A little confused with Troops

[Stepsongrapes]

It's is possible to lose the game in the sense that you get your self to the point where you have too little cash and too little troop options.

As poster above said, it sounds like you're losing way too many troops in your current game.

For the most part, you shouldn't rely/expect troops to replenish. As mentioned, there will be limited replenishment at existing locations, the real supply of troops comes from advancing in the game to access new troop sellers.

So, that means your not losing because you don't know how to replenish troops, it's because you are needing to replenish troops too much.

The solution may be to start a new game (perhaps at a lower difficulty) and work on picking your battles in the right order so as to limit loses and preserve gold.

Progressing in the game requires a combination of doing the right thing tactically in battles, but also doing the right thing in the map phase by picking fights in a reasonable order and selecting the right troop combinations.
