Pinball Hall of Fame

The Pinball Hall of Fame is a 25,000-square-foot standalone building near the Welcome to Fabulous Las Vegas sign holding hundreds of playable pinball and arcade machines: the world's largest pinball collection open to the public, running from 1950s wood-rails to modern tables. Entry is completely free. You pay per game, a quarter on the older machines, 50 cents on the '90s classics and up to a dollar on the newest, with tokens four to the dollar. It's a 501(c)(3) nonprofit, and once operating costs are covered the rest goes to the Salvation Army and other non-denominational charities.

Practicalities that matter: bring cash, because nothing on the floor swipes a card and the change machines want bills; there's no kitchen beyond vending machines, though you can carry your own food in; and a few hundred machines clanging at once make it genuinely loud, so weekday mornings are the calm window. The building sits at the south end of the Strip past the airport turnoff, so you'll drive or rideshare, and the free lot - a Vegas rarity - is for museum visitors only rather than free parking for the Welcome sign, and it's enforced. Machines are antiques, so a few are always down for repair, and the resident techs fix them in the open where you can watch.
