Can The iPhone 4 still run alot of games?

I plan on buying my mates iPhone off him soon as he is upgrading to a 5 and is selling his iphone 4 to me for £20. I already have a samsung phone so I don't intend to replace the iphone with my existing phone instead I just wish to play the ios exclusive games and put a bit of music on the phone. However I know the iPhone 4 is quite a old bit of kit now with all the newer models out so my question is will I be able to run the majority of the games on the iPhone? Or is it too outdated and i'll only be able to run the lower spec games

Added (1). Does it have gyroscope aswell? As I hear alot of games use that now

I have an iphone 4s it plays anything i throw at it

The iPhone 4 is actually capable of running pretty much all of the apps on the app store. Because it is the 4th gen, it will most likely be IOS 7 or lower, which is perfectly fine. So the answer to your question is yes, lots of games providing there's enough available memory/storage left on there.

Yeah its fine but you may need to update it to iOS 7 as most apps today are made for iOS 7
