Edible and inedible objects fall from top to bottom. The edible ones need to be cut before they reach the bottom. Otherwise, they will turn into bricks. Inedible items should not be touched. If the bricks reach all the way to the top, the level is considered lost.
To cut an edible object, click on it, or touch the object with your finger on a mobile device. Inedible items should not be touched.
