I would like to delete some of the games from my I phone.

Hello there, chalkie11.

The following Knowledge Base article offers up some great information on deleting content from you iOS device:

How to delete content you've downloaded from the iTunes Store, App Store, iBooks Store, or Mac App Store

Particularly for Apps:

Apps

iPhone, iPad, or iPod touch

Before you delete, find out if you'll be able to download the app you deleted again (it depends on where you live).

1. Tap and hold an app you want to delete.
2. The apps will begin to jiggle.
3. Tap the "x" on the app you want to delete

Thanks for reaching out to Apple Support Communities.

Cheers,

Pedro.
