**Tantalizer 1: ???** / ??? — *[missing]*

This list shows which puzzles I have been able to track down. If a puzzle is marked as *[incomplete]*, *[missing]* or is completely absent from the list then I have not yet acquired a source for that puzzle. I would appreciate any help with finding the missing puzzles. If possible I would prefer a photo or scan of the puzzle direct from a physical copy of the magazine, but a transcription of the puzzle text is the next best thing.

This is the most comprehensive listing I have seen in any listing of teasers

Thanks. I’ll keep adding “classic” Enigma puzzles as I find them. Although I try not to put up more than one a day, to avoid flooding people who want to have a go at them all. So it will be a few years before I have them all (if I can find sources for them all).

Your listing is growing gradually and as a paper and pencil teaser solver I can manage to attempt only couple of them a week which means decades of trying to solve them with a lot of fun.

A teaser a week keeps the neurologist away!

Lots of appreciation for your invaluable work you accomplish

Having just completed all the Sunday Times Teasers from 2325 onwards, I was concerned that the rest of my retirement might be bereft of easily accessible similar challenges. However Brian Gladman pointed me to your HUGE collection of Enigma variations. What a wonderful future your hard work will guarantee.

Thanks. I plan to keep posting Enigma puzzles as I track down back issues of New Scientist (and when I get a reliable internet connection).

If you want to post any solutions or comments please feel free to.

Jim, as it took so very long to get a tellafoam line you’re clearly living somewhere in the Amazon basin, so it won’t be easy for you to get to Brissl public library. Therefore I’ve put some of the early 1200s in my Dropbox:

https://www.dropbox.com/s/wvaouvv2p12yzf2/Enigma12.doc?dl=0

Any use? Do you want earlier ones?

This page (“List of Enigma Puzzles”) basically shows the puzzles that I’ve been able to source so far. If the puzzle is listed on this page then I’ve been able to find the text of the puzzle. Some of them I only have a partial problem statement for, these are marked “[incomplete]”.

The puzzles before 1990 I have been able to transcribe from Google Books archive, quite a lot of the more recent ones I’ve been able to source from the archive on the New Scientist web site (although some of these are missing diagrams), and from the rec.puzzles Usenet newsgroup.

The rest I plan to get from back issues of New Scientist. I transcribed Enigmas from 1207 – 1295 (although somehow I missed 1234 and 1264) last time I went to Bristol Central Library.

So I’ve still got to find quite a lot of puzzles. I’m currently missing most of the puzzles from 545 (published in 1990) up to 1206 (published in 2003) – so I’ve got around 650 to source.

I welcome any help in sourcing the missing puzzles. Photographs of pages of New Scientist with the missing puzzles on are particularly useful. I will transcribe them. But any pointers that will allow me to complete the archive are useful.

Brilliant site. Am working forward from the oldest. Please could you check the listed link to Enigma 193 6 Jan ’83, as it seems to be leading to a different puzzle (no.1322)?

Thanks for pointing out the problem – it should be fixed now.

I hope you find the site useful, and do feel free to share any comments or insights on the problems you try.

This site of Enigmas has been and will be the largest source of brain teasers I have ever come accross. The more additions the better until we have the full list of 1780 enigmas as long as our worldly life permits , even so there is the following generations who can show interest.

I again very much appreciate Jim and his valuable friends for their contributions not only in terms of puzzles themselves but also their solutions.

Well done for hosting these excellent puzzles. It is a pity New Scientist no longer publish them. Where do the puzzle authors now publish? Keep up the good work.

Jim, I have Tantalizer no. 226 to 378 (Jan. 1972 to Dec. 1974) in a big (133MB) PDF file. If you are interested, please let me know where to send it to.

At the moment I’m still working on the Enigma puzzles. I’m nearly half way through the archive of all Enigmas published, so I’ve still got around 900 to go. Which is going to take several years to get through. I have thought that once I’d finished Enigma – if I still have the energy and inclination – I would make a start on 80 “Puzzles” and the 500 “Tantalizers”, which I would be able to transcribe from the Google Books archive of New Scientists. That would probably last another few years.

So, I am interested, but I probably won’t get around to using them for some time.

I’ll drop you an email.
