Quick note that we’re migrating our webpages to use https instead of http and cleaning up other minor things as we enter 2017. The only major issue we’ve identified in going to https is with the solving applet hosted by thegriddle (to clarify: the way you input solutions and add favorites) which will not load unless http connections are allowed. We expect a fix to this issue in 2017 so that all content can be loaded securely.

If you encounter other site issues over the next week, please comment here or send a private message so we can address them as quickly as possible.

Our most recent week of Patron-requested puzzles can be found in this PDF.

For our last week of 2016, we are adding Carl Worth to our roster of contributing puzzlemasters. Carl has made some great guest contributions over the last two years, including to The Art of Puzzles 2, and was an author on the 2016 US Puzzle Championship. It is our pleasure to bring you Carl’s debut week, a rather challenging week featuring a new variation that combines Fillomino and Snake puzzles. Will you be able to solve all the puzzles?

Our supporters will also be receiving a bonus Star Battle by Carl Worth, access to puzzle solutions, and a PDF walkthrough of the Saturday puzzle. If you’d like to receive some of these special rewards, please click here for more info.

In the past week some of our patrons have also received the new e-books Logic Puzzles 101 by Grant Fikes, and Snake and Variations by Serkan Yürekli. We’ll be adding these books later this week so come back before the new year if you aren’t a grandmaster supporter but want to get these titles.
