Each rubber rope wants to reach out and connect with its own button in Color Rope Matching, and their colors must match. The rule seems to be simple. But in order to fulfill it, you must learn one exception - in no case should ropes of different colors intersect. If this happens, they will turn black and you will understand that you are doing something wrong. To stretch all the ropes on the field and fulfill all the conditions, you need to use sere nails. You can hook onto them and go around a dangerous area, preventing them from approaching other ropes in Color Rope Matching.
