I’ve been busy with a lot of things recently (house hunting, a larger role at Verily as I recently became the head of computational biology, getting back in “competition shape” for the upcoming World Puzzle Championship, finishing some new e-books for the site, training for a marathon for the first time in over a decade, …). What this means is that for the rest of the summer we’ll be going to a biweekly schedule with our free web content. Coming on the 17th will be our next “patrons week” with puzzles requested by our top patrons. And then on July 31st will come our next week highlighting a style from The Art of Puzzles 2. Thanks for your patience, and enjoy the great puzzles.

Theme: Happy Face

Author/Opus: This is the 280th puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Standard Spiral Galaxies rules.

[Copying the rules here as this is the first week: Divide the grid along the indicated lines into connected regions – “galaxies” – with rotational symmetry. Each cell must belong to one galaxy, and each galaxy must have exactly one circle at its center of rotational symmetry.]

Answer String: Enter the number of cells in each connected group (between bold lines) in the marked rows. Separate each row’s entry from the next with a comma. The example has the answer “2131,331”.

Time Standards (highlight to view): Grandmaster = 1:30, Master = 2:00, Expert = 4:00
