Just released to our e-store is this TomTom collection. Our puzzlemasters Ashish Kumar, JinHoo Ahn, Murat Can Tonta, and Serkan Yürekli have worked together to create 63 incredible hand-crafted challenges. Your mind will need to stretch a lot to solve the 42 classic TomToms, 20 variations (4 each in 5 different styles), and the giant TomTom (Samurai) puzzle that concludes the book. If you enjoy mathematical and logical challenges, this book will be perfect for you.

GMPuzzles 2021 Objectives and Key Results: Mid-year check in

2021 continues to be a year of transition and growth for GMPuzzles. Having brought Serkan Yürekli on-board as Managing Editor last year, and getting more support from the rest of our team, we’ve had the opportunity this year to focus on several different parts of our publishing business. At the start of the year I set our some objectives and key results for GMPuzzles. While this was just a set of internal targets, I wanted to write today to share our goals with our audience, suggest how we think we are doing, and get your feedback on anything more we need to be doing to meet our objectives.


All Kurotto on Penpa-Edit, and Solutions / Tracker Update

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.

Penpa Update, and one Star Battle video revisited

Thanks to the great support of Swaroop Guggilam, we have already updated our Penpa-Edit beta to have new solving functionality for Star Battle. In addition to the left click on a cell to place a star, and right click (or right click and drag) to mark X’s, you can now right click on an edge or corner of a cell to place a dot clue. Putting in a star in a cell touching a dot will make the dot go away so your notes clean up after themselves. You may need to clear downloaded files from your browser cache to get the latest version of the solving interface to show up, but we hope you enjoy this improvement as much as we do.

While there was nothing “wrong” with our first solving video for the Pinwheel puzzle, it used some trickier steps than it needed to. So we made a new YouTube video to highlight the new solving interface tool for Star Battle, as well as a simpler path to get around the Pinwheel:

New e-book: Araf by Serkan Yürekli

Our plan is to release at least 1 new e-book each month in 2021. Our first release is a really great title: Araf by Serkan Yürekli, with more region division puzzles like we just posted this past week on the site.

This book is a full exploration of Araf from Serkan, with lots of clever puzzles and Aha moments. There are a total of 50 hand-crafted puzzles, including 12 puzzles across three variations and a giant Araf at the end. Check it out now in our e-store.

New e-book: Star Battle by JinHoo Ahn

JinHoo Ahn has shared a lot of great web puzzles this year (some that will likely be very competitive for Best of 2020), so I’m quite excited to announce the release of our first book of puzzles from this talented designer, Star Battle.

This book is a collection of 50 Star Battle puzzles, including 15 variations, that have some very nice visual themes and interesting logic. The difficulty ranges from easy to hard, and includes ten 3-star 15×15 puzzles (two of which are variations) and a massive 6-star 30×30 puzzle to finish. Check it out now in our e-store.

New E-Book: Plenty O’ Pentominous 3 by Grant Fikes and Murat Can Tonta

Our solvers have found Pentominous to be a really great region division puzzle, so we are excited to announce the third volume in our e-book series, Plenty O’ Pentominous 3, has just been released on our e-store. Grant Fikes and Murat Can Tonta are back with another incredible set of Pentominous puzzles, including 8 Pentominous (Borders) variations.

If you are new to this puzzle type, here are our easiest Pentominous to get try out.
