A Dark RoomBack to the main gameIdle World is a creation game where you build a planet out of cubes, starting from the moment after the Big Bang. You spend energy to place land and water, then watch trees, rivers, animals and humans fill in the world you shaped. It is free to play in the browser with no download, and it runs on a school or work machine where browser games are allowed.
What Idle World is about
Idle World is a clicker and simulation game built around one calm loop: spend energy, place cubes, and grow the next layer of a planet. You start with empty space and a few elements, then add ground, water, plants, animals and finally people. There is no countdown and no fail state, so the game is about steady building rather than pressure.
Controls for placing cubes
Idle World uses a single input, so it plays the same with a mouse or on a touchscreen.
| Action | Desktop | Mobile |
|---|---|---|
| Place a block | Left mouse button | Tap the screen |
| Move the view | Click and drag | Drag one finger |
| Keep growing | Repeated clicks | Repeated taps |
Growing the world in stages
Each new layer unlocks once the world can support it, and earlier blocks stay as the base for the next.
| Stage | What you add |
|---|---|
| Land | Cubes that form the surface |
| Water | Rivers, lakes and seas |
| Plants | Trees and greenery on land |
| Animals | Creatures the land can support |
| Humans | People who settle your world |
Tips for a fuller planet
A few habits help your world fill out faster.
- Build a wide land base before adding water and plants.
- Place water near land you want to grow on.
- Let energy recover between bursts instead of spending it all at once.
- Spread blocks out so the planet looks varied.
