Sunday update with solutions and schedule for next week

Our first 2020 week of puzzles can be found in this PDF and the solutions are all grouped in this PDF and have been linked to the individual posts.

This week’s video talkthrough is for Elyot Grant’s interesting Fillomino puzzle.

Next week we will be featuring Sudoku puzzles including some variations.


It is great to be back, which means we met our goals of relaunching our e-book store alongside our weekly web puzzles. For the whole month of June, we have a 20% discount on all titles in the shop (automatically applied at checkout) so please check out the store if you want to purchase some puzzle PDFs.

There are more updates to come later in the year as we strive to improve the GMPuzzles community experience. One of those areas to is expand our Sunday content, including a return of our “Ask Dr. Sudoku” column. One topic we will plan to discuss soon is related to a comment from this week’s Star Battle puzzle — how should we integrate electronic solving options to our web posts and books. If you have other questions or suggested topics for us, please share as comments and we’ll select some for future posts.

We also are overdue to post our “Best Puzzles of 2019”, and we will start that next Sunday with our Best Sudoku of 2019. But as an early preview, and as the extra solution video for this week, we wanted to link to one of our very best (and trickiest) puzzles of 2019, this Fillomino from John Bulten from January 2019. In case you missed it, please try it now; tips if you get stuck are in the solution video below.
