Best Tips for New Players to Play Tower Defense Games

• Prioritize chokepoints. Place towers where enemies must pass, maximizing damage per tower.
• Balance tower types. Mix single-target towers for bosses and splash towers for large groups.
• Upgrade selectively. Upgrading a central tower often gives more value than adding many weak towers.
• Save for emergencies. Keep some resources to handle unexpected waves or mini-bosses.
• Learn enemy traits. Some enemies resist certain damage types or move faster—plan accordingly.

Common Tower Types in Tower Deefense Games Online
