Victor is good at the game but able to lose. Humans can use all 178,691 words that are allowable in North American Scrabble tournaments, but Victor is limited to 8,592 words taken from "The Adventures of Sherlock Holmes.”
During the game, and particularly if he is losing, Victor will come up with insults. These include: "Since you're human, I guess you think that's a pretty good move."
When a human played the word "mitering," earning a 50-point bonus for using all seven tiles: "I can't believe your feeble mind was able to play that word."
It is also good at catching out human opponents trying to pass words that are not in the dictionary: "This is not happy land of make believe. We only use real words," snarled Victor.
