Personally, when I get tickled people tickle me on my belly (this is because they know I am ticklish most there!). To tickle a boy, you lift the hem of their shirt up, and softly but fastly move your fingers around their entire belly and sides. This is so ticklish, trust me, youll get a great laugh out of them.

the same way you tickle a girl?

Poking her in the sides, or what works with me is if a guy like squeezes the back of my neck on the sides but that doesn't work for most ppl. Also, taking your fingers and put all the tips together than spread them on her knee cap.
Just make sure that you know the girl first, because you can't just go up to a girl and tickle her that you don't know that would be weird. Just poke her in the side of her body!
find her ticklish spot, everyone has one or more, e.g. her knee, her sides(most common one, its just above the hips) or maybe her neck
