I have solved one puzzle, and I cannot find any more clues

[Timdogg]

Did you get any further? I have:

the six number box, sd(used), red, blue and green book

Don't have the clue for it, just the box....

[tipper75]

Nope, where is the clue for the six number box? But I've been doing other stuff

[Timdogg]

Out,

Look at the wall with all books, note the groups of gray books, should be smooth sailing from there, if you have all three books.

Okay then, you need the color puzzle,

look at the books just above it and follow the pattern after red

If you still need a book

there's one left rear of desk

[tipper75]

That is the puzzle I solved, missing a book, I guess:

[Purp]

Wow, I have

three white books (used), screwdriver (used), key (used--Thanks for the hint, Tim), and now just have the six number box and a book.

[Timdogg]

Purp, did you look at the top of desk clue? it will tell you where you use the last book

[Purp]

Yes, I did. I figured out the clue and escaped. Tipper, where are you?

[Timdogg]

he went to bed, under the desk I think!

[Yvonne]

Stuck with the box that needs a code and I haven't seen a clue for that one.
Done all other things with a little help from Tim about the gray buttons.

POP did it for me again

if you've opened the 2 doors, use the word from the left door

look at the picture with the alphabet

and I'm out

[Fishaholic]

out with no help...visual observations a key...really enjoyed this one.

I've seen the brown book - can't read what is on it. Seen the 3 slots. Have no idea. I don't recall a picture on anything. I've opened the area to right of desk and item on wall across from the desk. Thought I understood one clue but I was wrong. Have not located the key. Maybe need to restart?

I went to email and took pup out. then did 3 slots (light bulb finially came on). Tried safe which needs 3 digits - hmm.. that is still on my list of things to do. LOL math problem - redid and that worked. All down hill from there
out

[Timdogg]

You need three books for safe code one book is

hidden behind desk to the bottom left

If you have the gray book from safe

put it in the book shelve on the left, if you look at clue on top of desk you will see where to put it

for six digit box: find the #'s that correspond with the letters

K, E and Y on the chart that it between the two now open bookshelves
