Lighthouses are structures that point the way to stray travelers. They were built around the world in the most dangerous places and today in the game Iceberg we will go to the north where on the seashore there is such a lighthouse. But the trouble is, he is exposed to dangers when icebergs approach him. To prevent them from destroying the building, we will have to solve a certain puzzle. In the iceberg will be visible holes of different geometric shapes. Over them will be located pieces of ice, also having a certain shape. You need to insert the necessary pieces into exactly the same holes in the ice. In doing so, you must take into account the trajectory of the sliding of some objects. Once you do this you will be given points and you will move to the next level.
