In the first box top left, imagine placing a little pin in the white dot on the top left and attach the other white dot by a string. pretend they're cut-outs. Put your finger on the right white dot and drag it around counter clockwise until it ends up under the black dot. Now put the pin in the white dot that's now under the black dot and drag the top left white dot (that originally was in place from the pin), around again. It can't pass the black line in the center so you always just stop when you hit the black line.
Just repeat this multiple times, black dots are floating hire than the white dots so they go underneath. Think of it like a grappling hook and the white dots have to swing around and not cross the black line.
