Exemplary implementations may facilitate effectuating modifications within an instance of a virtual space presented via multiple disparate client computing platforms responsive to detection of a token associated with a single client computing platform. In some implementations, tokens may be detected based on signals received from token readers associated with individual ones of the multiple client computing platforms. A given token may be a standalone physical object. The given token may be detectable based on a signal conveying information associated with the given token. The information associated with the given token conveyed by the signal may be devoid of virtual space content.
