A booster for the Cubes puzzle. A Firework removes all cubes and damages objects on one line horizontally (horizontal Firework) or vertically (vertical Firework). The arrows on both sides of a Firework indicate the direction in which cubes will be removed. The type of a Firework (horizontal or vertical) is determined randomly, but the direction changes after each move the player makes.
To get a Firework, you must press on a group of 5 or 6 identical cubes.
