premise: Most casinos have at least some kind of arcade, but the true high-scorer is GameWorks (Tel. 702/895-7626), next to the MGM Grand, with 47,000 sq ft (4371 sq m) of games (more than 250) from traditional pin-ball outposts to high-tech diversions.
hypothesis: Most casinos have arcades but the MGM Grand sends people to Gameworks, which is very impressive.
