Candy Crush Saga is a free-to-play tile-matching video game released by King on April 12, 2012, originally for Facebook; other versions for iOS, Android, Windows Phone, and Windows 10 followed. It is a variation of their browser game Candy Crush. In the game, players complete levels by swapping colored pieces of candy on a game board to make a match of three or more of the same color, eliminating those candies from the board and replacing them with new ones, which could potentially create further matches.
