Playtika Holding said on Thursday it offered to buy Finnish game maker Rovio, best known for its “Angry Birds” franchise, for 683 million euros ($683 million) in a sweetened all-cash deal.

The offer price of 9.08 euros per share represents a premium of about 60% to Rovio’s close of trading on Jan. 19.

Playtika’s offer is roughly 40 million euros more than its previous offer in November. Shares of Playtika were down 4.7%.

The latest offer comes as the gaming industry is going through a round of consolidation. Last year, Microsoft offered to buy Activision Blizzard for $69 billion, while Sony Interactive Entertainment said it would acquire Bungie Inc, the original creator of the “Halo” videogame, in a deal valued at $3.6 billion.
