The Development Team

The site was set up and initially run voluntarily by just one person, Andrew Sharpe. As the site has grown it has become unmanageable on my own. To help keep the site manageable while maintaining a high standard of puzzle a team of volunteers was formed in September 2018. They help by quality assuring puzzles, contributing to the writing of puzzles and solutions and other general help with the development of the site.

If you want to volunteer to help with the running of Puzzle of the Week please fill the form below. There's no commitment and even if you can check just a couple of puzzles a year then that's really useful!
