About Moonch.io
Moonch.io is a free arena game about cows. You graze to grow, headbutt rival cows off a floating voxel island and try to become the heaviest cow on the meadow.
The idea
Most .io games are about eating dots. We wanted one where eating is a choice: a cow has to stop and stand still to graze, and standing still on a meadow full of bigger cows is a risk. Every fight is a little physics puzzle: weight, wind-up and the distance to the cliff decide who goes over the edge.
Made for every screen
Moonch.io runs in any modern browser on phones, tablets and computers, with no download and no sign-up. It is built in JavaScript with the three.js 3D library, with every block of the world, every cow and every sound made for the game. Your progress is saved in your browser.
Who makes it
Moonch.io is made by OP GAME, a small studio making free casual games for the web, YouTube Playables and our OP Game app. You can also play Moonch.io on op.game.
Free, with ads
The game is free. It is paid for by ads: a short ad may play before a game or between lives, and you can choose to watch a rewarded ad to revive or to double your coins. See our privacy policy for how ads use cookies.
