Schedule for Next Week

This week we are featuring Pentominous, which is the style of our most recent puzzle e-book “Plenty o’ Pentominous” by Grant Fikes and Murat Can Tonta. If you enjoy this week of puzzles, please get this collection of 52 original puzzles including several 15×15 grids and one giant puzzle.

This week contains a few extras, including two extra puzzles on Friday and Saturday. There is also one easter egg hidden somewhere in this week’s puzzles which, if you find it, will tell you what word to enter here.

Master+ subscribers to the site are getting a bonus Pentominous by Thomas Snyder and a Cave (Pentominous) variation by Serkan Yürekli as well as images of the puzzle solutions. If you want to become a subscriber and get access to bonus puzzles, solutions, e-books, and other rewards, check out this page.

Site update

You can find our most recent week featuring Star Battle in this PDF.

After three straight weeks of puzzles, we are taking one week off (we will continue this 3:1 schedule for 2018). We’ll be back next week with a variety mix from our puzzlemasters.

Our Grandmaster subscribers are still getting puzzles today, receiving a Giant 20×36 Nurikabe puzzle by Murat Can Tonta and the “Plenty of Pentominous” e-book by Grant Fikes and Murat Can Tonta. We’ll be releasing this book on the website in a few weeks, but the easiest way to get all our puzzles is to sign up for a subscription.

Best of 2017: Region Division Puzzles

Here are our best Region Division puzzles of 2017, selected from the 42 web posts in this category (our second most frequent class of puzzle).

One of our theme weeks in 2017 was “Just One” with lots of puzzles using just the clue number 1. This Pentominous puzzle from Carl Worth was a very creative use of the just one rule, featuring the Roman numeral I, and was voted one of our best puzzles.

Another of the top puzzles was this Fillomino variation by Murat Can Tonta that required symmetric regions.

Our best Region Division puzzle of 2017 came from a guest constructor who is now a regular US puzzle team member: Walker Anderson (link to his blog). Walker cracks the “best of” listings a few times this year for his contributions, and this Cave puzzle had a really incredible logical flow.

This Week (and Year) on GMPuzzles

This week we’re going to feature our “Best of 2017” with the top puzzles as selected by you through the FAVE button. From Monday through Saturday we’ll be highlighting roughly three puzzles per category (region division, number placement, loop, …). We’ll also be releasing details on new subscription options for our fans, replacing the patronage model we’ve used in the past.

While this is a time for a lot of annual retrospectives, this past month also marked the 5 year anniversary of GMPuzzles. My initial business plan went out on 12/12/12 at 12:12:12 and our first post here was at the end of 2012 before New Year’s Eve. For those that have been solving from the start, and for those who joined later, thanks for supporting our puzzlemakers and our community by being a patron of the site, purchasing our books, or referring friends and family to our puzzles.

I’m incredibly proud that we’ve published about 2500 puzzles in these five years, including some phenomenal classics and cool variations, and have had 0 broken puzzles (with anything other than exactly 1 solution) despite being a hand-crafted puzzle company. I stopped keeping track of how often solvers have doubted us, but I think we are at least 100-0 when someone posts that one of our puzzles has a mistake. (We have had a couple typos in our blog posts and I’ll take the blame on the rare times when the answer entry was wrong but our puzzles have never been.)

Thinking back over five years, I judge that we have been very successful in highlighting great logic puzzle design and encouraging new designers to get into puzzle construction. However, we still have more to do to build a larger audience of solvers that appreciates hand-crafted logic puzzles. Some of our efforts this year will be to have more introductory titles/weeks. In our first year, we often had focus on single classic puzzle types in posted weeks and we will get back to that a little more during this year as well as trying to have more “easy” puzzles more regularly. A longer-term project is to reorganize our website. While we have a large backlog of puzzles in each style, it is hard for a person just discovering our blog to know where/how to start. We’re thinking through some user experience improvements for new solvers reaching the site and welcome any ideas you have.

In 2018, we are also going to work on scaling our publishing. I spent a lot of 2017 turning semi-automated processes into fully automated processes, including how we generate our puzzle art and our web posts. We just finished submission guidelines for all of our puzzles and contributors will receive these soon. I’m also very happy to announce that Serkan Yürekli will be joining me as an editor for our books and other puzzles which will add to our throughput.

We have several new books in mind for 2018, including the launch of a recurring sudoku publication with a mix of Classics and Variations which will be a great title for fans of sudoku, and several more e-books highlighting genres that haven’t been in books yet like Pentominous, Nanro, and Statue Park.

On a different note, we’re going to launch a “Puzzlemasters’ Workshop” title to highlight entirely new puzzles and variations. We get a lot of unusual variations submitted here, and they are hard to post on the web as one-offs. The goal of this title is to give authors enough space to develop an idea across several puzzles. The first edition, expected around midyear, will have a new style from each of our puzzlemasters and a few guests, with 6-10 puzzles in each new style. If this works, we’ll continue this series and open it up for other submissions as a way to continue to cultivate new puzzle design even while our web puzzles start to have a greater focus on “classics”.

Thanks for solving with GMPuzzles, and here’s to a great 2018,
Thomas

Here are our best Region Division puzzles of 2016, selected from the 39 web posts in this category.

While we didn’t have as many guest contributions in 2016 as in earlier years with the site, there were still some stand-out puzzles from our guests including this magnificent Cave by Bryce Herdt with Fibonacci Spiral theme.

Cave by Bryce Herdt

Another Cave, this time a Diagonal variation from Prasanna Seshadri, also got top marks from many solvers.

Carl Worth demonstrated the quality that earned him a contributing puzzlemaster position this year with a tough Fillomino puzzle with a dominoes theme.

The best Region Division puzzle this year though went to this combination of Pentominous and Star Battle by Grant Fikes that gave solvers a unique kind of logical challenge.
