Opposite of obvious?

What's the opposite of obvious other than 'not obvious? It's ... not obvious to me

 

oblique, ambiguous (sp??), indirect, vague, inconcievable (sp??) Please excuse spellings lol

 

Discreet?

If you check thesaurus.com, it should have an antonym section.

obscure, cloaked, unseen, unknown, vague, murky... as Cogito said, it greatly depends on the context.
