About MooMoo.io
Gather wood and stone, build walls and windmills, defend your base. The windmill economy and hat system made it a genre of its own. 2017, Sidney de Vries.
MooMoo.io is a free survive and build io game (classic, building, free-for-all). Gather, craft, build a base, defend it. MooMoo.io made the template and the rest went in every direction from there. It ran when last checked, on 2026-10-30.
The game loads from moomoo.io in a frame. Its own terms, privacy policy, ads and accounts apply inside it, and a save made here is separate from one on moomoo.io. If you already have progress there, open the game on its own site. How the frames work.
