Tens of thousands of class members 'purchased and lost chips' by wagering at DoubleDown Casino, the plaintiffs' lawyers alleged. The lawsuit said consumers wager to acquire more chips that they otherwise would need to buy. The games are free to play, but users pay for additional chips. They argued that the plaintiffs' claims 'rest on novel and untested interpretations of Washington's gambling laws.' International Game Technology, based in the U.K., and DoubleDown have denied any liability.

Online consumers alleged 'social casino' games developed by the defendants 'constitute unlawful gambling under Washington's gambling laws.' The settlement was the latest in a series of related cases.
