Tinder wants to set the record straight about how its platform ranks and shows people potential matches, so today it published a blog post on the subject — but still kept things fairly vague.

The company’s Elo score was a “hot topic” a few years ago, according to the blog post, but the ranking feature has now been depreciated.

The idea behind the Elo score was that Tinder would rank people by attractiveness.

Elo scores are used to rank chess players, too, but in the context of Tinder, the more people that swiped right (or Liked) a person’s profile, the higher their assigned score went up.

Their card would then be served to other people with a similar score, thereby keeping the most desirable people interacting with one another.

On Tinder, where profiles are relatively limited in scope, a person’s looks often fuel much of the desire to match, so people speculated that these scores kept hot people talking to one another and left undesirable people to wallow with a low ranking.
