This is tip 2 of 4 for Candy Crush Soda Saga 15.
Level 15 Cheat #2: Keep in mind the physics of the board..
Candy Crush Soda Saga has entirely different physics than Candy Crush Saga, and this is one of the most important things to keep in mind when playing. Remember that all the candies below the soda line will float up and fill in from the bottom of the board, and all candies above the soda line will fill in from the top of the board and fall normally. With this in mind, adjust your moves accordingly so you can make the best matches possible.
