According to the league's official figures, 45,719 fans walked through the Allegiant Stadium gates on Saturday. That's precisely 510 more than last year.
Since the NRL's first expedition to America two years ago, it's clear that the concept has grown.
Cracking the American market is proving predictably difficult.
Saturday's matches were all shown on Fox Sports 2 for "continuity", after one was at least elevated to free-to-air status.
Those who did tune in saw the best 89-minute-and-55-second advertisement for rugby league on US soil so far, with Canterbury's thrilling 15-14 golden-point win over St George Illawarra.
Newcastle's 28-18 win over North Queensland was also captivating in its own way, with the Cowboys twice threatening to come over the top of the Knights.
But even if rugby league never captures America, the sport is at least making Vegas a home for at least one week a year.
The sight of thousands of fans streaming in over the bridge that connects Allegiant Stadium to the Las Vegas strip before kick off will have given officials cause for hope.
The same could be said for the estimated crowd of 16,000 that took over downtown Las Vegas on Thursday night, in the league's biggest fan event world over.
Hot dog stores in some parts of the stadium were sold out by halftime of the first NRL game on Saturday.
Equally exhausted was some of the league's merchandise, with the smallest gridiron-style NRL jerseys left in the main merchandise store before NRL kick off being 3XL.
There was a feeling among some club executives going into this week that year three is the sweet spot for Vegas.
The concept has been refined, but the hype has not yet died down.
Whether the NRL can make it any bigger is now the real question, with ARL Commission chairman Peter V'landys having declared this week the event is here to stay beyond when the current contract expires in 2028.
Melbourne, Parramatta, Wests Tigers, Gold Coast and the Dolphins and 18th club Perth are the remaining franchises to pick from for next year, before teams and their fans are asked to return.
But the NRL already has its sights set further afield, with V'landys having detailed a three-year plan to work towards a global round for the league by the end of this decade.
The league is known to be keen on London, with Wembley Stadium likely to be added as soon as next year as part of a graduated expansion of overseas matches.
Miami, Hong Kong, China and the UAE are other potential venues, although the expansion into the Middle East may be somewhat clouded given current developments.
Wherever the NRL does go next, the English Super League will be part of it.
V'landys wants each global event to host a Super League match and an NRL double-header, mimicking the current Vegas schedule.
And it would be hard to argue with that structure, with Hull KR and Leeds fans flooding the Las Vegas strip this week ahead of the Rhinos' 58-6 demolition of the Robins.
All the while, Vegas is set to remain as the league's "anchor event".
And given TV ratings at home are traditionally strong for the season kick off in the city, if this is as good as it gets, that may well be enough for the NRL.
