(Reuters) -Match Group was sued on Wednesday in a proposed class action claiming that its dating apps Tinder, Hinge and The League are designed to addict users, generating more profit for the company, rather than help them establish relationships.

The plaintiffs said Match's "predatory" business model defrauds those looking for love and fearful of missing out with an algorithm that rewards "compulsive use" of its platforms, and entices them to pay hundreds of dollars a year for subscriptions.

Match employs features "to gamify the platforms to transform users into gamblers locked in a search for psychological rewards that Match makes elusive on purpose," according to the complaint filed in federal court in San Francisco.

The six plaintiffs - who live in California, Florida, Georgia and New York - called this inconsistent with Match's ad slogan that its apps are "designed to be deleted."

In a statement, Match rejected the plaintiffs' claims.

"This lawsuit is ridiculous and has zero merit," Match said. "Our business model is not based on advertising or engagement metrics. We actively strive to get people on dates every day and off our apps. Anyone who states anything else doesn't understand the purpose and mission of our entire industry." Match Chief Executive Bernard Kim told analysts on Jan. 31 that the Dallas-based company adopted a "fast-fail mentality" to move on from features that don't work, and that Tinder and Hinge are using artificial intelligence to improve users' experiences.
