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.
