Here are the first solutions and thoughts, spoiler tags removed (first from ConMan, then my reply and additions):

It certainly is, and it isn't subtle at all. Because it deliberately mis-spells "subtle" as sudtle to avoid using the letter "b" for the entire puzzle statement, as it is indeed the answer.

Further confirmed by the pattern that all other letters in the alphabet appear at least once.

You should read the first puzzle first, since it contains general advice or instructions for solving the other puzzles (these are all instructions we get). Again, the answer we are looking for should be in the form of one letter, either upper case or lower case.

I've got nothing for this one. Random thoughts:

1. Just taking boxes with a letter as black and those without as white, the squares don't seem to join into any meaningful shape in any configuration.

2. There are both vowels and consonants represented, and likewise a bunch of other common categorisations of letters (open vs closed, straight vs curved)

3. Presumably the locations of letters are significant, but similarly there's no obvious pattern there - nothing suggesting that columns or rows or boxes are splitting the letters somehow.

4. What unique letters are there? A, B x 2, C x 2, D, H x 2, K x 2, N, P, R x 3, S, T x 2, U, Z

5. No letter other than R appears more than twice, and never twice in the same box.

6. B appears in the same position in the two left-hand boxes, but no other letter does.

7. K and R appear in the same relative position in the two right-hand boxes, but no other pair of letters do, and H is not in the same position relative to them in those boxes (nor are B and C in the same relative position in their boxes). So probably nothing involving aligning the boxes via common letters.

Your thoughts are worth mentioning. Adding a little more about the positions of letters. Let's designate the boxes in each 3 by 3 square thus:

We can fill in all the letters that appear in each box:

1. Of all 9 boxes only 1 and 4 are populated only once.

2. 7 is populated twice by the same letter, so we see that if we laid all 4 squares one over the other only the first column would be readable and match perfectly (the middle box would also have a readable 'R' over the 'P').

3. Only boxes 3, 5, 7 (the / diagonal) are populated exactly twice.

Something potentially significant comes when we consider the positions of the letters in the alphabet. We have:

Code: Select all

` 1 26`

18 11 18 20

2 3 14 8

3 4 11 18

16 21

2 20 19 8

1. For each square, max - min equal:

2. The sum of all numbers from all 4 squares equals 243=3
