Robux gambling ruling: why affiliates are exposed

A federal judge ruled, at the pleading stage, that Robux are a thing of value under California gambling law. What Colvin v. Roblox decided so far and what it means for traffic sources.

In December 2025 a federal judge in California refused to dismiss Robux gambling claims against the owner of RBLXWild, ruling at the pleading stage that Robux are a "thing of value" under the state's Penal Code. Roblox, accused of taking a 30% cut of cashed-out Robux, has not been found liable. No final judgment was reported by October 2026.

Context: how Robux gambling sites work

Players pay real money for Robux and spend it on items and access inside Roblox, a platform whose users are largely young. What they cannot do is turn store-bought Robux back into cash. Cash-out runs only through the Developer Exchange (DevEx) programme, which, according to Roblox's own documentation, pays eligible creators a standard $0.0038 per earned Robux, with a 30,000 Robux minimum.

Roblox bans playable gambling in games, simulated gambling included, and lets a casino appear only as a backdrop players cannot bet on. This case is about something else: separate websites that accepted Robux as stakes.

Robux gambling sites like these sat off the platform. Roblox told Bloomberg Law in 2023 that they had "no legal affiliation" with it and that "bad actors" were using its intellectual property and branding to run them in breach of its standards.

For the wider picture of which forms of online betting US states permit, see our guide to whether online gambling is legal in the US.

What they did

According to the complaint as summarised by Bloomberg Law, a player bought Robux on Roblox, went to a defendant's site and linked a Robux wallet to it there. Bets were then taken in Robux. On RBLXWild, Casino.org reported, the menu included coin flips, blackjack and plinko. Players could win only more Robux, not money.

That limit was the core of the owner's defence. The site itself, though, was enrolled in DevEx and could exchange Robux for cash, Casino.org reported. Robux gambling games of this kind work like crash games and other instant formats: one stake, one result in seconds, then the next round.

California's Penal Code, as Casino.org summarised it, treats an unlicensed "controlled game" of chance played for "any thing of value" as illegal gambling. The plaintiffs allege that the sites ran exactly that kind of illegal gambling. For what a licence changes for an operator and its partners, see our overview of online gambling licenses.

The plaintiffs allege that Roblox takes a 30% fee when the sites convert Robux back into dollars, and earns "millions in annual cash fees" from it (Bloomberg Law). Roblox says the sites are not affiliated with it.

Promotion followed the audience. The complaint alleges that Bloxflip gave free Robux to users who promoted it on TikTok. One industry write-up puts creator and affiliate payouts in this niche at roughly 10 to 20% of referred deposits. We could not verify the range against any published programme terms.

Results

Two California parents filed the proposed class action in the Northern District of California in August 2023. They sued Roblox and the companies behind RBXFlip, Bloxflip and RBLXWild after their children lost Robux on the sites. Besides illegal gambling, the claims include negligence, unjust enrichment and unlawful practices under California's Unfair Competition Law.

September 2024: the platform. In a seven-page order, Judge Chhabria again allowed negligence claims against Roblox to proceed. He said Roblox had acted with misfeasance and owed its users a duty of protection, Courthouse News reported. That order did not find Roblox liable. It only kept the claims alive.

December 2025: the site owner. RBLXWild's owner, who had closed the site after the suit was filed, moved to dismiss. His argument: Robux are virtual items players cannot redeem for cash, so betting them is not gambling. The judge disagreed. In Casino.org's account, he reasoned that a site able to convert Robux to cash could hardly be said to run a game without a thing of value. He also flagged the vague wording of the statute, writing that "criminal liability hinges on the meaning of this ill-defined phrase". Separately, MLex reported, the judge found the allegations enough to make it plausible that RBLXWild was a "sham corporation" used to avoid personal liability.

The December ruling does not decide whether anyone is liable. It decides only that the claims against the owner can go forward.

We could not open the court orders themselves. Holdings above are as reported by the outlets listed in Sources, and this case file does not cover other orders on Roblox's motions.

Outside the US. In December 2024 the UK Gambling Commission warned that illegal casinos were exploiting minors through Roblox, Gambling Insider reported, and Action Network reported that offshore casinos targeting children on Roblox had suspended operations indefinitely. We could not reopen either report for this update. On 30 January 2026 the Dutch regulator ACM opened a Digital Services Act investigation into how Roblox protects minors, expected to take about a year. That probe covers child safety in general, not gambling alone.

What did not work

The owner's main defence failed at the first stage. Calling Robux play money did not hold once the court focused on the site's own ability to cash them out. The corporate structure also failed as a shield, at least on the pleadings.

The picture is still open in several ways:

  • Motion stage only. The December 2025 ruling assumes the complaint's allegations are true. It is not a verdict, and no damages have been set.

  • One court, one state law. The ruling applies California law in one federal case. Other states define gambling and "thing of value" in their own words.

  • Minors. The plaintiffs say children reached the sites unchecked. Anyone sending that traffic carries the reputational risk whatever the court decides.

  • Gatekeepers. Ad platforms, app stores and payment processors generally refuse unlicensed gambling aimed at minors, with or without a court order.

Takeaways for affiliates

  • Treat virtual currency as money. If a currency can be turned into cash anywhere along the chain, assume, for risk planning, that the product is real-money gambling, and set partner terms and compliance checks to match.

  • Owners were exposed; promoters were not parties. The case says nothing about affiliate liability, but at the first stage a court let claims proceed against a site owner personally and doubted his shell-company defence.

  • Audience age is a deal-breaker. Traffic built on game creators and social video skews young, as the complaint alleges. If you cannot show your audience is adult, do not run gambling offers to it.

  • Check the licence behind every game. If a site you are offered lists slot titles from licensed game studios, that does not license the site. Ask which regulator covers the operator itself.

  • Watch platform terms, not only courts. Roblox calls these sites unauthorised users of its brand, and platform action can cut a traffic source faster than a lawsuit.

  • Learn from other grey zones. The sweepstakes casino bans show how fast affiliate income disappears once regulators act.

FAQ

Is gambling with Robux illegal in the US?

There is no nationwide answer. In one federal case, a judge in California ruled in December 2025 that Robux count as a "thing of value" under the California Penal Code and let illegal gambling claims against a site owner proceed. The ruling applies California law at the pleading stage.

Is buying Robux gambling?

The case does not challenge buying Robux. It concerns betting Robux on third-party sites. Roblox's own rules separately ban playable gambling inside games.

Was Roblox found liable for Robux gambling sites?

No. As of October 2026 no final judgment had been reported. In September 2024 the judge let negligence claims against Roblox proceed, which keeps the claims alive but is not a finding of liability.

Can affiliates be held liable for promoting Robux gambling sites?

Affiliate liability was not decided in Colvin v. Roblox, because no affiliates or creators were defendants. Ad bans, platform enforcement and minors in the audience are the more immediate risks. This is not legal advice.
