Sprunki: A Browser Music Mixer with a Hidden Horror Mode

What Is Sprunki?

Sprunki is a fan-made Incredibox-style mod that turns beat-making into a drag-and-drop toy. You line up a cast of odd characters on a single stage, and each one loops its own layer of sound — a kick drum, a bassline, a synth hook, or a vocal chant — all locked to the same tempo. The result is a layered track you build in real time, with no music theory required. It runs entirely in the browser, so there is nothing to install.

What separates it from a plain music box is the so-called "Cursed" mode. The bright, cartoon versions of the characters hide a second, distorted set of animations and a much darker soundtrack. Triggering that shift is the part players talk about most.

How to Play Sprunki

The stage has a row of empty slots and a tray of characters beneath it. Click or drag a character onto a slot to add its loop; click the character again to mute it, or drag it off to remove it. Because every layer snaps to one global beat, your mix stays in time no matter what order you add things.

To reach Cursed mode, remove the character on a specific slot (usually the one supplying the melody) and watch the others warp. The audio drops from upbeat pop into a muffled, glitched horror score, and the character art melts into its creepy counterpart. You can flip back and forth, so the horror layer is something you control rather than a spoiler you lose.

The Characters and Sounds

Each character has one job in the mix. The percussion characters lay the backbone, the bass characters add weight, the melody characters carry the hook, and the vocal characters chant or beatbox on top. Part of the fun is figuring out which combination sounds full versus which ones leave a gap you want to fill. Some versions add a "secret" character that only appears once you have triggered Cursed mode.

• Start with rhythm. Drop a drummer and a bass character first so the loop has a foundation before you add melodies.
• Mute, don't delete, to test. Clicking a character to silence it lets you hear what that layer was really doing.
• Hunt the Cursed trigger. If the visuals look too happy, try removing the melody slot — that is the usual switch.

Tips for Your First Mix

Don't overthink the "song." Sprunki is about quick experimentation: add a character, hear the change, remove it, try another. Because combinations number in the thousands, no two sessions sound alike, and the fastest way to learn the cast is to mute and unmute each one while a simple beat plays underneath.
