At every level in the game Rescue Machine, a poor guy is impatiently waiting for you, crushed by a huge stone. He feels very bad, he begs for help. But the stone is so large that it is impossible to move it; a special mechanism is required and it exists, but in a semi-disassembled state. It is necessary to attach something to something, insert it. Add gears and so on. As a result, the machine will start working and pull the rope behind it, to which the boulder is attached and it will rise, freeing the one who was under it in the Rescue Machine.
