Meteorites are moving to your base located on the Moon. You in the game Cannon Numbers will need to protect your base from destruction. To do this, you will use a special gun that is installed on the surface of the planet. Stone blocks of various sizes will fall on you from above. In each block you will see an inscribed number. It means the number of hits that will need to be made on the meteorite in order to completely destroy it. Quickly orienting and choosing a target, you will aim your cannon at it and open fire. By shooting accurately, you will break the meteorite into small pieces and get points for it. Remember that more than one meteorite should not touch the surface of the planet. If this happens, you will lose the round.
