In this Tower Defense game with giants and dwarfs you're going to build defense towers to stop your enemy from invading your land as long as you can. When the enemy breaks through your line of defense you'll lose HP (Health Points). If you want to build or upgrade a tower you'll need gold. You can build different towers; each tower has different qualities (and thus advantages and disadvantages). Don't let the enemy reach your blue flag!
Move your character over the field by clicking on the ' move' button, and then on a spot on the map. After this, you can build a tower.
