How many Cypher parts are there BTS?

Which is the best Cypher BTS?
But the best Cypher is hands down Cypher Pt. 3: Killer. That song saved my life. It includes some of the most iconic lines: "all them unnies call me beep beep" and Yoongi's entire verse about taking men and women to Hong Kong (lol) with his rap skills.Dec 28, 2018
What is the meaning behind BTS Cypher?
In total, there are now four. Let's first define what Cypher means. In hip-hop, cypher is a freestyle circle. But, as we see with “Outro: Circle Room Cypher,” BTS' “Cyphers” aren't freestyle tracks. In their case, Cyphers are just circles, referring to the practice of taking turns one after the other.Sep 13, 2020
