on shaded squares is definitely wrong.

Spoiler

The first letters on shaded squares are W and H, which form the start of a question. Knowing this you can place a piece on the top row immediately, given one of the arrows. But I do recommend solving logically.

I believe I came up with the correct ? but all the answers I have tried ( and there were many) were unsuccessful.

Re: Solution

If you enter the text revealed by the puzzle, what does the website response say? Or, to put it another way, what is the answer to the question being asked?

Or if you've already got that far, which actually I think is what you mean now I reread your question, then for the actual answer...

Spoiler

you'll need to look at other pages.

In particular...

Spoiler

Look for a term used in two previous puzzles. They also share a symbol.

Spoiler

Content in codes 33 and 39 might both be helpful. There is more than just a symbol that links them.

Re: Solution

I actually tried that word early on but used the singular of the word instead of the plural. smile
I am really enjoying the puzzles!  I like that there are some that I can see the way to get the answer a little easier and that there are others that are a bit more challenging.
I also like that you are always quick to reply to my pleas for help!!!!!! Thank you so much! You are awesome!

Re: Solution

Thank you! smile  And I've now made it give a more useful response if you enter it in the singular too.
