somtum.fun is a free osu! private server with full lazer support, open to players worldwide. You play lazer here with TumThai, our version of osu!lazer, and your lazer scores share one leaderboard with osu!(stable) and the old 2008-2015 clients.
Already play osu!lazer? TumThai can use your lazer beatmaps, skins and replays: see bringing your osu!lazer beatmaps and replays. From osu!(stable), see Upgrading to lazer.
osu!lazer only connects to osu.ppy.sh. TumThai is the same game, set up to connect to somtum.fun, and our anti-cheat trusts it, so its scores are submitted. You can connect another lazer client (see Connecting with another lazer client), but its scores aren't submitted.
TumThai has two streams: TumThai, and TumThai!Next, a faster, experimental stream for players who want the newest performance options first. Switch in Settings → General → Updates.
