Sprunki Phase 3 is not a hidden mode in the original game but a fanmade mod that continues Phase 1 and Phase 2. To play Phase 3, you just need to find the support website, select Phase 3 and start playing directly on the browser. In this mod, the characters transform into more terrifying versions, the sound becomes darker and more haunting, but still retains the familiar music mixing mechanism. This is the reason why Phase 3 is loved by the community: both creative and creepy, bringing a completely new experience to sprunki fans.
