Mastering Bloons TD 6 requires a thorough understanding of the various bloon properties that attempt to breach your defenses. Each type presents unique immunity mechanics and operational challenges that can quickly overwhelm unprepared players. Knowing how to adjust your tower placement and upgrade paths is the key to surviving higher rounds.
Standard and Elemental Bloons
Basic colored bloons make up the early rounds and rely mostly on speed and density to push past your defenses. Pink and Yellow bloons are especially fast, forcing players to invest in high attack rate towers or area-of-effect damage early on. Purple bloons introduce immunity to energy, plasma, and fire attacks, making magic-heavy setups vulnerable if not complemented by physical damage.
Lead bloons present the first major armor test by completely ignoring sharp projectiles like darts, tacks, and arrows. To pop them, players must utilize explosive damage from Bomb Shooters, heat-based attacks, or alchemy buffs. Installing an Alchemist with the Acidic Mixture Dip upgrade allows nearby sharp-shooting towers to easily melt through lead casings.
Specialized Stealth and Metallic Threats
Camo bloons remain invisible to standard towers unless explicit detection options or village buffs are provided. Ninja Monkeys naturally detect these sneaky threats, while the Radar Scanner upgrade on the Monkey Village grants vision to all nearby defenders. Stripping camo properties using Submarines or Mortar Monkeys is another efficient way to maintain map control.
Black and White bloons bring specific immunity traits that counter popular tower archetypes. Black bloons immune to explosions can slip through heavy bomb choke points, whereas White bloons resist freezing effects completely. Zebra bloons combine both properties, requiring balanced strategy combinations like sharp physical darts or plasma attacks to popping them reliably.
Fortified and MOAB-Class Targets
Ceramic bloons act as sturdy outer shells that require multiple hits to break open, frequently clumping together to overwhelm single-target towers. When fortified, their health doubles, turning late-game waves into massive damage walls. High-damage cluster attacks or slowdown abilities like Glue Gunners are critical for keeping these dense rushes manageable.
MOAB-class blimps represent the ultimate endgame obstacles, requiring massive single-target damage output to destroy. Larger variants like the BFB, ZOMG, and the speedy DDT bring severe combinations of speed, camo, and lead properties. Utilizing HERO abilities, Spike Factories near the exit, and Super Monkeys ensures your defense can withstand these massive aerial threats.
