OGS has a new Glicko-2 based rating system!

Yeah, it doesn’t even have to be abuse. I’m not sure, but I suspect I time out more in positions where I’m losing, just because I tend to play faster in easy positions. I have no intent to abuse the system, but if the timeouts are not distributed evenly, it will skew the results.


“10k” is 9.0k - 10.0k or 9.5k - 10.5k ?
Is it 1600 - 1700 for example ?
I don’t understand what I see on graph.

Well, I’m a paper tiger now. Hear me roar.

Maybe when new system stabilize we should make a survey of these ranks and update sensei’s library rank comparison page.


If the new system continues to hold up over time will the old one eventually be removed?

Congratulations! Looks like this was a lot of work. Excited that now people will be matched up more accurately!


10k is 9.0k to 10.0k . The ratings to ranking math is not as pretty as it is under the EGF model, it’s 850*exp(rank*0.032) where 30k is rank 0. For instance, 9k is 1664.4 and 10k is 1612.0.


Yep, probably in a couple of weeks if everything is still looking good by then.

Looks great on PC, but when will the update go through on iOS? :drooling_face:

We need someone to write a manual for dummies like me. So far all this “list of recent games” doesn’t make much sense.

Fwiw, I really like the breakout, have been hoping for it for a long time, and hope it stays. If some people find it misleading or confusing, maybe it can be hidden by default? But it would be nice if it remains available in some form even if it’s not shown by default


In the chat room, sometimes ranks are showing the old number and sometimes the new number. Here’s a shot showing the mix:

Kaworu Nagisa is actually 6d now, and sometimes shows in chat as 6d, but is currently showing as 3d.

Also, suggestion, cap all displayed ranks at 9d. Even if your rating is 13d, show a 9d rank, not a 13d rank. Tradition and all other servers kinda require 9d to be the max shown?


On “Games” page ranks of players displays in old system
also in profile while game continues

I noticed in Ten’s games, his rank is shown as a dan rank when he talks in chat. I never paid attention to how it looked before, but it shows him as an 8d in some chats. Got curious and found one of Haylee’s messages as a 10d.

I’m assuming they should be consistently shown as their pro ranks?

“Games against bots which result in a timeout will not be rated.”

Should that only apply when the bot times out? So we aren’t encouraging humans to time out on purpose vs bots every time they think they are going to lose.

@jgk that was an old bug that I believe got fixed. Maybe old chat rooms still show the way it used to instead of showing the new way? Hmm.

Maybe we can lure @Ten into a game to say something to test it. :slight_smile:

Thanks @jgk, I mentioned it in the bug report database. It was fixed 3 months ago but I think it slipped past the glicko changes.

While I understand the evolution and improvement of OGS to a new ranking system, and for the record I say it is a good thing, the disclaimer that only a slight movement in your current ranking, is totally untrue. I just checked my “new” ranking and I went from 16K to 20K, I am devastated and angry. It as thought my 500 wins and hard work to even maintain a 16K means nothing! All they years playing here, and getting stomped, learning, striving to be better all has been trashed.

Should I have played better? That goes without saying, it easier to visualize SDK when you’re 16K vs 20K, it might not matter to most, but it matters to me, I hope there will be a formal process for those who dispute the rank issued by this new process, as I will be the first to protest, I know I am better than what has been handed to be, and I am willing to prove such.

Hello @kissmecomix,

maybe it’s a good idea calm down and wait for a day or so until the new system has worked through all players and all games (I must admit that I myself don’t really understand the goings-on under the hood).

But I’ll mention @anoek anyway so he can maybe explain some more. I think the ranks are still changing, and there may be a few bugs to weed out.

So … please don’t despair yet, OK? :wink:

@kissmecomix your go skills have not changed a bit from this ranking system change. It does not matter if your rank is 5dan or 15 kyu. You will still be able to play against people who are at the same level as you are.

If this is the case then simply playing is “proving” and the new system should pretty fast put you in to the correct place in ranking (if there are no bugs)
