Merge Tower Defense Tips for Beginners
Even with free diamonds from Merge Tower Defense codes, you’ll need a solid strategy to get ahead. Here are a few tips to level up your game:
Focus on Merging Early Units
Start with merging low-level units to make space and create stronger defenders. The faster you merge, the better your defense.
Spend Diamonds Wisely
Don’t waste your diamonds right after redeeming codes. Prioritize purchasing weapons or upgrades that help you progress through bottlenecks or tough waves.
Positioning Matters
Place your towers at choke points or near corners to maximize damage output. Think of your base layout as a tactical map.
Don’t Hoard—Upgrade!
Always upgrade or merge when possible. Saving units without upgrading can lead to sudden failure during stronger waves.
