L and T shape Special Matches work a lot like Four-of-a-kind, except that they always concentrate on the peppers in the path of their flame, regardless of level. This makes them a lot more powerful, and typically the better choice, unless you are worried about the direction of the flame generated. As with Four-of-a-kind, the flame shoots off the ends of the completed match.

The “T” shape has no advantage over the “L” shape in terms
of fire jets. Sometimes you have the choice of one or the other – choose the
shape that will shoot the jets in the best columns and rows for your
board.
