"One game when I played him it was an absolute clobber," said Wolfberg. "I think he used all his letters six times. I'd never seen that done before."

Mead described Logan as "soft-spoken," saying that he was modest and reserved about winning.

He added that Logan often wears math T-shirts and plays Scrabble with his shoes off "cause that's how he's most comfortable."

Logan said he enjoys Scrabble because "it's really an aesthetic experience very much."

"I never really took to chess very much which is more traditional," he said.

Logan said he likes "putting a few letters between words to make other words," and that he has made many good friends playing Scrabble.

Logan said he plans to continue competing, possibly entering the Canadian championship this fall.

Logan went to Princeton University at the age of 16 and graduated in 1995.

He hopes to teach a tutorial on the arithmetic of elliptic curves this fall
