About Agma.io

You start out as a tiny cell. You grow by eating dots scattered across the map and any cell smaller than you.

Power-ups are layered on top of the classic formula: items like speed, shields, and mass boosts appear on the map. You can also split your cell to lunge at a rival further away, which is the game's most critical move.

Why do kids love this game?

Watching your growth happen right on screen is satisfying. Learning the split move is a genuinely fun skill to master.

Is this game safe for kids?

Yes. The screen just shows colorful circles; there's no blood or disturbing content.

• Don't split in a hurry: splitting leaves you vulnerable, so only use it when you're sure you'll catch your target
• Stay away from spikes: crashing into a spike while big breaks your cell into pieces and turns you into easy prey
• Don't get boxed in: being chased near the map's edge leaves no way out, so stay as central as you can
• Use spikes while small: a small cell can hide behind a spike where bigger rivals can't follow
• Save your power-up: using a shield to escape is far more valuable than burning it on an attack
