Sporting events held at the 2016 Summer games from Rio de Janeiro have been the first since the 2000 Olympics in Sydney that bettors in Nevada could put their money on, though relatively few have.
State gambling regulators were previously against having wagers on what it considered amateur sports but Las Vegas bookmakers successfully lobbied them last year to change the policy.
Officials at the local sports books said they didn't expect a sweeping boon to business but that whatever action they've gotten, however little, has been better than nothing.
Basketball this summer has reigned supreme, as a steady number of bettors backed the familiar NBA stars dominating the men's Olympic games.
Soccer and golf were also among the more popular events that were wagered on.
The same can't be said of the more obscure sports that some sports books said they didn't get any bites on whatsoever.
The overall amounts seen per bet — $10 to $20 — for the Olympics have been peanuts compared to the record $132.5 million wagered in Nevada on this year's Super Bowl.
