1. First, we need to go to Tik Tok's message page and open the chat dialog bar with friends.
2. Then click to enter the bar of friends' chat session, and then click to open the icon of continuous chat below.
Finally, we can see the Spark Rules page in the chat page with friends. If we chat for more than three days and send pictures or video messages to each other, we can get purple sparks and set them up for use.
Tik Tok is a popular short video software, among which Spark logo with dating function is a favorite game of many users. Tik Tok sparks include gray, red, purple and so on. When two people chat for more than three days, they will get the logo. The longer the interaction, the deeper the color of the spark logo. However, once there is no interaction between the two sides for more than one day, the Spark logo will disappear immediately.
