PlayOK

Kurnik (PlayOK is English alias, but both adress goes to same site) is a Polish server for many (40+ for English) kinds of games, like Ludoteka or Yahoo! Games. Support for English (and many other languages) is provided.

In Go, there are usually about 200-300 players online of mixed but typically lower ranks:

The server previously offered ladders and regular tournaments, but these features were removed.

Some differences from most servers to be aware of:

• The scoring process can be difficult, captured regions are not highlighted so players need to double check that all dead stones are marked correctly.
• Colors are not random; the player who set up the room chooses the color he likes. There are many Black-only players.
• There's no mapping from Elo ratings back to Kyu/Dan ranks so it can be difficult to understand the relative strengths of other players.
• AGARules is used. If opponent disagree with dead groups, if no move is made, then scoring system assumes that all not removed stones are alive.
• Only Canadian timing is offered, with a fixed 25 moves per period. For example, "15+5" means "15 minutes plus 5 minutes per 25 moves". The period time is misleadingly labeled as byo-yomi.
• Impossible to set up handicap games. (You may use passes to allow Black to play successive moves at the start if agreed in advance)
