We get lots of great submissions to GMPuzzles, most often on the hard end of the spectrum. This week will feature 6 different guest contributors with some unique and challenging puzzles (about 3 “Wednesdays” and about 3 “Saturdays” in difficulty):

Monday: Nurikabe by Swaroop Guggilam
Tuesday: Cave by Bryce Herdt
Wednesday: Tapa (Windows) by Jack Lance
Thursday: Thermo-Sudoku (Missing Bulbs) by Hans van Stippent
Friday: Fillomino by Carl Worth
Saturday: Slitherlink by Walker Anderson

Our supporters will also be receiving a bonus Pentominous from Grant Fikes, access to puzzle solutions, and a video walkthrough of the Saturday puzzle. If you’d like to receive some of these special rewards, please click here for more info.
