This site is a companion site to Enigmatic Code (which collects Enigma puzzles originally published in New Scientist and their solutions). You might want to read the [ About ] and [ Notes ] pages there.

The site is for discussing and posting notes and solutions to the Teaser puzzles (formerly Brainteaser and Brain-Teaser) published in The Sunday Times.

Primarily it is focussed on archiving old puzzles, but I also put up new puzzles when they become available. (Although I don’t reveal the answers for prize puzzles before the entry deadline has passed).

My current sources are:

Here is a summary of published books of Teaser puzzles that I am aware of.

If there are other Teaser 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
