To stop Ghost Bloons from bypassing your defenses in Bloons Blitz, place detection units in central locations along the track and align your hero active reveal abilities with your high-damage kill zones. Ghost Bloons ignore standard line-of-sight vision, requiring targeted stealth-detection upgrades or active hero skills before primary damage towers can strike them.
Setting Up Detection Coverage
Ghost Bloons move past standard line-of-sight defenses completely undetected. Relying purely on raw damage towers causes stealth waves to push through your perimeter without taking damage.
To build an effective stealth counter:
- Position units centrally: Place detection-capable towers where their coverage overlaps with primary damage units.
- Prioritize low-tier reveals: Upgrade multiple low-cost detection units across the map rather than investing heavily in a single expensive tower that can leave blind spots.
- Establish coverage early: Purchase detection upgrades before mid-wave density spikes so stealth units are stripped of their concealment as soon as they enter range.
Hero Ability Timing for Ghost Waves
Hero abilities act as a key emergency response when Ghost Bloons threaten to overwhelm your passive detection network. Because active reveal skills operate on cooldowns, precise timing determines whether your primary towers clear the wave.
Use these guidelines when triggering hero abilities:
- Sync with kill zones: Activate reveal skills right as Ghost Bloons enter the firing radius of your highest-DPS towers.
- Save skills for stealth waves: Avoid spending reveal abilities on standard bloon waves so cooldowns remain ready for incoming stealth segments.
- Watch wave indicators: Track incoming spawn density on the enemy bar to trigger skills before stealth units slip past your front line.
Balancing Economy and Tower Space
Spending gold on detection reduces the capital available for pure damage upgrades. Maintaining line integrity requires balancing stealth coverage with offensive output and map footprint.
| Strategy Focus | Priority Action | Risk to Avoid |
|---|---|---|
| Gold Allocation | Invest in income generators early to offset detection upgrade costs | Over-spending on raw damage towers that cannot see target bloons |
| Map Footprint | Spread low-cost detection units across open maps | Over-crowding placement slots on tight maps with redundant reveal units |
| Tight Layouts | Rely on timed hero reveal abilities when tower space is strictly limited | Neglecting raw DPS while attempting to achieve 100% passive detection |
If Ghost Bloons are consistently revealed but reach the exit, shift spending back into pure damage upgrades. If high-damage towers remain idle while enemies pass, expand your detection network immediately.

Can you add more details about early game in a future update?
This helped me understand early game much better.
I tried this today and it worked better than my old setup.
This guide answered the exact question I had.
