You've thrown a 7by7 matrix at us, some of the 49 locations
containing weird numbers, some blank, one with greenish edges;
then we're to find a missing tile? Are you joking?
Hahaha, I'm sorry! Those are my thoughts exactly too. This matrix is part of a campus wide game of-sorts. The missing tile I'm looking for is the one with the green edges.
If you can't find anything it's fine, I was just wondering if there was a simple pattern I was missing.
