Advanced Tips and Strategies

Once you’ve mastered the basics, these advanced strategies will help you dominate the leaderboards and maximize your efficiency.

Wave Management Techniques

1. Economy Waves

• Identify waves with lower enemy density (typically waves 5, 10, 15, etc.)
• Use these waves to save resources and build economy
• Sell and replace units strategically during these waves

1. Boss Wave Preparation

• Begin preparing 3-5 waves before boss encounters

• Sell lower-tier units during waves to afford immediate upgrades
• Time unit sales to maximize resource gain (typically just before enemy drops)
• Keep a reserve of at least one basic unit for emergency placement

1. Upgrade Efficiency

• Focus on upgrading one unit to max rather than spreading resources evenly
• The first 3 tiers of any unit provide the best cost-to-performance ratio
• Consider the “80/20 rule” – 80% of resources to 20% of units

1. Event Maximization

• Prepare resources in advance of limited-time events
• Focus on event-specific units that often have superior abilities
• Complete event challenges first for bonus rewards before regular gameplay
