The Four-of-a-kind Special Match creates a burst
of flame that shoots out from both ends of the match. This can be counter
intuitive for Candy Crush veterans since it is essentially opposite the way
Striped Candies work. The flame will damage obstacles, but also has the
interesting effect of destroying level 1 peppers, while concentrating higher
level ones.

Warning – Be careful when using the Four-of-a-kind Special
Match, as it can easily scramble other matches you had lined up. It is also
best to use when you have higher level peppers lined up, since the level 1
peppers are destroyed and get no benefit from the flame.
