Matching 3 or 4 or 5 candies in a row earns a special wrapped candy that can clear a whole row.
Match 4 candies in a row to earn a striped candy. The striped candy, once matched with a color, removes every candy of that line.
Match 5 candies in a row to earn a bomb. The bomb, once matched with a color, removes every candy of that color from the board. Make sure to match it with the most prevalent color.
Combine bomb with striped candies to get multi-striped.
