Japam - Las Vegas?

Las Vegas? I must have taken a wrong turn in Albuquerque. Or maybe not, it's the Las, Vegas Pachinko Parlor (I'm not sure why there's a comma in the name). Pachinko is sort of a Japanese slot machine that uses ball bearings as part of the game play. I'm not really sure how they work. It seems popular because the Pachinko Parlors seem to be everywhere, but I've never meet anyone who say that they play Pachinko.
