Let's get better together

Study Go

Ask stronger players to help review your games, study pro games or tsumego. We also organise lectures with strong teachers. The global idea is you get taught by the stronger while you teach the weaker.

See our study schedule in our calendar

Play Go

Playing long serious games is very important to improve. Our league system encourages you to do so in a friendly yet competitive environment. On top of that we reward our winners with cool prizes every month.

Check out our leagues


We are a friendly active online community of Go players from all around the world. OSR is run by volunteers, community driven and all free for everyone to come enjoy the beautiful game of Go.
