Patron Puzzles for Philanthropy: Magnum Opus Snake Crisscross

This update to the Patron Puzzles for Philanthropy initiative is to announce the Magnus Opus Snake Crisscross! It's yours for a charitable donation of US$5. It's just one single puzzle, but it's huuuuuuuuuuge, with over 300 entries waiting to be solved. Don't know what a Snake Crisscross is? Wordy Wednesday #262 is a pretty good example of one. A bit too difficult? Here is the easier version, and here is the answer. If you enjoyed that puzzle but wish it were much bigger, then give the Magnum Opus Snake Crisscross a try for many hours of entertainment! You will get four files: a hard version of the puzzle with no snake boundaries given, an easy version of the puzzle with all snake boundaries given, a list of all 300+ clue answers, and the filled-in solution grid.

As a reminder, this is a charity initiative. Please e-mail me (glmathgrantATgmailDOTcom) a copy of your charitable receipt to my local food bank, the Food Bank of West Central Texas, to receive this puzzle pack. (It must be a new donation, dated no earlier than one day before you email me.) Click here for a list of all of the puzzle packs in this initiative. Happy solving!
