'Ready Player Two' author Ernest Cline is going on a book tour inside 'Roblox,' complete with a treasure hunt to win virtual fan gear.

Just as Ready Player One began with a scavenger hunt, so does Ready Player Two--but this time it's in Roblox, and you get to participate.

In honor of Ready Player Two, Roblox is launching a themed treasure hunt with seven user-generated games inside the Roblox platform.
