Question: are the skylanders portals universal?
Answer: The Spyro's Adventure 3DS portal is universal and will work on any system with that game except an Xbox 360; the Spyro's Adventure portals of other consoles can also work with the PC version of Spyro's Adventure. The PS3, PS4, Wii and Wii U have the same portal and are interchangeable in any of the games.
