The Coin Master lawsuit that most people are searching for is Williams v. Moon Active Ltd., a 2025 federal class action in the Northern District of California alleging that the game’s spin mechanic is illegal gambling marketed to children. On December 9, 2025, the court sent the case to arbitration and stayed the proceedings, which blocks the class action from moving forward for now. No class has been certified, no court has ruled on the gambling claims, and no settlement has been announced. An earlier New York case raising similar claims was voluntarily dismissed in 2022.
What the 2025 Class Action Claims
Renika Williams filed the complaint on February 14, 2025, on behalf of herself and D.K., a minor she represents as next friend.1Top Class Actions.

The complaint targets the game’s slot machine mechanic. Players spin a virtual wheel to earn coins, attack other players’ villages, or raid them for resources. Free spins run out, and the suit alleges the game is designed to push players into buying more spins with real money. D.K., according to the complaint, used gift cards and a credit card to buy thousands of virtual coins and spins.3Findlaw. Williams v Moon Active Ltd
The plaintiffs argue that staking real money on random outcomes the player cannot control meets the legal definition of gambling under California law.1Top Class Actions. Class Action Says Kid-Friendly Coin Master Game Involves Illegal Gambling They also allege Moon Active deliberately markets the mechanic to children through cartoonish graphics, a colorful interface, celebrity endorsements, and YouTube promotions, while the terms of service give parents what the complaint calls “misleading” assurances about safety.
The suit brings four claims: violations of California’s Unfair Competition Law, negligence, negligence per se, and unjust enrichment. It seeks money damages, restitution, and a declaratory judgment for a proposed nationwide class and a California subclass of legal guardians whose minor children spent money in the game.1Top Class Actions.

Why the Case Was Sent to Arbitration
Judge Yvonne Gonzalez Rogers granted Moon Active’s motion to compel arbitration on December 9, 2025, and stayed all proceedings.3Findlaw. Williams v Moon Active Ltd The ruling turned on a technical but consequential question: whether a minor could be forced to arbitrate her claims.
When D.K. registered to play, the game showed a pop-up requiring her to confirm she was at least 18 and had read the terms of service. Those terms included an arbitration clause and a class action waiver. The court found this gave “conspicuous notice” of the arbitration requirement.3Findlaw. Williams v Moon Active Ltd
The plaintiffs tried to escape arbitration by pointing to letters D.K. sent in June and July 2025 disaffirming “all contracts” with Moon Active. Under California law, minors generally have the right to void contracts they enter into. But the terms of service contained a delegation clause saying any dispute over “the enforceability, validity, scope or severability” of the arbitration agreement itself had to be decided by an arbitrator rather than a judge.
Judge Rogers ruled that because D.K.’s disaffirmance letters targeted the terms “as a whole” rather than the delegation clause specifically, the question of whether the disaffirmance was valid belonged to an arbitrator. The court relied on the Ninth Circuit’s reasoning in Three Valleys Municipal Water District v. E.F. Hutton, which held that attempts to avoid or rescind a voidable contract fall within the scope of a valid delegation clause.3Findlaw. Williams v Moon Active Ltd
The “All Contracts” Versus “Any Contract” Distinctionh3>
The ruling relied on a narrow distinction from a 2024 California appellate case that came out the other way. In J.R. v. Electronic Arts, a minor successfully escaped arbitration in a dispute over Apex Legends. He had disaffirmed “any contract or agreement” accepted through his EA account, language the Court of Appeal found specific enough to reach the delegation clause and put the issue in front of a judge.4Findlaw. J.R. v Electronic Arts Inc
Judge Rogers distinguished Coin Master by pointing to the wording: D.K. disaffirmed “all contracts,” while J.R. disaffirmed “any contract or agreement.” The court treated the difference as meaningful, holding that a minor who wants a judge to decide the validity of a delegation clause has to specifically target that provision instead of making a blanket disaffirmance.3Findlaw. Williams v Moon Active Ltd
Where the Case Stands Now
The Williams case is administratively closed and stayed pending the outcome of arbitration.3Findlaw. Williams v Moon Active Ltd The public record does not show that an appeal has been filed or that individual arbitration demands have been submitted. The court ordered the parties to file a joint status report within 14 days of the arbitrator’s final decision, at which point either side can move to reopen the case if necessary.
For anyone hoping to join a class, the practical effect is significant. Arbitration is individual by nature, and the terms of service include a class action waiver. Unless the arbitrator or a later court reverses course, the claims are unlikely to proceed as a class action. Any parent whose child spent money in the game would generally need to pursue their own arbitration rather than wait for a group recovery.
The Earlier New York Lawsuit
Williams was not the first gambling suit against Coin Master. On March 7, 2021, Marcus Fryar filed a class action in the U.S. District Court for the Southern District of New York on behalf of New York residents who paid to play the game.5Classaction.org. Fryar v Moon Active Ltd Complaint
The Fryar complaint went further than Williams in describing alleged manipulation. It claimed the game goes “beyond randomness” by tilting outcomes in favor of the house, calculating how many spins a player needs to win a prize and rigging results to ensure the player spends the maximum amount possible.6Classaction.org. Coin Master Mobile Casino Game Tilted Too Far in Favor of the House, Class Action Says Players who spent more, the suit alleged, were rewarded with better outcomes like the ability to raid villages with higher coin totals, while non-paying players were penalized. The legal theory relied on New York gambling statutes, treating in-game spins as “something of value” under Penal Law § 225.00 and seeking recovery under General Obligations Law § 5-421, which lets someone who loses $25 or more at gambling sue to recover their losses.5Classaction.org. Fryar v Moon Active Ltd Complaint
Fryar never reached a ruling on the merits. Moon Active moved to compel arbitration or dismiss the complaint, and before the court decided that motion, the plaintiffs voluntarily dismissed the case on March 28, 2022. The motion to compel was denied as moot.7CourtListener. Fryar v Moon Active Ltd Docket No public reason was given for the dismissal, and no settlement was announced.
How Similar Social Casino Cases Have Ended
The Coin Master lawsuits sit inside a wider wave of litigation over games that mimic casino mechanics but pay out in virtual currency. Those cases matter here because they show what a plaintiff can win when the arbitration barrier does not shut things down.
The Ninth Circuit’s 2018 decision in Kater v. Churchill Downs Inc. held that virtual chips in Big Fish Casino are a “thing of value” under Washington state law, because without chips a player cannot access the game’s features.8GamesIndustry.biz. Big Fish Casino Ruled Illegal in Washington Big Fish’s parent companies later agreed to a $155 million settlement in 2020, along with game changes that let players who run out of chips keep playing without buying more.9GeekWire.

Benson v DoubleDown Interactive LLC
In February 2025, a Tacoma jury returned the first trial verdict in social casino litigation, awarding roughly $25 million against a High 5 Games subsidiary, including about $18 million in direct damages and $7 million in enhanced damages. Trial evidence showed the company used internal designations like “whales” to identify users showing signs of gambling addiction, and that one user who asked to close their account was lured back with free coins.11Edelson PC.

Washington Attorney General Nick Brown also filed a new suit in February 2026 against Playtika and Aristocrat, alleging their social casino apps have taken more than $225 million from Washington residents since September 2020 in violation of state law.13Washington Attorney General. AG’s Office Sues Illegal Gambling Apps That Have Taken More Than $225 Million These outcomes show the underlying gambling theory has traction in some states, but each of those cases stayed in court. Coin Master’s arbitration clause is the reason Williams is currently on a different track, and it explains why the merits of the gambling claim against Moon Active have not yet been decided by any judge or jury.
