Kink generates random looped curves for you to trace over. You can start tracing from any portion of the curve. A black spot appears at the opposite portion and starts to follow the curve in the same direction you took. You need to avoid touching this dot or you will get kinked. If traced correctly, a new curve is created with an increased level of difficulty.
