Sunday Update and Solutions

Our recent variety mix week (at “Starter Pack” level difficulty) is gathered together in this PDF and the solutions are in this PDF. The Wednesday TomTom by me is indicative of the puzzles in our latest book, Starter Pack 3: TomTom, which was released this morning in our e-store.

The daily solution videos are on the posts and linked below:

This coming week will feature Nurikabe puzzles and variations.

New e-book – Starter Pack 3: TomTom

We’re excited to announce the publication of the third volume of our “Starter Pack” series, Starter Pack 3: TomTom. Like the rest of our Starter Packs, this collection contains a set of easy to medium (Monday to Wednesday) puzzles perfect for solvers wanting to learn a new style or for experienced solvers who want familiar, but not impossible, challenges.

This is a particularly exciting collection for me as it is my first time coming back to make a TomTom collection in many years. While the cover art features my famous first calcudoku from 3/3/09, the book itself contains 36 original puzzles, 18 with operations and 18 without operations. There are also a set of links to Penpa-Edit versions for online solving with answer/error checking enabled.

The next Starter Packs will feature Slitherlink and Star Battle, and we welcome your continued feedback on this series.
