What is MooMoo.io?
MooMoo.io is a multiplayer gathering and base-building game. You begin with simple equipment, collect resources around the map and turn them into structures that support a longer run.
Windmills make a base worth defending
Windmills generate gold over time, creating something for other players to attack. Walls, spikes and your own positioning help protect that investment. Food is useful for recovery, so gathering only construction materials can leave you vulnerable after a fight.
How to play MooMoo.io
- Move with WASD and aim with the mouse to gather nearby wood, stone and food.
- Choose upgrades as you progress, keeping a reliable gathering tool and a way to heal.
- Select a structure from the hotbar and place your first windmill where you can defend it.
- Add defenses without sealing off your movement, then return to gathering while watching for approaching players.
Controls: WASD move · Mouse / Space gather or attack · 1–9 select item · Q food
A base needs a working exit
Imagine your windmill behind defenses with a gap you can move through. A fully cramped layout may protect the structure but trap you beside an attacker.
Tips for your next round
- Keep food available instead of spending every moment gathering building materials.
- Place income structures where you can reach them quickly when attacked.
