First, ensure that you are connected to your Klei account. Then, on the main screen, click 'Host Game'. You can then create a new world and adjust the settings :
- Choose the playstyle
- Add caves or not (beware: if your device has 4GB RAM or less, caves will be automatically disabled to prevent the game from crashing, and you won't be able to add them. However, you can join a server with caves without any issue)
- Choose the name of your server and add a description
- Add a password if you want (recommanded if you want to play with your friends only)
- Choose the number of players
- Choose PvP or not
- Choose to make your server public or local only (LAN).
In the 'Forest' tab, you can adjust your world settings (world's size, starting season, number of ressources and creatures, Giants, mutations, etc.)
