Combining Match-3 tools increases their effect and lets you clear the field more efficiently!
If you see tools located on adjacent tiles, simply drag one onto another. Сombined, they function as follows:
Combining Dynamite with another Dynamite doubles the radius of the dynamite explosion.
Combining Dynamite with Rocket removes three rows and three columns of pieces coherently.
Two Rockets combined remove one row and one column of tiles.
Combining Dynamite or Rocket with a Fireworks makes the Fireworks take the Dynamite or Rocket to a tile with a level goal on it.
Two Fireworks combined produce three Fireworks that target the level goals.
Rainbow Ball combined with Rocket, Dynamite or Fireworks turn all the pieces of one type (ones that are majority on the field) into respective tools.
Two Rainbow Balls combined remove all pieces from the field, weakening the obstacles that require several steps to be destoryed.
