Boom Beach Private Server Switcher allows you to connect to Boom Beach Private Servers, automatically modifying your hosts file.
List is not really full of servers. Flamystic is in Alpha and is out from less than a month, so lots of features will not work.
I remember in addition that the status of the server is not updated automatically, so if you try to log on and the game isn't working, may be possible that the server is offline. I'll try to update the list of servers as much as possible.
If Boom Beach start crashing don't worry, just go to Settings->Applications->Boom Beach and click Delete Data, restart the gameand it should work!
REMEMBER TO LINK THE GAME ON GOOGLE PLAY GAMES TO AVOID YOUR ISLAND TO BE LOST!
For every questions, problems or everything else don't hesitate to contact me!
I'll do my best to reply A.S.A.P.!
