The mechanics only allow the elimination of the targeted 3x/4x/5x fruits, unlike the case of Candy Crush in which more number of fruits in more position can be eliminatedTherefore, while the board is constantly changing for Candy in a large extend, the board here, especially the lower part , is stable.Hence players can only rely on luck to make matches on the lower part if the lower part does not have matches to begin with.The Flower Goal requires players to match in certain positions; that is why people are frustrated in stages where a Flower sit in the lower board.
