The browser version takes a while to load the first time, and runs slower than the Windows client.

First time playing?

  1. Install and open the client (or press Play now).
  2. The first start downloads the game files, which can take a few minutes. Later starts are quick.
  3. Log in with any username and password. A new name creates your account.
