If You Quit From The Battle You Can NOT Win

As Clash of Clans approches its first birthday, there are some who just
weren’t strong enough to keep clashing. But don’t let quitters bum you
out, they are actually super fun to raid ! Spotting abandoned villages
is actually one of the most important Clash of Clans strategies for
farming. Some hints are fairly obvious, but others are much more
subtle. Learn them all, and get good at searching for them during your
free 30 second inspection time. What to look for:
Tombstones: These show you that
someone else has already drilled this base, they are a good sign that
traps have been sprung too. Some chiefs leave them around as a trick,
but I dont run into that too much.
League Badge: Anyone who has at least on
win in the current 2 week league will have League Badge. You can
tell when a new League starts, because your own League Badge will
turn blank with a dotted line. Past a few days into a league, if you
encounter clashers without a league badge, it means they aren’t
attacking (and winning). That’s a pretty good sign they aren’t active.
Sleeping builders: Clash of Clans is all about
upgrades, painfully slow upgrades. Given that this is a central aspect
of the game, it is unusual to find an active player who has no builders
busy at any given time. Look for the “zzz” above the builders huts. If
all of them are sleeping, chances are that chief has been gone a long
time.
