The full community rules are on the Rules page. By playing on somtum.fun, you agree to them. This page adds the rules for submitting beatmaps.
Submit maps from the editor in TumThai or osu!(stable). Only the set's owner can update it, and nobody can once it's qualified, ranked or loved.
You can't submit while your account is restricted or silenced.
A set has 1 to 128 difficulties, all with the same artist and title.
You can have 4 sets in progress, plus 1 more for each of your ranked sets (up to 8). Supporters get 8, up to 20. Sets untouched for four weeks don't count.
Don't submit maps that aren't yours, or someone else's map under your name.
Don't submit content you don't have the right to share. Copyright holders can ask us to take content down at
[email protected].
To get a map ranked, see the ranking procedure. For how to map well, the osu! ranking criteria are a good guide, and our Beatmap Nominators use them too.
