Grant’s New Year’s Resolution was to submit 365 puzzles this year and he is still pretty much on pace. This is a huge quantity of puzzles to test, so his submissions pile up most weeks. When I do get to them, I often wonder how I am ever going to use most of these puzzles.

This week is a collection just from Grant’s early August submissions (spanning a roughly 10 day period). Unusual sizes and themes, but 100% Foxger. I hope you enjoy them.

Monday: Slitherlink
Tuesday: Masyu
Wednesday: Battleships
Thursday: Pentominous
Friday: Cross the Streams
Saturday: Fillomino

The bonus puzzle for our high-level supporters will be a Fillomino by Grant Fikes.
