If you wonder how to change servers in Crab Game, there is no exact way to do it. However, this only applies if you are trying to change servers from within a server, as there is no option to do it.
Because of this, you will need to instead simply leave your current server and go back to the server list or lobby. Inside the server list, you will see a vast list of servers created by players of the game.
If you want to choose a new server to play on or change servers, you must select one of these servers. Beyond this manual method, this is the only way you can change servers in the game.
