The Pinball Hall of Fame says it needs help keeping a roof over the museum’s head.

Founder Tim Arnold started an online campaign Friday in hopes of raising $200,000 to finish construction on the museum’s new Las Vegas Boulevard location.

The museum is still welcoming customers on East Tropicana Avenue, where it has sat for 11 years. The new location on Las Vegas Boulevard was expected to open in the spring, but Arnold is expected to vacate the Tropicana location by May 6, he wrote on the online fundraiser.

“The new building is now 96 percent finished, and we find that because (of) an almost total collapse of the tourist traffic in Las Vegas, we are going to fall short of having the money to finish,” Arnold wrote.
