Explosions are not necessarily a sign of a terrorist attack or military action. The explosion is often used in various peaceful works, in particular in the demolition of buildings for the construction of new facilities. As a rule, such explosions should be directed to Blow Off. That is, those who planted the explosives must assume in advance what will happen, where the fragments will fall. If this happens in an area where there are houses, this is especially important. The house should sink without collapsing onto neighboring buildings. In the case of Blow Off, you have different tasks. You need to do this. So that the blocks scatter as far as possible from the white area. Ideally everyone gets to the red mark. You only have one try and one bomb.
