K-pop Quiz Statistics: How Fans Actually Score

This is a live snapshot of kpopquiz.org: how many quizzes exist, how many times people have played them, how many groups and songs the catalogue covers, and which quizzes are genuinely hard once you look at real average scores. Every figure here is read straight from the database and refreshed regularly, so it stays honest instead of frozen in a screenshot taken months ago.

How big is the K-pop quiz catalogue?

The headline totals below count only what actually exists: published quizzes, real recorded plays, active songs in the catalogue, and every group the platform knows about. They move as the library grows and as people play, so read them as a current measurement rather than a fixed claim. They are cached and refreshed on a schedule rather than recomputed on every request, which keeps the page fast without letting the numbers drift far from reality.

One clarification worth making, because a lot of quiz sites blur it: the group count is how many groups exist in the catalogue, not how many currently have quizzes attached. Plenty of groups are catalogued for the blind test and the song data long before anyone writes a quiz about them, so the number of groups with at least one published quiz is smaller than the catalogue total. Both numbers are useful, but only if you say which one you mean.

Which K-pop groups get the most quiz plays?

Ranking groups by the total plays across their quizzes shows where fan energy actually concentrates. It tends to be a mix of the biggest acts and whichever fandoms are most quiz-happy right now, and it shifts over a season rather than staying fixed. The ordering below reflects genuine recorded activity, not editorial picks.

Reading it right: a high play count means a group has both a deep set of quizzes and an audience that keeps coming back. It says nothing about whether those quizzes are easy or hard, which is a completely separate measurement.

What is the hardest K-pop quiz by average score?

The most honest measure of difficulty is not the label on a quiz but how people actually score on it. The tables below rank quizzes by their real average percentage, counting only quizzes with at least 30 completions so that a handful of lucky or unlucky runs cannot distort the picture. Out of 246 quizzes that clear that bar, these sit at the two extremes.

How are these numbers measured?

Average score is the maintained running total of points divided by the number of completions, then normalised by the quiz's real question count so that a five-question quiz and a twenty-question quiz sit on the same zero to one hundred scale. Values that come out impossible, which happens when a quiz was edited after people had already played it, are dropped rather than patched. That is why a quiz you remember struggling with might be absent from the tables above: it may not have enough clean completions yet to be ranked fairly.

Plays count every finished attempt, including repeat runs by the same person, because replaying a quiz you love is a real part of how fandom works and pretending otherwise would undercount genuine activity. There is no weighting, no smoothing and no editorial adjustment anywhere in these tables. When a number here looks surprising, the surprise is in the data, not in the presentation of it.

Because the ranking depends on a minimum number of completions, newer quizzes take a while to appear. A quiz published this week is genuinely playable but statistically invisible until enough people finish it, which is the correct trade-off: a 3-play average is noise, not information. Currently 246 quizzes clear the bar, and that pool grows steadily as the catalogue is played.

Where can I see the live numbers?

Every figure above is a snapshot from the same database that powers the site, and the stats page carries the fuller picture, including the current hardest and easiest quizzes and the week's most-played fandom. Between the 10 most-played groups shown here and the full library, there is more than enough to find your next challenge. All of it is free to cite with a link back.
