The case, which was filed on Tuesday in California Superior Court, by investors Sean Debotte and Michael Nunes accused King Digital of misleading investors in its federal documents, Mashable reported.

The suit said that the company claimed that 97 million active users played 1.065 billion average daily games of Candy Crush ahead of the company's initial public offering a year ago.

However, that figure had witnessed a "significant decline" as once-paying customers began to leave the game. The suit argued that the company should have revealed the real numbers at the time of the IPO.

According to the company's official IPO filings, Candy Crush Saga accounts for nearly 80% of King's business. The firm sold shares worth $499.5 million to the public last year at $22.50 per share. King executives earned millions, as did their financial backers, the lawsuit said.
