About the Game
Sprunki Phase 4: Decay by the Day is a glitch-noise music game set inside a decaying sound experiment. It’s weird, dark, and surprisingly creative. You don’t just select beats or vocals—you inject corrupted audio into bizarre creatures and watch them decay in both sound and appearance. Each performer reacts differently to the noise you give them. Some glitch out. Some fall apart. Others just melt into chaos.
We added this strange music game to our website because we know you enjoy interactive sandbox games that are unpredictable. There’s no score. No timer. You just drag different sound modules into the lineup and see what happens.
Let’s play the game on our Y9FreeGames website and see how your sound mutations evolve—or fall apart.
🎮 How to Play:
- Use your mouse or touchscreen to drag sound icons from the lower panel onto different characters.
- Each icon represents a different sound: percussion, glitch noise, distortion, basslines, etc.
- Characters will begin performing based on the icon you placed, but their sound and look will deteriorate over time.
- Click icons again to stop or change the sound.
- There is no objective—you’re creating an evolving soundscape of decay.
