Note that our solving widget/fave button is being fixed over this week and may temporarily be inaccessible; hopefully after the update is complete the issue that was keeping some people from logging in will be resolved. We will share more info when we know all functionality is working again.

This past week’s set of Tapa puzzles are collected in this PDF and the solutions are in this PDF.

The daily solution videos are on the posts and also linked below. We’ve been getting some helpful feedback on what you like about these videos as well as things we can be doing differently; please feel free to share your own comments as we continue to make these. We will eventually be making tutorial videos for how to use Penpa-Edit for each style, but as the interfaces are still being improved we have not done this for any genre yet.

This upcoming week will feature Sudoku puzzles and variations. We also expect to be releasing The Art of Sudoku 2 next Sunday. This long-awaited book features 180 hand-crafted sudoku puzzles, including 60 classic Sudoku, 20 Tight Fit Sudoku, 20 Consecutive Pairs Sudoku, 20 Even/Odd Sudoku, 20 Thermo-Sudoku, 20 Arrow Sudoku, and a variety section with 20 other Sudoku of different styles. We’ll be selling it as a complete collection or as three partial packs split out by sections (Classic only; Tight Fit + Consecutive + Even/Odd; Thermo- + Arrow + Other).

Today is the last day to submit an answer to Prasanna’s 200th puzzle submission contest. We’ll be back with a contest summary and list of winners later in the week (no later than Sunday the 21st).

Today we will also have a new Sunday Stumper (Anti-Pi Sudoku by Serkan Yürekli) as another bonus puzzle which will post in a few minutes.

The past Variety puzzle week of Even Rows and Columns puzzles are collected in this PDF and the solutions are in this PDF.

We’re starting to try releasing the solving videos the day after the puzzle posts, and will continue that this week although the blog entry may not get updated as routinely. So please subscribe to our Youtube channel if you want to always see the latest solution video. For the week, here are the six solving videos:

This upcoming week will feature Tapa puzzles and variations.

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.

Last week’s set of Balance Loop puzzles is collected in this PDF and the solutions are in this PDF. If you enjoyed these puzzles, our latest ebook Balance Loop by Prasanna Seshadri and Murat Can Tonta was just added to our web store with 55 puzzles including 34 regular Balance Loops, 20 variations across five styles, and one giant hybrid at the end.

Again I have made solving videos in Penpa-Edit for all of the Balance Loops from this week so check these out if you are still learning this interesting puzzle style:

This upcoming week features TomTom puzzles as well as two surprises from Prasanna Seshadri (including one coming very soon today that will be our first “contest puzzle” in awhile).

Last week’s set of Star Battle puzzles is collected in this PDF and the solutions are in this PDF. If you enjoyed these puzzles, look for more Star Battles in our store.

Now that I’m routinely checking all our puzzles in Penpa-Edit and playing with solving interfaces, I once again filmed my solves for all the puzzles in the week which may offer different tips on Star Battle and also show some of the custom interfaces that can be used during solving. (Getting edge/border notation to be a default and not just a custom option is still a goal).

This upcoming week features Balance Loop puzzles, and at the end of the week we will add a new Balance Loop e-book by Prasanna Seshadri and Murat Can Tonta to our e-store. We’ll may also have another Sunday surprise or two coming up so stay tuned.

We hope you enjoyed JinHoo Ahn’s debut week as a new puzzlemaster on GMPuzzles. You can find the six puzzle variations in this PDF and the solutions for each variation in this PDF. Like all our debut weeks, there was something extra going on here in each of the puzzles from Monday to Saturday. If you haven’t found anything special yet, keep looking, or read through these hints:

1. Find something in common between the six puzzles
2. What if what was most in common was ignored?
3. The week features six variations on puzzles, but you may be able to solve them another way.
4. Remove all of the instructions after the phrase “Instead of their usual meaning”. These puzzles all double as classic versions of the same style.

Solving videos for the six puzzles are below. All of the videos include info on the Easter Eggs for the week in the second part of each video, so if you want to avoid spoilers you should be prepared to pause the video at the spoiler warning:

We will have one more bonus puzzle from JinHoo for Valentine’s Day, posting very soon (it does not have an extra Easter Egg). This coming week features Star Battle puzzles, which was the genre for JinHoo Ahn’s first book with us.

You can find all the puzzles from our Kurotto week in this PDF and the solutions are all grouped in this PDF. If you enjoyed this style, please check out the book Kurotto by Prasanna Seshadri that we published at the end of last year.

We have three solving videos this week using our Penpa-Edit solving interface. This starts with the Kurotto (Connections) by Prasanna Seshadri:

Next is a video for the “Pairs” Kurotto by Swaroop Guggilam:

Finally, we have a solving video for the Saturday “Empty Columns” Kurotto by Prasanna Seshadri:

This coming week is a special one. For the first time in over a year we will be adding a new contributing puzzlemaster to the site. In this debut week for JinHoo Ahn, you’ll find a set of variations where the clues — instead of their usual meaning — have a new twist to think about.

You can find all the puzzles from our Araf week in this PDF and the solutions are all grouped in this PDF. We will be releasing a new Araf book from Serkan Yürekli in the next day or so; come back for more info.

We have three solving videos this week using our Penpa-Edit solving interface. This starts with the Araf (Line) by Serkan Yürekli:

Next is a video for the “Oh Nine” Araf by Jeffrey Bardon:

Finally, we have a solving video for the Saturday “Cyclops” Araf by Serkan Yürekli:

This coming week will feature Kurotto puzzles, which we recently featured in an e-book by Prasanna Seshadri.

You can find all the puzzles from our most recent Sudoku week in this PDF and the solutions are all grouped in this PDF.

We have two solving videos on paper for the Friday Sudoku by Ashish Kumar and the Saturday Arrow Sudoku by Swaroop Guggilam:

This coming week will feature Araf puzzles. If you are unfamiliar with this style (particularly how to solve in Penpa-Edit), this earlier solving video may be helpful for the week.

You can find all the puzzles (through Saturday’s Skyscrapers) from our 2021 debut week in this PDF and the solutions are all grouped in this PDF. The solution for the Sunday Stumper will be released next week.

With this being our first week with Penpa-Edit as a digital solving option, I used it for five of the puzzles (Monday-Friday) while making a paper solution video for the Saturday puzzle. We won’t be making videos for every single puzzle this year, but given the variety week and some more challenging than usual puzzles this seemed a good week to cover everything including showing some different ways Penpa-Edit can be used.

If you have any comments on these videos including our use of Penpa-Edit in them, please share them here.

Our second week of 2021 will feature Sudoku puzzles and variations.
