Ninja Kiwi released Bloons TD 6 in June 2018 and has kept adding to it ever since, past 25 monkey towers split across the Primary, Military, Magic and Support categories. Every tower has three upgrade paths of five tiers, but you may only take two paths and the second one caps at tier 2, which is the single rule that shapes every strategy in the game. Rounds run to 100 in standard play, with the MOAB arriving at 40, the BFB at 60, the ZOMG at 80, the DDT at 90 and the BAD at 100.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness, factoring in damage, survivability, gear requirements, and how well they scale into endgame. New to the game? Start with our beginner's guide first.

A-Tier: Primary
Primary is a top-performing option in Bloons TD 6.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Dart Monkey | The cheapest tower in the game and the one everyone underrates. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Two path upgrade limit | A tower can reach tier 5 on one path while a second path is capped at tier 2, and the third path stays empty. |
How to Play Primary
Primary focuses on a balanced approach to content.
Why this build works: Dart Monkey does the damage and Two path upgrade limit keeps it running, which is why this sits at the top of the list. See our weapons guide for detailed equipment breakdowns.
Pros:
- Highest overall performance
- Straightforward gearing path
- Works in all content types
Cons:
- Popular pick, resources may be contested
- Needs specific gear to reach full potential
A-Tier: Military
Military is a strong option in Bloons TD 6.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Ninja Monkey | Fast, cheap and camo capable without any support. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Bloon properties and immunities | Black and White bloons resist explosions and freezing, Lead resists sharp attacks, Purple resists energy, magic and fire, and Camo cannot be targeted without detection. |
How to Play Military
Military focuses on a balanced approach to content.
Why this build works: Pair Ninja Monkey with Bloon properties and immunities and the build stops depending on a good start, so it holds up across most content. See our weapons guide for detailed equipment breakdowns.
Pros:
- Most versatile option
- Straightforward gearing path
- Works in all content types
Cons:
- Lower peak damage than S-tier
- Needs specific gear to reach full potential
A-Tier: Magic
Magic is a strong option in Bloons TD 6.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Alchemist | A support tower disguised as an attacker. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Monkey Knowledge and hero levelling | Monkey Knowledge points are permanent account upgrades that reduce costs and add small buffs, and heroes gain levels inside a match while only one hero may be placed. |
How to Play Magic
Magic focuses on a balanced approach to content.
Why this build works: Monkey Knowledge and hero levelling covers the gap Alchemist leaves open, so the build stays usable even when a fight goes badly. See our weapons guide for detailed equipment breakdowns.
Pros:
- Best survivability
- Straightforward gearing path
- Works in all content types
Cons:
- Slower clear speeds
- Needs specific gear to reach full potential
A-Tier: Support
Support is a specialized option in Bloons TD 6.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Banana Farm | The income tower. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Cash income and the Banana Farm | Cash comes from popping and from round end bonuses, and the Banana Farm converts early spending into a much bigger late defence. |
How to Play Support
Support focuses on a balanced approach to content.
Why this build works: This one leans on Cash income and the Banana Farm rather than raw numbers, and Banana Farm is what makes that trade pay off. See our weapons guide for detailed equipment breakdowns.
Pros:
- Strong in group/team content
- Straightforward gearing path
- Excels in its niche
Cons:
- Weaker solo performance
- Requires deep game knowledge
A-Tier: Heroes
Heroes is a specialized option in Bloons TD 6.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Super Monkey | Expensive and worth it. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | CHIMPS ruleset | CHIMPS stands for no Continues, no Hearts lost, no Income, no Monkey Knowledge, no Powers and no Selling. |
How to Play Heroes
Heroes focuses on a balanced approach to content.
Why this build works: Super Monkey and CHIMPS ruleset pull in the same direction here, which separates this from the safer picks above. See our weapons guide for detailed equipment breakdowns.
Pros:
- Unique, rewarding playstyle
- Straightforward gearing path
- Excels in its niche
Cons:
- High skill floor, punishing when misplayed
- Requires deep game knowledge
Build Progression Path
- Start with Military: the most forgiving option for learning the game
- Transition to Primary once you understand core mechanics and have access to Dart Monkey
- Keep a Magic setup for content that keeps killing you
- Try Heroes for a fresh experience once you've mastered the basics
Follow our walkthrough for the optimal progression path through each area.
Gearing Tips
- Invest in your primary equipment first, since it gives the biggest power spike. See our weapons guide for rankings.
- Buy the two crosspath tiers before the tier 4 upgrade in most cases. A 2-0-4 Ninja out damages a 0-0-4 Ninja by a wide margin because pierce and attack speed multiply the base attack rather than adding to it.
- Sort out camo detection before camo rounds arrive rather than during them. A Monkey Village with Radar Scanner at path 2 tier 2 covers every tower in its radius, and Ninja Monkeys and Sniper Monkeys with the right upgrades see camo without help.
- Don't spread upgrade resources across multiple builds until endgame
