In a new class action lawsuit filed in the Northern District of California this week, two parents accuse Roblox of illegally facilitating child gambling.

While gambling is not allowed on the platform, which hosts millions of virtual games that cater to children and teens, the lawsuit points to third-party gambling sites that invite users to play blackjack, slots, roulette and other games of chance using Roblox’s in-game currency.

The lawsuit, first reported by Bloomberg Law, was filed on behalf of plaintiffs Rachel Colvin and Danielle Sass, two mothers with children who have gambled on third-party sites that tie into Roblox’s virtual currency, Robux. Both parents claim that their children, named as minor plaintiffs in the suit, have lost thousands of Robux gambling on those sites without their knowledge (Robux currently sells 800 Robux on its website for $9.99 with deeper discounts for larger amounts of the digital currency).The lawsuit specifically names RBXFlip, Bloxflip and RBLXWild as participants in “an illegal gambling operation that is preying on children nationwide.” The owners of those sites are named as defendants along with Roblox itself. RBXFlip, which entices players with “fun and fair games,” has been on the radar of the Roblox community since at least 2019 and continues to operate today.

Roblox itself is a vast collection of virtual experiences and not a game in a traditional sense. Those experiences, crafted by amateur and professional developers alike, can lightly depict gambling by showing casinos or non-player card dealers, for example, but “experiences that include simulated gambling, including playing with virtual chips, simulated betting, or exchanging real money, Robux, or in-experience items of value are not allowed.”

The plaintiffs call those rules misleading, given Roblox’s apparent tolerance for third-party betting sites. “In its Terms of Service, Roblox misleadingly represents to parents and other users that its platform and digital currency are safe,” the lawsuit states. “… This representation is false, or misleading at best.”The lawsuit alleges that Roblox maintains control over the flow of Robux and therefore has full knowledge of shady, third-party gambling sites that entice kids to play with the in-game currency.

“Roblox could, of course, prohibit and/or stop the Gambling Website Defendants from utilizing the Roblox ecosystem and digital currency to facilitate illegal gambling but it does not,” the lawsuit states, accusing the company of profiting from the scheme in the millions by drawing a 30 percent fee on transactions, those included.

In an email to TechCrunch, Roblox declined to answer specific questions, but emphasized that the gambling sites are in no way affiliated with Roblox.

“Bad actors make illegal use of Roblox’s intellectual property and branding to operate such sites in violation of our standards,” the company wrote in a statement.

“… Ensuring a safe and compliant online experience for users of Roblox is a core tenant of the company. Roblox will continue to be vigilant in combating entities who engage in practices that are in violation of our policies or endanger the safety of our community.”
