"Guess who I met today?"

"Hmm... I_____(give up, gave up)."

Thanks.

I give up.
(present tense to refer to the action of giving up guessing right at that moment.)

Compare with:
She asked me to guess who she met, but after three attempts I gave up.

What about if you are asked to find something, but after looking all over the place for it, you still can't find it. Then which one is used, I give up or I gave up?

By the way, you are asked to find something or you are asked to look for something?

[Beeesneees]

The same applies - it depends on when it happens.
I've looked everywhere but can't find it so I give up. can't - present
I looked everywhere but couldn't find it so I gave up. couldn't - past

'Find' or 'look for' both work.

By the way, what is the bridge like thing that helps you cross over a busy street? And bridge-like or bridge like?

[Beeesneees]

If I am right about what you are thinking, in the UK the 'bridge-like thing' would be a footbridge.
