The basic mechanics in the Single Player Campaign are the same as in multiplayer, with the following exceptions: Each level also has varying Gold and Elixir rewards that can be raided from storages and Town Halls. Achieving all 150 stars satisfies the “Get those Goblins!” achievement worth a total of 35 Gems. There are currently 50 Single Player levels, and each level has 3 stars that can be achieved for a maximum possible 150 stars from all levels.
Single Player Campaigns are battles against NPC Goblins and their preset villages.
