How do I delete it?

[Armandy]

I installed 'Brain Genius Deluxe'.

But now I want to delete it, but when I go to Settings -> Applications -> Manage Applications, it does not come up on the list???
Hope your suggestion.

You might try to uninstall that app on the Google Play Store app, Menu, My Apps ...

Maybe it's already uninstalled, just that your home launcher stills shows the icon. Try rebooting your phone and check again.
