Level 424 is the fourteenth level in Soda Swamp and the 126th candy order level. To pass this level, you must collect 36 bubblegum pop layers and 6 yellow candies in 17 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The yellow candies on the board are thankfully striped. Due to game mechanics, chocolate squares will thankfully not cover them after each move (causing the player to lose the necessary order) unless no more other possible squares are present.
