Robbie: Become a slime
About Robbie: Become a slime — 3D io game of absorbing and collecting
Robbie: Become a slime drops you into a 3D io arena where your creature grows by absorbing other players and collecting bonuses scattered across the map. The game draws inspiration from popular io projects and blends strategic thinking, speed, and agility into real-time competition against other players. Small yellow, blue, and purple spheres are scattered across a green and cyan checkered floor in several scenes. The pace is fast, and the core tension comes from knowing when to chase smaller opponents and when to dodge the ones that outsize you.
How to Play Robbie: Become a slime — grow by absorbing and avoiding stronger opponents
The goal is to grow your creature as large as possible by absorbing other players and picking up bonuses on the map. Competing in real-time means constantly reading the arena: smaller opponents are fair targets, but running into a stronger player ends your run. Strategic thinking, speed, and agility all factor into how long you survive and how large you grow.

If you prefer absorbing the environment itself, Black Hole WWII io lets you devour buildings, vehicles, and players as a black hole tearing through a wartime city.
