Click a tower to upgrade it (up to level 4) or sell it. Bosses arrive every 5 waves!
A tower defense strategy game. Waves of goblins, speedy runners, armoured knights and huge bosses march along the road toward your castle. Spend gold to build towers beside the road: archers shoot fast, cannons blast whole groups, frost towers slow enemies down and magic towers zap several monsters at once. Every monster you defeat gives more gold to build and upgrade. Survive all twenty waves to win.
