There is still another week to submit answers to Prasanna’s 200th puzzle submission contest. That challenging puzzle as well as the 30th Birthday Surprise would have filled the week on their own, but we also had six great TomTom puzzles for you. The TomTom puzzles are collected in this PDF and the solutions are in this PDF.

I have made solving videos in Penpa-Edit for all of the TomToms from this week so check these out if you got stuck or want to learn more ways to think about these puzzles:

This upcoming week features a variety mix of puzzles, all with the same new constraint of “Even Rows and Columns”. We hope that you enjoy it. Also watch out on 3/14 for our next Sunday Stumper.

Throughout 2021, we are working to have our older catalog of puzzles updated to have digital solving options and to also have solution PDFs everywhere.

On the PDF front, we have recently added another 18 months of solutions to the site and currently have answers for all puzzles posted going backwards to February 2016.

We are also now taking individual puzzle types and putting them all into Penpa-Edit to enable digital solving. The first puzzle style we have completed is Kurotto and all 27 of our prior Kurotto have digital versions with automatic solution checking online. We will eventually “reintroduce” these puzzles with a better set of “How To” videos, a curation of our favorites, and a better web-flow than just blog pages for solvers who want to binge on one of our styles. For now, if you want to try more of this shading puzzle style please click through the Kurotto archives.

Finally, a lot of people have been asking about our solving widget (i.e., FAVE/SOLVE button) that has had login issues for several months due to browser security updates as it was hosted externally. We are nearing completion of an update to host this ourselves, and will share another update here at the end of the month. With the solving tracking, online solving, and other solutions coming together we hope that the solving experience for GMPuzzles in 2021 is greatly improved. Please share your feedback with us on how we can do even better.
