First World Christmas adventure: a flying Santa and reindeer, pets, a sparkling tree, snowy mountains, a railway and a UFO beneath the moon.
Adventure awaits.World concept artwork.

Free. From William Rydh to all of you.

It starts with a small idea

Build a home.
Or something nobody has seen.

A path over a hill. A house among the trees. A strange tower only you understand. Dig, gather materials and keep building on your own ideas.

Explore snowy peaks, valleys and huge caves. Find blue ice caverns and throw snowballs with other players. Watch your fishing float, reel in a catch and feed your pet. Bees visit flowers and fish leap from the water.

Choose unlimited creative building or survive with food, warmth and shelter. At night, UFOs bring hopping brainrots; cave creatures leave useful mining bombs. Work your way from a stick to a sword and a light blade. Your dog, cat or bird helps defend you and gains better equipment as you progress. Pets keep following when hungry, and birds can join you in the sky.

Pigs, cows and rabbits live peacefully in the world. They never attack. Hunt for food for you and your pet, or gather berries along the way.

Make a workbench, share supplies in chests, light your way with torches and open caves with mining bombs. Defeat brainrots across three nights to earn a parachute supply drop. Find your camp, supplies, snowy mountains and other players on the map. Water flows into holes connected to lakes and rivers.

Connect wires, logic gates and memory blocks. Build counters, flashing light shows and your own railway. Browse every building part directly in your inventory.

Open the full-screen map to find players and the world’s inhabitants. On mobile, drag to explore and pinch with two fingers to zoom.

First World is in active development. The world is already open for you to explore and help shape.

One world. Three different moods.

  • Summer

    Green forests, flowers and butterflies.

  • Halloween

    Pumpkins, autumn colours and eerie nights.

  • Christmas

    Snow, festive lights and winter adventures.

Birdsong, winter ambience or an eerie Halloween atmosphere stays in the background while music comes and goes. A large moon and gently twinkling stars light the night as UFOs cross the sky. Change your theme in the game menu whenever you like.
