The royalties are as follows: $0.24 on Amazon US, 1 penny (about $0.015) UK,
and 20 euro cents (about $0.22) EU.

The idea was to make these books as accessible as possible (so no, in this case
not a lot of "topping up", but that is intentional).

Just to make sure people don't feel they have to get the books for the points, I'll drop that option starting the February issue.

For those who have not joined Amazon Prime, shipping costs more than the magazine. Hopefully the magazines will be available indefinitely so that they can be bundled into other orders.

Thank you for the new magazine, I am sure it will be a new challenge as usual, one per month is a hard responsibility (I would have rather suggested one every other month, i.e., but now it's late).

I vote for the idea of awarding points for the difficult ones, in the Calcudoku site (30 per magazine seems OK, one per day, but in this case I would clearly stablish a totally different daily limit for these puzzles, so that the puzzles of the non-periodic books can be sent at the same time, and in order to recover the puzzles of the old magazines).

With respect to the price of the books, ..., perhaps you shoud think of the idea of prepearing new editions, see what is happennig for instance in amazon.es with the "101 Advanced Puzzles" first edition, http://www.amazon.es/Calcudoku-Advanced ... atrick+min , the books brand new around 66 euros and the used books around 56 [thumbsup] [thumbsup] .

Not sure why that link is showing those prices, this one:

http://www.amazon.es/CalcuDoku-101-Adva ... 144614349X

shows the regular price.

(and that's also the link from the "Books" page)

Edit 1: yes, I'll probably increase the daily book puzzle limit from 1 to 2.

Edit 2: I sent an inquiry to Amazon about these two pages with different prices.
Edit 3: Amazon confirmed that this was an error, and merged the two pages. Apparently
"Sometimes, when a book is listed by Marketplace sellers, it receives its own Detail page instead of being correctly listed under the original Amazon sales page.".
I suppose it is in their (the other sellers') interest to make the book look rare [glare]

Would prefer book puzzles with points and not just for the most difficult ones [smile] !

This may be a minor digression, but I've quite liked the puzzles with exponential and modulo operators. Perhaps we could extend this to puzzles with floor, ceiling or log operators as possible variants.

Interesting ideas, thanks [thumbup]

So division with floor/ceiling (assuming that's what you mean).

For log there are limited options it looks like, e.g. clue is "4 log" in a 16x16 puzzle, answer must be 2 and 16,
because log (base 2) of 16 = 4 ?

OMG!!!.....Pardon my ignorance, but what does a floor or a ceiling have to do with Math and I always thought a log was something you burned in a fireplace [huh]

Yes, that's what I had in mind, i.e. floor(9/5=1.8) = 1 and ceiling(9/5=1.8) = 2. With ceilings/floors, there are definitely a lot of combinations.

While logs are a bit of a stretch, I though they might add an extra dimension to other puzzles. I think it would work, if, for example, the clue was "0 log", then you would know that it contained a 1. Or in let's say a 9x9 puzzle with clues like "2 log", there would be two combinations - (2,4) and (3, 9) - for a two-celled region. You could possibly have a three-celled region with "1 log" and combinations like (2,3,8) and (2,2,4) (log_3(log_2(8)) = 1; log_2(log_2(4))=1) in the same spirit as you've done exponentials where we read from right to left. I do agree that logs would work best in larger puzzles - but I think a few creative things can be done.

The floor function takes a number, x, and rounds it down to the largest integer less than or equal to x; the ceiling function takes a number, x, and rounds it up to the smallest integer greater than or equal to x.

The logarithm is quite natural if you're familiar with exponentials - it is the inverse operation, i.e. exp(log(x)) = log(exp(x)) = x (if real-valued, x>0). But, like taking an exponential, it depends on the base. You might by abuse of notation (this is not used!) say exp_2(5) = 2^5 = 32, whence log_2(32) = 5.
