With a roll of the dice, the biggest little city in the world delivered big for Donald Trump - helping Nevada push the presidential hopeful one step closer to the White House.
But with big turnout - 42,000 more Republicans than caucused in 2012 - there were big problems for dozens of people, as many as 40 in Washoe County alone.
"We had the a binder for all of the precincts where they sign in and cast their ballot that was a little bit off from the main binder when registering," Victoria Crockett said.
She was the caucus site coordinator at Reno high school.
"They were just in a different page, issues with alphabetical order. Anyone not on the list was still given a provisional ballot that they were allowed to cast," said Adam Khan, chairman of the Washoe county republican party.
They got that ballot, If they wanted to wait around for them to arrive. Some voters just left. The Republican National Committee is now investigating.
FOX40 went to the registrar of voters to get some answers.
Luanne Cutler says she's never seen such an active registration period for a caucus.
"The Silver State saw a gold rush of interested folks signing up to participate - 3,000 republicans in just the last 30 days," she said.
It was a lot for Cutler's person staff to process.
And while some at caucus sites have suggested discrepancies might have been caused by late ads to the rolls after the February 13th deadline, the registrar says the party was responsible for taking the data she sent to the state and breaking it down into precinct books.
"Each county in the state uploads their database every night to the state," explained Cutler. "As of that cut off date nothing else has been put in."
Controversy, yes. But for Trump, it's putting no tarnish on his Silver State win.
