New Jersey's head gaming regulator has taken responsibility for a sports betting glitch that cost Paddy Power Betfair's FanDuel Group $82,000 on a bet.

The regulator said that new internal company controls have been put in place to prevent similar future problems. 

In September, one extremely lucky person from New Jersey bet $110 on a Denver Broncos football game at the same moment that an error had incorrectly warped FanDuel's live-odds feed during a brief update. 

Initially, FanDuel said it would not pay out the whole $82,000 because it was an error. 

New Jersey gaming regulators investigated and FanDuel reversed its decision, saying it would make the full payout. 

"We're partners with FanDuel in many ways. Maybe it was our fault that that happened," David Rebuck, director of New Jersey's Division of Gaming Enforcement, said. 

"So I will take responsibility for that as head of the division," he said. "It should never have happened." 

The incident was "a bad hiccup for the state of New Jersey," he said. 

The US state is ahead of nearly all others in regulating and taxing sports wagers after a US Supreme Court decision in May threw open the door to any state that wants to legalize the activity. 

FanDuel is owned by Irish sportsbook operator Paddy Power Betfair. 

In this case, regulators first examined whether there might be a criminal conspiracy or some other type of fraud aimed at hurting the company, Rebuck said. 

But there was not. Instead, it was human error. 

"We felt that maybe we needed additional staff here at FanDuel to give us added protections for quality control to oversee what was being entered while the trading was being managed," Rebuck later told Reuters.

New Jersey gaming regulators have significant control over sports betting, with a catalog of approved sporting events and the ability to determine what sports bets are authorised in the state. 

The state also weighs in on companies' internal controls, which can include limits to the amount of money wagered and limited odds. 

Operators also have other layers of risk management, including people entering data. 

Regulators can decide whether there are "enough people doing the work so that they're not stressed and making mistakes," Rebuck said.
