Rebuild the Iceberg. Physics and logic.
Using physics and logic, it determines the order in which the blocks that have separated from the main iceberg are defrosted. If you thaw them in the correct order, the iceberg will be completed. By clicking on each part of the iceberg, it will fall by the force of gravity, and interact with the rest of the iceberg according to Newton's forces and laws. Think about which iceberg to thaw first.
