Sunday Update and Solutions

For those that missed it, we released a new e-book TomTom last Sunday. It is a great collection from four of our puzzlemasters for this number placement style. We are working to complete two 25-puzzle Sudoku variation packs this month and will then release our first edition of a quarterly puzzle mix magazine late in August. As we’re finding we are on track to release 12 books this year (about one a month), we’re considering restarting a subscription option for people to get some/all of our book content at a discount. Please watch this space for more info in the coming months and, as always, share any feedback you have with us on our puzzle collections.

Our past week of Slitherlink puzzles is collected in this PDF and the solutions are in this PDF. There are more Slitherlink puzzles in these e-books in our store.

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.
