We are excited to announce that The Art of Sudoku 2 is now released in our e-store. This collection of 180 hand-crafted sudoku and variations from sixteen authors was many years in the making, but certainly worth the wait. The entire collection is available for $10 in our e-store, and there are three $4 subsections available: A) = 60 Classic Sudoku; B) = 20 Tight Fit / 20 Consecutive Pairs / 20 Even-Odd Sudoku; C) = 20 Thermo-Sudoku / 20 Arrow Sudoku / 20 Other Variations.
We have been continuing to make some updates to the website. First, on the Penpa side, all of the “classic sudoku” in our archives now have an online solving option. This is the second puzzle, after Kurotto, to be fully digitized, and Star Battle is being worked on now. When we are through with digitizing more styles, we will be reintroducing them here including making some How To videos for using Penpa for these genres.
Also, our solve tracker on each puzzle post has been updated to now be hosted on our site. This update should fix the login problems people have reported over the last six+ months; please tell us if you run into any issues with it, including not seeing your past fave/solve history.
The daily solution videos are on the posts and also linked below.
This upcoming week will feature Pentominous puzzles.
