New e-book: Araf by Serkan Yürekli

0 Flares Filament.io 0 Flares ×

Our plan is to release at least 1 new e-book each month in 2021. Our first release is a really great title: Araf by Serkan Yürekli, with more region division puzzles like we just posted this past week on the site.

This book is a full exploration of Araf from Serkan, with lots of clever puzzles and Aha moments. There are a total of 50 hand-crafted puzzles, including 12 puzzles across three variations and a giant Araf at the end. Check it out now in our e-store.

    Does this e-book (and perhaps others later in the year) include linkouts to penpa-edit versions of the puzzles?

    • drsudoku says:

      No, it does not. We will announce if we do add penpa solving to any books but are hoping to have a different server-side implementation (with user accounts) of the puzzles before encoding our books — this is a long-term project we are still looking to resource.

    Thank you.

  • Carl says:

    Is this the first book which was not part of any of the previous Patreon rewards? Will there be a way to filter such books in your store?

  • drsudoku says:

    We haven’t had Patreon/subscriber rewards since end of 2019/start of 2020, so all books listed May 2020 or later on this page are new. (There are a few delayed titles like The Art of Sudoku 2 that will be coming out in 2021 where they will be sent to past Patreon members in some situations).
