#1 on all possible Korean Music Charts:
- MelOn, Genie, MNet, Bugs, Soribada,Olleh, Daum, Naver, Monkey, (+ Cyworld for non-SM acts)
- I purposely ordered the bolded charts by relevance. Those are the Top 5 charts.
- Basically, MelOn is overwhelmingly the #1 chart (EDIT: updated with 2014 information); no one (*coughAKPcough*) should be creating all-kill scenarios that don't include it.
Certified All-Kill (Instiz ONLY)
- #1 on all Realtime Charts
- #1 on all Daily Charts

Perfect All-Kill (Instiz ONLY)
AKA all #1 everything:
- #1 on all realtime charts
- #1 on all daily charts
- #1 on Instiz Weekly Chart
- When I say all, I mean the above list + Cyworld
An Instiz PAK is very difficult to get. Right off the bat, SM artists will never get one because of the Cyworld issue. I think IU may have been the last artist who has pulled it off. Recently, SISTAR got really close with "Touch My Body"--in fact Instiz accidentally tweeted that they got it, but took it back; I think they were missing Cyworld daily or realtime at the time.
picture of IU's latest PAK:
- MelOn has their own Perfect All-Kill (that they gave to Winner's Empty). (EDIT: people in the Winner PAK thread seem to agree that the criteria is #1 realtime, #1 daily, #1 weekly and #1 album)
- I've heard people use "all-kill" to refer to the phenomenon of all n tracks on an album taking the top n spots in a single chart. (For example, if the mini-album has 5 songs, then it's when those songs are #1, #2, #3, #4 and #5). AFAIK that's not official, but I get why people would want to consider it an achievement.
- And of course there is the "Real-time All-Kill" when a song gets #1 on all the realtime (hourly) charts
Rooftop Hit/"Hitting the Roof"
Not merely hitting #1, but being an extremely dominant #1. It used to be much easier to hit the roof multiple times on MelOn before they changed their formula. I think the current record holder for # of rooftop hits is MC Mong's "Did You Miss Me" with 16 roof hits.
Why milestones on the 5-minute chart shouldn't count
Oh look, Superjunior Mamacita was #2 on MelOn at 5:05 AM:
Wait a second, it's 5:10, where did Mamacita go? Did I hallucinate the previous 5 minutes? (And I mean that literally because I was the one who took these screenshots)
Their eventual rank that hour? Nowhere near the Top 10 not even to talk about the Top 3.
A similar, less dramatic, example was Infinite's Back. It'd hit #1 early on in the hour on MelOn's 5 minute chart, but when the hourly update came, it'd be somewhere between #3 and #5.
If you really want to count 5-minute chart #1s, I can't stop you, but my personal opinion is that the 5 minute chart is too volatile to mean much.
Let me know if I got anything wrong, or if I'm missing something that you think should be included.
EDIT: Forgot to include the genie chart, sorry
