25 levels are waiting for you. If the first levels are easy to pass, you may encounter slight difficulties starting with level 5.
Remember, you can restart the level at any time. Adjust the boards so that using the laws of gravity, the cheese will roll down-hill and fall into the mouse's mouth. Apply each nail in the right place so that the wooden bars allow the round cheese to roll to the right place.
You will discover many surprises along the way so don't wait any longer and let the fun... roll!
