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 idea behind the Elo score was that Tinder would rank people by attractiveness. Their card would then be served to other people with a similar score, thereby keeping the most desirable people interacting with one another. Tinder, unlike other apps, only requires users to input their age, distance, and gender preferences. Tinder adjusts potential matches a user sees every time someone acts on his or her profile, it says. This algorithm identifies patterns around likes. If I like one guy, and so does another woman on the platform, she and I might have the same matching taste. Tinder feels like a free-for-all app, where truly everyone exists, but as the platform grows, it needs to order profiles in a somewhat personalized way, or else finding a match would feel impossible.

Glicko was chosen over its main alternative, Elo. Glicko’s main improvement over its predecessor is the inclusion of a ratings deviation RD , which measures the reliability of the rating.

By using RD, the matchmaking algorithm can compensate for players it has little or incomplete information about. A volatility measurement is also included to indicate the degree of fluctuation in a player’s rating. The higher the volatility, the more the rating fluctuates. Volatility changes over time in response to how you play the game. During periods of stability, your volatility should remain low, and reciprocally.

The ladder is an integral part of the Showdown experience, a driving force for players to continue playing and seek higher achievement and a source of endless frustration for many. Yet despite the ladder’s popularity, few know how it truly works, and many often throw around terms like “ELO” and “Coil” without really understanding what they mean. While skill rating systems might seem simple—win a game and you gain some points, but lose a game and you lose some points—they vary greatly in implementation, as there are many ways to try to condense player skill into a simple number.

Players who have been around for a couple of years may remember Showdown changing its primary rating system to Elo after using ACRE estimates of Glicko-2 don’t worry if these terms look like gibberish; they’ll be explained later , which angered many, as their hard-earned ladder ratings were reset.
