Candy crush saga is a "match 3" game based on swapping two adjacent candies on the game board to form rows or columns of at least three candies of the same color. This game is liked by all people in different age categories. It is one of the interesting and relaxing game for all people who liked to play. In this game, matching candies are removed from the board, the candies above them fall into empty spaces, and new candies appear from the top of the board. This creates a new set of matching candies and automatically removes them in the same way. Players score points in these matches, and progressively more points in a chain reaction. Also, creating matches of four or more can cause rows, columns, or other points on the board when matched. A special candy is created that allows you to clear the section of the board.

The game is divided into many levels that must be completed one after another. It is very interested to move to the next level. Each level presents a different challenge to the user. Get the minimum score in a set number of moves, or remove candies in a set number of moves to bring special ingredients to the bottom of the board. Boards come in different configurations and can contain special squares with their own rules, such as: when the player completes the level goal, he gets one to three stars depending on the score and can proceed to the next level. Otherwise you will lose a life and have to try again. If the player runs out of lives, they must wait in the real world for sometime to regenerate their lives before trying the level again. Completed levels can be repeated if desired.

The game has added many episodes, each with dozens of new levels and new game mechanics. Each episodes has 15 levels of game. In the game's first major expansion, the game added another set of levels to the dream world. The levels shared the same objective, but the player had the option of not disturbing the sleeping owl. Now, I had to balance two randomly chosen colored candies. If they failed, the levels had to be repeated. Collecting enough matching candies to fill a meter, the game automatically activated his moonstruck power. All candies of these two colors were removed from the playing field and the player received one.
