One of the extremely rare artifacts of the Inside Out.\n\n According to some stalker tales, whoever manages to obtain Rubik will always be lucky on their outings. Those who do not believe in the tale find a simple explanation for this 'luck' — the range of useful properties exhibited by the Rubik is extremely diverse, allowing it to be used in numerous assemblies.\n\n Like some other Inside Out artifacts, it does not have a known direct parent artifact or analogue that could be found in the usual Zone. However, many stalkers, fond of speculating on the popular or selling their genius idea to scientists, claim that the Rubik might be some mixture of the Polyhedron and Atom.
