somtum.fun is a fan-run private server for the rhythm game osu!. It has its own accounts, rankings, beatmaps and community. It is not affiliated with ppy Pty Ltd, and your osu! account and scores on osu.ppy.sh aren't shared with it.
All downloads are on the download page. The easiest way is the Somtum Launcher: it installs and updates everything below and starts the game for you.
osu!.exe. Keep pkms.dll (our anti-cheat) next to osu!.exe: without it your scores aren't submitted. They need Windows and .NET Framework 3.5 (a few 2015 builds need .NET Framework 4). Can't find the build you want? Ask for it in our Discord server or on the forum.Only these submit scores. From October 2026, our anti-cheat checks every client that plays here, and only the Somtum Launcher, the Somtum Patcher, TumThai and our rebuilt legacy clients pass. You can still connect other ways, and log in, chat, play and join multiplayer, but your scores won't be submitted, because the anti-cheat can't verify those clients:
-devserver: osu!(stable) started with -devserver somtum.fun (without the Somtum Patcher) still connects to somtum.fun, but its scores aren't submitted.Old clients (2008 to 2015) are different: only our rebuilt legacy clients can log in. An unmodified old build (with the hook or not), or one you modded or rebuilt yourself, gets "This old osu! build can't play on somtum.fun as it is" and can't connect.
This keeps the rankings fair for everyone. If your setup can't run one of ours, tell us in Discord.
TumThai can use the beatmaps, skins and replays you already have in osu!lazer. In TumThai, open Settings → Maintenance → Change folder location and choose your osu!lazer folder:
%AppData%\osu~/.local/share/osu~/Library/Application Support/osuTumThai then reads that folder instead of its own, so close osu!lazer first. To move back, choose another folder the same way.
Using g0v0's client, another lazer-based client, or osu!lazer with LazerAuthlibInjection? Fill in these settings:
| Setting | Value |
|---|---|
| API URL | https://osu.somtum.fun |
| Website URL | https://osu.somtum.fun |
| Client ID | 5 |
| Client Secret | FGc9GAtyHzeQDshWP5Ah7dega8hJACAJpQtw6OXk |
| Spectator URL | https://spectator.somtum.fun/spectator |
| Multiplayer URL | https://spectator.somtum.fun/multiplayer |
| Metadata URL | https://spectator.somtum.fun/metadata |
| Beatmap Submission Service URL | https://osu.somtum.fun/beatmap-submission |
| Non-g0v0 server | On (checked) |
You can log in, chat, spectate and play multiplayer, but score submission never works on these clients. For your scores to count, play on TumThai.
Make it in the game: open TumThai or osu!(stable) on somtum.fun and register there, not on the website. Then sign in to this website with the same name and password.
New here and not set up yet? You can also make your account from osu!(stable) started with -devserver somtum.fun, or from another lazer client pointed at somtum.fun. Keep in mind that you can't submit any scores until you play on our official builds: TumThai, or osu!(stable) through the Somtum Launcher (or the Somtum Patcher), or one of our legacy clients. See How do I connect?
You can have one account. Sign-ups through a VPN, proxy, Tor or a hosting network are blocked, and each network can make one account a day. If that stops you from signing up honestly, email [email protected].
Yes. Supporter tags are optional and help pay for the server.
Relax and Autopilot have their own leaderboards, rankings and pp, separate from normal play, in both TumThai and osu!(stable). Choose them on the rankings page and on beatmap leaderboards.
Every osu! beatmap, with the same ranked status as on osu!, plus maps submitted here by our mappers. Download maps in the game (osu!direct) or from the beatmap listing.
Every play on a beatmap the server knows is submitted and saved, with its replay, whatever the map's status. The status only decides what the play gives you, as on osu!:
| Map status | Leaderboard | pp |
|---|---|---|
| Ranked, Approved | Yes | Yes |
| Qualified | Yes | No. Qualified maps are ranked after 1 day (see the ranking queue). |
| Loved | Yes | No |
| Pending, WIP, Graveyard | No | No |
So a play on an unranked map that gave you nothing was submitted; it just doesn't count for rankings.
A score is really not submitted only when:
-devserver, your own modded client, g0v0 or LazerAuthlibInjection). See How do I connect?If your account is restricted, your scores are still saved, but they're hidden from everyone else: only you can see them (see Restrictions & appeals).
Read Restrictions & appeals. If you think it's a mistake, email [email protected].
The Somtum Patcher launches osu!(stable) on somtum.fun and keeps the session fair. While it is running:
opengl32.dll, d3d9.dll or dxgi.dll next to osu!.exe, the same way some cheats load. With one of those files there, your scores aren't submitted. Delete it and start osu! again. Any other DLL that isn't part of osu! counts as cheating.If you weren't using any of those and your score was still refused, email [email protected] from your account's email with your username and roughly when you played, and we'll look into it.
Courses of long osu!mania maps, from DanReform: pass one with 96% accuracy and no pausing, and it's on your record. See osu!dan for the rules, and the osu!dan page for the courses.
Staff give them. See User titles and User groups.
Yes, on the website: Username change (in the store). Everyone gets 5 free changes every 30 days, and Somtum Supporters can change it as often as they like. Some names can't be used (staff keep a list of blocked names).
If it doesn't work for you, email [email protected] from your account's email address.
Report players with the report button in the game or on their profile. Report bugs on our Discord. For anything serious, see Reporting abuse.
What the messages you might see in the game mean, and what to do about them.
Check your username and password; they're the same as on this website. Forgot your password? Reset it here. Signing up happens in the game, not on the website (see How do I make an account?).
You're logging in from a computer or network we haven't seen on your account. Sign in to this website, open the verification page and confirm the device there, then log in to the game again.
Older builds can't show the confirmation screen. Confirm the device on the verification page first, then log in again. If that doesn't help, use TumThai or the Somtum Patcher from the download page.
Only our rebuilt legacy clients can log in with a 2008-2015 build: an unmodified build (with the hook or not), or one you modded yourself, can't. Download the same build, already patched, from the download page. If it isn't there, ask for it in our Discord server or on the forum.
A program that reads or changes osu!'s memory is running (see Playing with the Somtum Patcher). Close it, then log in again.
osu!(stable) was started without the Somtum Patcher, or the Patcher was closed or stopped while you played. Close osu! and start it again from the Somtum Patcher or the Somtum Launcher.
The Patcher's files were changed or damaged (an antivirus sometimes does this). Download it again from the download page and reinstall it. If your antivirus removes it, add an exception for the Patcher's folder.
You can play, but your Somtum Patcher or legacy client has an anti-cheat version we no longer accept. Get the newest Somtum Patcher from the download page (or let the Somtum Launcher update), or download your legacy build again, then start osu! again.
Our legacy clients load our anti-cheat, pkms.dll, from their own folder, and scores need it. Make sure pkms.dll is still next to osu!.exe (an antivirus sometimes removes it: add an exception for the folder), then start osu!.exe again. If that doesn't help, or the message says it's out of date, download your build again from the download page and unzip it to a new folder.
There's a file such as opengl32.dll, d3d9.dll, dxgi.dll, dinput8.dll or version.dll in your osu! folder. These come from ReShade or similar tools, which aren't allowed (see Playing with the Somtum Patcher). Delete the file from your osu! folder, then start osu! again. You're not in trouble for this.
A file of your legacy client isn't the one we published: it was changed, replaced, or comes from another version. Download your build again from the download page and unzip it to a new, empty folder.
Download the newest Somtum Patcher from the download page. Old versions stop being able to submit scores some time after a new one is out.
Your Somtum Patcher is a version we no longer accept (usually because a newer one fixes a problem). The game stops so nothing is played on it. Download the newest Somtum Patcher from the download page, or let the Somtum Launcher update itself, then start osu! again. You're not in trouble.
The anti-cheat was loaded without the Somtum Patcher starting osu!. This happens when osu! restarts itself (after an osu! update, or from its own options) while the Patcher is attached. Close osu! and start it again from the Somtum Patcher or the Somtum Launcher.
The part of the anti-cheat that talks to our server was stopped. Most often an antivirus or firewall stopped it. Allow the Somtum Patcher's folder in your antivirus, close any tools that touch osu!, and start osu! again from the Patcher.
Something changed or froze the anti-cheat inside osu!. Close any program that reads or writes osu!'s memory (see Playing with the Somtum Patcher) and start osu! again from the Patcher. If you weren't running anything like that, email [email protected] with your username, roughly when it happened and your antivirus's name.
The anti-cheat found something changing osu! while it ran, and closed the game. Close the program it found and start osu! again from the Patcher. If it keeps happening and you don't know why, email [email protected] with a screenshot of the message.
osu! got stuck while starting (often while it updates, or while an antivirus scans it). Start osu!.exe once by itself, let it reach the main menu, close it, then use the Somtum Patcher again. If it keeps happening, delete osu!'s update and launcher cache files from your osu! folder.
Not an error: the Patcher is still checking in with our server. It can take up to 45 seconds, mostly on Linux with Wine. Wait for "Client verified".
osu! found relife in your Windows registry. Turn relife off (or reinstall it and turn it off) so it doesn't trip again. This is a warning, not a restriction.
A new account was made on the same computer as a restricted account. If that's a shared or family computer and you aren't the restricted player, email [email protected] with both usernames.
Staff locked the account. Email [email protected] from the account's email address.
The account was deleted on request or by staff. Email [email protected] if you think that's a mistake.
That's a bot account: it can only chat over IRC. Log in to the game with your own account.
Close some of the tournament client's windows and try again (see Tournament client).
Your score is saved as normal, it just isn't a dan clear. See osu!dan for each reason.
TumThai (osu!lazer) shows this under "Score will not be submitted" when you play a map from an osu!dan course. Dan courses are osu!(stable) only for now, so the play isn't saved. Play the map in osu!(stable) instead.
