Candy Crush Saga is a free-to-play match-three puzzle video game released by King on April 12, 2012, for Facebook. 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.
If you’ve never heard of this app, I'll tell you that Candy Crush is one of the best free games that you can play, even without internet access, on your mobile or PC. It was released to the public for the first time in April 2012 and since then it has maintained its popularity among users like myself.
Its core gameplay is that it is a "match-three game", meaning that the goal is to swap three adjacent candies "among several on the game board as to make a row or column of at least 3 matching-colored candies."
There are actually three different versions of this amazing game, and each one has a different number of levels.
