Gold and elixir (loot) is the whole purpose of the game. Without loot, there would be no way to upgrade your defense or your army. Therefore, a valuable skill to this game is know exactly what league to find these resources in. Of course, a Town Hall 4 is not going to find loot in the same league as a Town Hall 10 so it has to vary between Town Halls. Look below to find your Town Hall level and it will tell you around what league you could find the best loot in.
Town Hall 4– Bronze 1: Right now, just starting out it should be fairly easy to get your building upgraded. The key is not to get to many trophies or higher levels will start taking your resources from you.
Town Hall 5– Bronze 1: The same as Town Hall 4, you are still relatively new, so you don’t want to extend your trophies too high. You should be able to find some really low Town Hall 6s and Town Hall 7s in this league.
Town Hall 6– Silver 3: As you start to max your base and not upgrade your Town Hall as fast, you will need more loot to do so. Silver 3 is a great place to find fellow Town Hall 6s that you can raid for relatively lots of loot.
Town Hall 7– Silver 1: Town Hall 7 is the beginning of elite players. You start winning defenses easier and for that case you need to jump up two leagues to find other Town Hall 7s (and maybe a couple Town Hall 8s) for maximum loot possible.
Town Hall 8– Gold 2: Gold 2 is the mother-load of all loot for Town Hall 8s. It is the best Town Hall loot wise since you have the troops to beat Town Hall 9s, but still get decent loot off Town Hall 7s. You need to be in a place where they come together, so you can get a variety of raids.
Town Hall 9- Gold 1: At Town Hall 9, anything is possible. Its still hard to get to Champion, but you start getting level 6 troops which enables you to beat some Town Hall 10s (especially rushers). Gold 1 is where all the gemmed Town Hall 10s lurk.
Town Hall 10– Crystal 2: At this point it is hard to get loot off anyone but fellow Town Hall 10s. Crystal 2 is the ideal place to farm since you get some Town Hall 9s, but mostly Town Hall 10s farming. This is the only place to get loot for Town Hall 10s.
