Three Mines ‘Round is the first chapter of the Mastery Mode Tale in BTD6, introduced in Version 57. This new quest features a tougher version of the standard Bloon roundset, with additional layers and fortification making the incoming waves more challenging.
The chapter takes place on Three Mines ‘Round, a map where you can mine Bananite crystals to earn extra cash. These crystals are an important part of the map’s strategy, as removing them provides both additional space for your towers and a financial reward.
How to Beat Three Mines ‘Round
Step 1: Start Building Your Defense
Begin by placing your starting towers in positions with good coverage of the track.
The Bloons are stronger than in a standard game, so prioritize reliable damage and upgrades that can handle the additional layers.
Step 2: Start Mining the Bananite Crystals
One of the most useful features of Three Mines ‘Round is its Bananite crystals.
You can pay to start mining a crystal. After the required number of rounds, it is removed and you receive a cash reward greater than the initial investment.
Start with the cheaper crystals whenever your defense can safely handle the incoming Bloons. This will help you build up additional cash for stronger upgrades.
Step 3: Invest Your Mining Rewards
Use the money earned from mining to strengthen your defense.
Avoid spending all your cash immediately. The Mastery roundset becomes increasingly difficult, so make sure your towers can handle the stronger Bloons before committing to expensive upgrades.
Step 4: Prepare for Fortified Bloons
Keep upgrading your main damage towers as you progress through the rounds.
Since Mastery Mode adds extra layers and fortification to the Bloons, towers with strong grouped-Bloon damage and reliable MOAB damage are particularly valuable.
Step 5: Complete the Chapter
Continue mining crystals whenever it is safe to do so, and invest the additional income into your defense.
Keep upgrading your towers until you clear the final round and complete Three Mines ‘Round.
