Candy Crush Saga

Candy Crush Saga is a match-three puzzle mobile game developed by Sweden's King and launched in 2012. Players swap adjacent coloured candies on a grid to match rows or columns of three or more, triggering cascades and special candies. Its 'saga map' progression, live-play mechanics and monetisation model made it the archetypal mobile free-to-play blockbuster, with billions of downloads and Activision Blizzard acquiring King for US$5.9 billion in 2015.
