[Fishing]

A:It’s almost lunchtime, no fish yet.

B:You should say the magic words.

A: Right, I forgot! Fish, fish, send me a fish!.. Hey, I got one! It [color=red]works!

Can I use "It worked " here?

Thanks.

Can I use "It worked " here? – Yes, and ‘worked’ sounds more natural to me.

Maybe “it works” means “It’s really a useful trick” and “it worked” means "it did help’ ?

They have the same meaning but different times.
