Other than the rare nickel slot machines (which only exists in old school Las Vegas casinos), the best payout comes from the $5 slot machine, according to the Las Vegas Review-Journal. Casinos had a 5.46% win percentage in 2024.

That said, high odds are really the main draw of Circus Circus. The facility itself is the most gritty of the famous Las Vegas casinos. If you don't mind the less luxurious side of the Sin City gambling scene, head to the north end of the Strip and try your luck at Circus Circus.
