In an unknown place, children are trapped in the dark. Their abductor is dead, and you need to find the hiding place and save the children before it is too late. "The Secret of the Mark" is the second part of the Maria trilogy.
50 Clues is an immersive puzzle game that offers the experience of an escape room, but in a format that can be played at home.

The story only makes sense to experience once, but the serial number can be activated 30 times.
