BTD6 beginner guide
How to Pop Camo, Lead, Purple and DDT Bloons in BTD6
Most leaks are not random. They happen because the defense solved damage but not visibility, visibility but not damage type, or early bloons but not their late-game combinations.

What is the difference between camo detection and damage type in BTD6?
In BTD6, camo detection and damage type are separate checks. Camo detection asks whether a tower is allowed to target the bloon at all; a tower without camo vision may ignore the target even if its attack would otherwise pop it. Damage type asks whether the attack can harm the bloon after it is targeted. Lead bloons resist many sharp attacks, while purple bloons resist energy, fire, and plasma style damage. Camo lead combines both checks, which is why a defense can see camo but still fail to pop lead, or pop lead but never attack the camo version. DDTs add another layer because they combine camo, lead, black properties, high speed, and MOAB-class health. The safest beginner habit is to ask what the leak tests before buying more damage. That diagnosis usually saves more cash than buying another random upgrade.
Choose the bloon that leaks
I can pop normal bloons, but camo slips past everything.
BTD6 counter check
Camo Bloons
Camo is mostly a targeting problem. A tower that cannot see camo will ignore it even if that tower has enough damage.
Add direct camo detection early, or remove camo with support before your main damage zone.Cheap counters
Sees camo by default and handles the first camo checks cleanly.
Enhanced Eyesight is a cheap early cleanup answer.
Night Vision Goggles works well on open lanes.
Monkey Sense fits builds already using magic damage.
Reliable options
Shares camo detection with nearby main damage towers.
Strips camo before the bloons reach your damage zone on water maps.
Levels into global camo detection for the whole defense.
Support logic
Put camo support before the strongest damage cluster, not after it.
Helpful when a camo-capable tower keeps wasting shots on normal bloons.
Camo lead or camo purple also needs the right damage type.
Common mistakes
- Buying more damage while no tower can actually target camo.
- Putting Radar Scanner outside the range of the towers that need it.
- Forgetting that later camo waves can also be lead, purple, ceramic, or DDT.
Quick counter table
| Problem | What it tests | Beginner-friendly answer |
|---|---|---|
| Camo | Needs camo detection, Can combine with other properties | Add direct camo detection early, or remove camo with support before your main damage zone. |
| Lead | Immune to sharp-style damage, Often punishes all-sharp starts | Add one lead-popping source before Round 28, then make sure your later damage still covers lead. |
| Purple | Immune to energy, Immune to fire, Immune to plasma | Use sharp, explosive, bullet, or other non-purple-blocked damage before leaning on fire and plasma. |
| Camo Lead | Needs camo detection, Needs lead-popping damage | Use a direct camo-lead tower, or pair camo reveal with lead-popping damage before Round 59. |
| DDT | MOAB-class, Camo, Lead, Black, Very fast | Prepare camo detection, lead-capable damage, black-compatible damage, and enough MOAB control before Round 90. |
Targeting
Camo is about seeing the bloon
A tower without camo detection may have enough damage and still do nothing. Use direct camo towers, Radar Scanner, or decamo before your strongest damage zone.
Damage type
Lead and purple ask different questions
Lead punishes many sharp attacks. Purple punishes energy, fire, and plasma. A mixed setup is safer than one expensive tower line with a blind spot.
Combination
Camo lead needs both checks
Round 59 catches players who bought only camo detection or only lead damage. The same tower or support setup needs to cover both jobs.
Late game
DDTs are not just faster leads
DDTs combine camo, lead, black properties, MOAB-class health, and speed. Prepare before Round 90 with coverage, control, and enough MOAB damage.
Common beginner mistakes
- Buying more damage when the real issue is camo detection.
- Buying camo detection on a tower that still cannot damage lead.
- Relying on fire, energy, or plasma as the only cleanup into purple waves.
- Waiting until Round 90 to think about DDTs.
- Putting support towers after the track section where the leak actually happens.

FAQ
Can one BTD6 tower pop every special bloon?
Some higher-tier towers get broad coverage, but beginners should think in checks: camo detection, lead damage, purple-safe damage, and enough speed or MOAB damage for DDTs.
Is camo the same as an immunity?
No. Camo is mainly a targeting property. A tower without camo detection usually cannot attack it, even if that tower has the right damage type.
Why does Monkey Intelligence Bureau help so much?
Monkey Intelligence Bureau simplifies many damage-type problems for towers in range, but it does not replace placement, camo coverage, or enough damage.
