This site is a companion site to Enigmatic Code (which collects Enigma puzzles originally published in New Scientist and their solutions).
It is for discussing and posting notes and solutions to Sunday Times Brainteaser puzzles.
Primarily it is focussed on archiving old puzzles, but I also put up new puzzles when they become available.
My current sources are:
- Puzzles from 1961 (the first numbered Teaser puzzle) onwards.
- Puzzles from 1974 – 1979 selected for the book The Sunday Times Book of Brain Teasers (1982).
- Puzzles from 1991 – 2000 selected for the book Brainteasers (2002).
- Puzzles from 2013 onwards, that I solved at the time.
- Other puzzles that I find interesting.
If there are other puzzles you would like me to include please get in touch.
To be notified when new puzzles are posted enter your email in the Subscribe box on the right.
Feel free to join in, either by leaving a comment (with a program if you like), linking to your own solution, or by rating puzzles (or just “liking” them). If you want to leave a general comment about the site, please do so below. Any kind of feedback is useful in encouraging me to keep the site going!
If you use this site as a source of puzzles please include a link back to the puzzle on this site.
Here are some other sites that focus on Sunday Times Brainteaser puzzles:
- Sunday Times Teasers — a discussion site for Sunday Times Teasers (the previous site [link] had Teasers going back to 2010)
- PuzzlingInPython — Brian’s site for Python solutions to Sunday Times Teasers

Hello Jim,
There are some teasers listed which can’t be accessed yet like “Teaser 2544: Neighbourly nonprimes / 26th June 2011”. Is there a special reason why there are not yet published?
I saw Brian had a nice solution for this one on his site.

@Frits: The puzzles that are not linked are ones that I have transcribed, but not posted yet.
I try and post puzzles between Enigmatic Code and S2T2 at a rate of 1 a day, so that there is a small “working set” of currently puzzles which I have recently looked at in play.
I’m happy to look out any particular puzzle as requested. I can post Teaser 2544 on Thursday.

@Jim,
A – Any news on better searching in WordPress sites?
B – Is it possible to have a link to more than eight “Recent Comments”?
C – As I normally spend 6 months in SE Asia and don’t always have internet access I am wondering if you could put somewhere a big zip file with all Enigmatic Code and S2T2 puzzles (for manual solving). I don’t want to overload your sites by using a website copier.
I wish you a Merry Christmas

A – I’m not sure there is much I can do to change the way the WordPress search works. Although I have noticed that on S2T2 the search seems to also search comments as well as posts (on Enigmatic Code it only seems to search posts).
B – If you use an RSS reader the Comments Feed [ https://s2t2.home.blog/comments/feed/ ] has more comments in it (20 at the moment, but I’ve just upped it to the last 100).
C – I don’t have a version of the puzzles other than on the website. (I have backup XML file, but I think that is to load the site onto another WordPress instance). I think it would be OK to use a crawler to make a local copy of the sites, just don’t do it too aggressively, otherwise WordPress might take countermeasures. I think there are about 2158 puzzles between the sites. When I archived the old Google Groups site for Sunday Times Teasers I used Opera’s “Save Page as PDF …”, but there were only a few hundred pages to archive there.
Happy New Year!
