Illegal online casinos are using Roblox, one of the most popular video games in the world, to draw children as young as 12 into online gambling, a Sky News investigation has found.

The unlicensed casinos allow children of any age to sign up using their Roblox accounts and bet their in-game currency (Robux) on games like slots and blackjack.
Winnings can be withdrawn as cryptocurrency - and then converted into real cash.
Roblox is one of the most popular video games in the world, with an estimated 80 million daily active users. Described by its CEO as a "digital playground," Roblox is particularly popular with children - 42% of its users are thought to be aged 12 or under.
Sky News spoke to one teenage Roblox user in the US who says he gambled around 15 million Robux (£150,000). He started using the sites aged just 14 - seven years below the legal age for gambling in his state.
"My mother tried to get me to stop, but I didn't," says Robert*. "I just liked the adrenaline of doing bigger and bigger bets."
He had no idea, he says, that he was committing a criminal offence.
"I just thought it was something you could do to make extra money," he says. "I didn't even know what gambling was."
Sky News' investigation focused on three of the largest Robux casinos - BloxFlip, Bloxmoon and RBLXWild. Altogether, the sites receive around 2.8 million visitors each month and facilitate millions of pounds worth of bets.
In response to Sky News' findings, the Gambling Commission has launched an urgent investigation into the Robux casinos and has blocked them from the UK.
"Criminals will always try and find new ways to exploit people, including children," the regulator's chief executive Andrew Rhodes told Sky News.
Sky News was able to access data from one of these casinos, Bloxmoon, showing that users have lost a total of $11.4m (£8.9m) on the website since it launched in late 2022.
The data includes bets placed on RBLXWild since July 2024, when this website was purchased by Bloxmoon.
Between April and October 2024 alone, users placed bets worth $22.3m. The casinos' owners paid out only $20.1m as winnings, keeping the remaining $2.2m as revenues. That's an average revenue of $10,281 (£8,149) per day.
Other casinos may be making even more money. Of the eight casinos identified by Sky News, the most popular is BloxFlip, which receives an average of 2.7 million visitors every month according to website analytics company SimilarWeb.
BloxFlip announced it was permanently shutting down less than 36 hours after Sky News presented its findings to the casino and to Roblox.
"The legal team representing Roblox has begun to apply pressure compelling us to close our platform," a co-owner of BloxFlip wrote in the casino's official chatroom.
"No more luring minors in and giving them addictions early," responded one user, who had bet more than 10 million Robux (£100,000) on the site.
A spokesperson for Roblox told Sky News that the casinos are "in no way endorsed or authorised by Roblox" and that the company has taken "numerous steps to disrupt their activity, which violates our Terms of Use".
"We have a dedicated group focused on identifying potentially fraudulent activity on Roblox and we work collaboratively with law enforcement authorities where possible to pursue the owners of such websites," the spokesperson said.
"Our efforts have met with some success, but we would welcome further law enforcement action and vigilance from web hosting providers to shut down sites like this."
Unlicensed casinos have 'no safeguards'
Robert says he started gambling on BloxFlip after seeing an advertisement on social media.
"At first I deposited around 100 Robux (£1) - just something small to try it out," he says.
"I lost it all. Then I deposited more to try to make up for it, which I lost again. Then I deposited more."
Soon, he was gambling with his friends every night.
One time, Robert says, a friend threatened to kill himself after losing 20,000 Robux (£200) on a single roulette spin. It wasn't clear if he was serious, but the group didn't want to get adults involved for fear of revealing their gambling habits.
"We just tried to calm him down ourselves," Robert recalls.
Dr Jane Rigbye, chief executive of underage gambling charity YGAM, says that unlicensed casinos have no safeguards in place. This means they are "potentially much more dangerous, both financially and psychologically," than regulated casinos.
"If children are exposed to gambling at an earlier age, they're more likely to experience difficulties with gambling later in life," she adds.
'Nobody cared'
Robert has no doubt that the websites' staff know many of their users are underage, based on conversations in the group's official chatroom on the social media platform Discord.
"There'd be people [in the Discord group] talking about their age in casual conversations with the moderators, the developers of the site," he says. "They didn't care. Nobody cared."
In the BloxFlip Discord users who have wagered at least a million Robux (£10,000) can apply for "Whale" status, giving them a special whale emoji next to their username. Users who have wagered at least 10 million Robux (£100,000) can apply for "Platinum Whale" status.
At least four Whales and two Platinum Whales have openly admitted to being underage in the Discord group.
"I was here since 12 [years old] lol I'm 14 now," wrote one user, whose screenshots show that he has bet at least 1.1 million Robux (£11,000) on the site.
Another user who is shown to have wagered at least 17.5 million Robux (£175,000), says he turned 16 in November.
He added: "Is it even [worse] that I'm an underage gambler and I have plat whale?!?!?!"
A staff member with the title "head of community" even acknowledged that one "Whale" was underage. After the user stated his height, the staff member said: "you are 14 right you probably got a bit to grow still."
The user's screenshots show he has bet more than 5.2 million Robux (£52,000) on the site.
Roblox is being sued over the websites
Roblox is now fighting a class action lawsuit in the US by the parents of five children who used these casinos.
The lawsuit, originally filed in August 2023, was given permission to proceed in September 2024 after a judge ruled that Roblox had to answer the parents' accusations of negligence.
"They knew for years it was happening, and they didn't do anything," says James Bilsborrow, the lawyer leading the case against Roblox.
"Roblox has created a digital playground for children - that's the purpose of their platform," he says. "They have a duty to these kids, a duty to keep them safe."
Court filings show that Roblox has been aware of BloxFlip and RBLXWild since at least April 2022, when it contacted their hosting providers asking that the sites be shut down.
It was only in October 2024, however, that Roblox initiated legal proceedings against the websites - accusing them of copyright infringement and breaking its terms of use.
Roblox denies all wrongdoing and says it "employs multiple methods to detect and disrupt bot accounts" connected with the gambling websites.
The parents suing Roblox are also taking legal action against the gambling websites, but so far none of the websites' owners have responded to the lawsuit.
One of BloxFlip's owners told the website's users on their chatroom that "many companies get sued" and that it is "part of doing business".
Taking the websites down
The Bloxmoon website only went offline on 26 November, after Sky News alerted the Gambling Commission which then sent its own takedown request to the website's hosting provider.
Dozens of users flooded Bloxmoon's official chatroom, with one asking if the site had been "taken down by the federal government".
Within 36 hours, however, the website re-emerged at a slightly different web address. RBLXWild was later also taken down only to re-appear at another new address.
The websites continued to receive thousands of dollars worth of bets until 2 December, when users again began complaining that the site was blocked in certain countries, including the UK.
One of the website's staff told users in the official chatroom that they could get around the block by using free software that masks a computer's location.
"If you are unable to access the website please use [the software], certain regions could be blocked at this time," one of the website's staff said in the official chatroom. "We are handling the situation."
Sir Iain Duncan Smith, who leads a parliamentary group on gambling-related harms, says that the casinos will continue to pose a risk as long as the owners are able to escape accountability.
"What you have to do is take them out of the game, so they can't just move domains," says Sir Iain. "There needs to be greater powers to seek these people out, arrest them and put them inside."
Chief executive of the Gambling Commission, Andrew Rhodes, says the regulator is working to identify the casinos' real owners.
"At the end of the day, illegal casino operators are criminals," he says.
"They're supported by criminal gangs and are part of the criminal underworld. It's important all of us play our part in trying to frustrate them."
That includes parents, who Mr Rhodes says need to be "vigilant" to what their children are doing online. But platforms like Roblox also need to safeguard the people using their services, he added.
"They have to remember that criminals are always trying to find ways to exploit children and others and be alive to that risk."
'The adrenaline kept him going'
Robert says he quit after realising that gambling had become an obsession.
"I just wasn't getting the same feeling when I did other things, compared to when I was gambling at home on a Roblox casino," he says.
He now regrets getting his friends involved, especially one for whom gambling is against their religion.
"He knew he shouldn't be doing it, but the adrenaline kept [him] going," Robert remembers. "Then he lost it all in one night, unfortunately."
While he's done with Roblox gambling for good, he does see himself gambling at a legal casino in the future.
Would he have said that if he'd never gambled with Robux?
He pauses to think. "Probably not."
