It’s basically a cryptogram game, based on the Enigma Device. Java-based flash game, puzzle is almost always a quote of some kind. There are two new puzzles daily, an easier one and a harder one. The main colors are yellow, magenta, and black.
I had thought it was actually called “Enigma,” but apparently it’s not, that’s a whole different game. Maybe it’s something else that starts with “E.”
Anybody know?
