Once you start the game, you’ll have access to wooden walls. These walls come in at a pretty low level (level one), which means they’re not worth much when high-level barbarians come barging into your base. Try to upgrade these wooden walls to level three as fast as possible (attain for level four or five if you can, too). These walls will end up being your strongest defense, so make sure you purchase all the available walls within your level. Place these walls all around your base so that no opening pathways are available for entry. Let those attackers break down your walls and struggle; don’t let them ease on in without much trouble because you mistakenly left a lane open.
