This is a scala implementation of the popular Glicko2 rating calculator commonly used to compare chess skill, and other 1v1-style games.
It is meant to be usable as a library from Java and Scala alike. See unit tests for example usage: https://github.com/wfreeman/ScalaGlicko2/blob/master/src/test/scala/com/skeweredrook/scalaglicko2/TestGlicko2.scala
The implementation is as close as possible to the example in this document: http://www.glicko.net/glicko/glicko2.pdf
Thanks to Mark Glickman for his work to improve ratings calculation. His ratings page: http://www.glicko.net/glicko.html
