Can I play and compete with others on Sonolus?

Yes. Sonolus supports solo play, playing together with other people, and competing against other people. The site describes a "vibrant world of rhythm games" built around connecting with other rhythm game lovers, creating and sharing levels and replays, and taking part in different game modes. What makes this possible is the combination of a script-powered engine system and a range of community-run servers.

What the platform actually supports

Based on the official site, Sonolus is positioned as a "Next Generation Rhythm Game" with three broad modes of engagement:

• Solo play — you can play on your own.
• Together with other people — the site explicitly mentions playing "together with other people."
• Competing against other people — the site also explicitly mentions "competing against other people."

The site frames all of this as part of a broader community: connecting with other rhythm game lovers, and creating and sharing your own levels and replays.

How the social and competitive side is built

Two features on the site explain how multiplayer and competition work in practice.

Script Powered

Sonolus uses a scripting system that the site describes as "powerful and performant." With it, creators can build "any rhythm game engine imaginable" — whether replicating an existing game or designing an entirely different engine.

This matters for multiplayer and competition because game modes, rules, and scoring behavior are defined by these scripts rather than being fixed by a single built-in game. Different engines can produce different competitive formats.

Servers

The site states there is "a wide variety of servers available for different game modes." Servers are the mechanism through which different modes — including the social and competitive ones — are made available.

If you want to play with or against others, the practical path is to look at the available servers and pick one that hosts the game mode you want.

What you can do, in short

Where to go next

The site links to a Sonolus Wiki and a GitHub presence, which are the natural places to look for specifics on servers, game modes, and how to get set up. The site also offers downloads (an .ipa for iOS sideloading and an .apk for Android) if you haven't installed it yet.

One practical note: because servers host different game modes, the exact multiplayer and competitive experience depends on which server and mode you choose — so if a particular competitive format is what you're after, check the server list first rather than assuming a single unified mode.
