1. I assumed that if the cover and the writing were the same colour, then we wouldn't be able to read the writing.

2. I assumed that they could be different shades of the same color if it was allowed.

3. Puzzle 13: I should have stated that the colour of the writing is different from the colour of the cover. Otherwise, and both gabi and sluggy have noted, there would be multiple solutions. There could always be a supplementary puzzle about working out all possible solutions if writing and cover could be the same colour, but that would be more difficult to check.

Both gabi and sluggy have sent me the answer I was expecting, with cover and writing in different colours.

4. Knocka, do you mean puzzle "15" in your previous post? When I looked at the actual puzzle 13, it sort of just blew me away (figuratively) with all the information.

Hmmm, I'm still having trouble with puzzle four lol, is it asking for "who cliffs"?

Thanks, anderson. I should have said puzzle 15. I have made the correction in the quote.

Puzzle 4 is not asking for "who cliffs".

6. One letter can make quite a difference. I'll be asking for the original to be edited. There was C missing in efficacious which means that the coding was definitely not efficacious. There are only 24 hours in the day.

We'll drink a drink a drink to
Lily the pink a pink a pink

The saviour of the human race
For she invented medicinal compound
Most efficaCious in every case

I think it should say
23 8 15 23 8 5 14 23 8 25

knocka will have to look at it when she arises and make the determination
