This is a Nurikabe puzzle, with a twist. Some numbers have been replaced with letters. Same letters represent same numbers, and different letters represent different numbers. The assignment of letters to numbers is up to you to determine.
This is (probably) not a return to the weekly posting yet; it’s a one-off I made before the WPC and wanted to post.
When a call for making a puzzle to decorate the US team shirt went out, I made this, while motris made this. As can be clearly seen I wasn’t thinking a whole lot about aesthetics in making mine, so there was a clear deserving winner for getting put on the shirt. Still, the puzzle came out well and is worth posting.
On another note: is everyone else seeing the gridlines as not showing up in the scaled thumbnail above in a very ugly way? It happened to Space Probes in my USPC set too. Geez, after over 3 years this is the first time I’ve been really upset with how WordPress is treating me.
