I got Andy these 2 puzzles where the pieces have the alphabet on one side and numbers on the other side. One set has black lettering and one has white. At one point today, we were missing one piece. I was looking thru the remaining pieces and he told me the one we needed was green with a white V and 22 on the back. That’s when I noticed that the pieces were laid out with the numbers showing but he was putting together the alphabet side. So I tested him. I took several random pieces. Showed him one side and asked what was on the other side switching between letters and numbers and he got every single one right with hardly any hesitation. Is that genius or savant?
