YANIV DE RIDDER, et al., Case No. 23-cv-04146-VC

Plaintiffs, ORDER DENYING DEFENDANT v. SAID’S MOTION TO DISMISS PLAINTIFFS’ UCL AND COMMON ROBLOX CORPORATION, et al., LAW CLAIMS Defendants. Re: Dkt. No. 246

The California Penal Code contains several provisions that prohibit operating a game of chance in which the player can win or lose a “thing of value.” These provisions were drafted a long time ago, and they are very difficult to understand. The question presented here is whether a website that enables people to gamble away their Robux—the virtual currency that kids spend to play games on the Roblox platform—is operating games of chance in which players can win or lose a thing of value. The answer is yes. Although the meaning of “thing of value” under the relevant provisions is more difficult to discern than it should be, Robux must be considered things of value because they are akin to arcade tokens. Roblox users spend money to purchase Robux, which, like tokens, can be used to acquire a desired product: gameplay. If you’re playing a game in an arcade and someone reaches into your pocket and steals your tokens, they have stolen something of value. Similarly, if someone steals your Robux, they have stolen something of value. A website that entices children to gamble away their Robux on games of chance is therefore enticing them to part with something of value. Because Robux are “things of value” under any reasonable understanding of that phrase, it does not matter for purposes of this case that the language and structure of the California Penal Code make it nearly impossible to figure out a definition of “thing of value.” But this case shines a light on the need to clean up these old gambling provisions to be clearer about what they cover, especially as online games played for various forms of virtual tokens and currencies become increasingly common. Indeed, as discussed below, there is a serious possibility that the Penal Code provisions at issue here would be unconstitutionally vague as applied to a different defendant. I The following facts, taken from the plaintiffs’ complaint, are accepted as true for purposes of this motion to dismiss. Roblox is an online gaming platform that is used primarily by children. The games on the platform are user-generated, meaning that they are created by third-party developers. The Roblox platform is free to use, but users pay to play games using “Robux,” the platform’s digital currency. Roblox users can buy Robux in various quantities on the Roblox website. For example, a user can get 400 Robux for $4.99 or 800 Robux for $9.99. This is one of the ways Roblox makes money from its platform. And game developers can make money by charging users Robux to play their games and purchase in-game items. Game developers who participate in Roblox’s Developer Exchange Program can cash out their Robux in exchange for real money (although Roblox takes a cut). The Developer Exchange Program is the only way to exchange Robux for cash on the Roblox platform. Boris Said, Jr., is the creator of the now-defunct RBLXWild.com. RBLXWild was a third-party website outside the Roblox platform that hosted gambling games, such as coin flips, blackjack, and plinko. As the name suggests, RBLXWild targeted Roblox users. Roblox users could link their Roblox accounts to the RBLXWild website to spend their Robux on RBLXWild’s games. And because RBLXWild participated in Roblox’s Developer Exchange Program, it could exchange its Robux for cash. RBLXWild made up to “five figures a day” in revenue before it shut down in response to the filing of this lawsuit. The plaintiffs are children who gambled away their Robux on RBLXWild. They filed this proposed class action lawsuit in August 2023 against Roblox and later added Said as a defendant (along with two other defendants who allegedly ran other Robux gambling websites). The plaintiffs assert statutory claims based on the California Unfair Competition Law as well as common law negligence and unjust enrichment claims. Said has moved to dismiss the claims against him. He argues, in part, that his conduct was not unlawful and therefore cannot support the plaintiffs’ claims against him under the “unlawful” and “unfair” prongs of the UCL. And he argues that the plaintiffs’ negligence and unjust enrichment claims against him should be dismissed for the same reason. This ruling addresses those arguments. The other arguments raised in Said’s motion to dismiss will be addressed in a separate, unpublished ruling. II California’s Unfair Competition Law prohibits “any unlawful, unfair, or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. A business practice is “unlawful” under the UCL if it violates another state or federal law. Cel-Tech Communications, Inc. v. Los Angeles Cellular Telephone Co., 20 Cal. 4th 163, 180 (1999). That means that any violation of the UCL’s “unlawful” prong must be predicated on some other legal violation. The plaintiffs allege that Said’s conduct—providing gambling games on RBLXWild— violated four provisions in the California Penal Code. The first three, Penal Code Sections 330a, 330b, and 330.1, prohibit operating slot machines and other gambling devices. A game is considered a slot machine or gambling device under those statutes if it allows users to win or lose a “thing of value.” The fourth provision, Section 337j, prohibits operating a “controlled game” without the required licenses. A “controlled game” includes (with several exceptions not relevant here) any “game of chance” that is played for a “thing of value.”1
