Mobile gaming is bigger than its ever been these days, but there are gamers out there who still have a tough time with on-screen controls due to their fingers being too large or relying on the feel of a dedicated gaming controller all their lives. Nyko introduced its PlayPad controller back at E3 and it's launching across GameStop retailers starting today.

Nyko's PlayPad can be purchased through its website, but the PlayPad Pro can only be purchased at GameStop at this time, although it will be available on Amazon starting on Feb 1, 2013. Both the PlayPad and PlayPad Pro are available for $39.99.

Both controllers are compatible with Android and iOS devices, which is something that isn't typical these days in a mobile controller as they usually support one or the other. If you're in the market for a dedicated controller for your mobile games, you might want to check out Nyko's PlayPad.
