+1 Black Slime Evolution

About +1 Black Slime Evolution

+1 Black Slime Evolution is a Roblox-style evolution simulator where a living black slime gradually consumes your blocky hero. Starting small, it absorbs an arm, then the head, then the torso, and finally engulfs the entire body in tendrils and spikes. The game blends incremental training with arena combat across three distinct worlds, pushing the slime through 10 evolutionary forms, each one unlocking a new area attack.

How to Play +1 Black Slime Evolution

Begin in the lobby by standing on a training station — doing so feeds the slime and raises your level. Once ready, walk into a portal to select one of the three arena stages. Inside, the slime attacks incoming zombie waves and bosses automatically; the player's job is to stay close and dodge the red circles telegraphed by bosses. After clearing every wave, step onto the win pad to bank wins. When both level and wins meet the required threshold, head to the altar to evolve into the next of the 10 forms.
