Cheating tip; use two hands, place your finger on both of the sliders, then almost complete the first one, then finish the second one.

Works fine until you get to the crossing patterns. :)

Is there way to solve the puzzles without doing that?!

I don't think so. Some of the 3 or 4 puzzles require rotation and cris crossing

Is that cheating? Seems difficult enough for me, still.
