Players who have not yet set an avatar, please update it by going to "SETTINGS" on the menu that appears after you click on your username at the top right of the page:
Then click on "Avatar": https://www.bitsler.com/en/settings/avatar
Click on the white square and choose your picture, once you are done click on "UPLOAD AVATAR".
PS: Zoom in on your picture by using the sliding bar.
Now if you are level Bronze II or higher, you can start receiving rains from the chat ;)
PS: not having an avatar will block you from the chat.
