The final “symbol” challenge is the 6X6 sudoku as predicted. I had thought that the chalice would be the sixth symbol, but instead a key, which we’ve never seen before, was used.
The question today required intimate knowledge of a very specific passage from a book. And provided a link to Google book search which was, in fact, very helpful.
Anyone know where I can find anymore of these symbol sudoku type logic puzzles…I’m addicted now
