Bloons TD 6 Social Season 1 Phase 2 Guide – Challenge 1 & 2

If you’re working through the latest Social Season challenges in Bloons TD 6, Phase 2 is actually much easier than it first looks. At first glance, seeing requirements like:

  • 15 Mermonkey clears
  • 10 Desperado clears
  • 7 Engineer clears
  • 200 obstacle removals

sounds painfully grindy.

But the good news is you can combine Challenge 1 and Challenge 2 progress together and finish everything way faster than expected.

This guide covers:

  • the fastest maps to use
  • easiest hero setups
  • upgrade paths
  • how to combine obstacle removals efficiently
  • which rounds need abilities
  • the least annoying way to grind the entire event

Honestly, after figuring out the best maps, most runs become almost fully AFK.

Bloons TD 6 Social Season 1 Phase 2 Guide – Challenge 1 & 2

Challenge 1 requires clearing maps using:

  • only Dart Monkeys + Hero
  • only Buccaneers + Hero
  • only Engineers + Hero
  • only Desperados + Hero
  • only Mermonkeys + Hero

Meanwhile Challenge 2 requires removing:

  • 200 obstacles

The smart part is that Buccaneer runs on High Finance let you farm obstacle removals while progressing tower clears at the same time.

That saves a ridiculous amount of grinding later.

Best General Strategy

For most categories:

  • play Easy difficulty
  • use short maps
  • stick to cheap upgrade paths
  • let your hero carry early rounds

The majority of these setups revolve around:

  • Sauda
  • Gwendolin

because they can almost solo early-game waves while your towers scale.

Dart Monkey + Hero Strategy

Best Map

In The Loop

Difficulty

Easy

This is probably the easiest setup of the entire challenge set.

Recommended Build Order

Step 1

Place:

  • Sauda

She carries the early game almost by herself here.

Step 2

Place left Dart Monkey:

  • 0-2-0
  • eventually upgrade to 4-2-0

Set targeting to:
Strong

This handles stronger bloons extremely consistently.

Step 3

Place right Dart Monkey:

  • 0-2-0
  • upgrade to 0-2-4

At this point the map basically clears itself.

Buccaneer + Hero Strategy (Best Obstacle Farming Method)

Best Map

High Finance

Difficulty

Easy

This is the most important setup because it also farms obstacle removals for Challenge 2.

Recommended Build Order

Step 1

Place:

  • Sauda

Step 2

Place first Buccaneer:

  • 0-0-2
  • upgrade to 0-3-2

Set targeting to:
Strong

Step 3

Place second Buccaneer:

  • 0-0-2
  • upgrade to 0-3-2

Also target:
Strong

How to Farm Obstacle Removals Fast

Once your defense is stable:

Spend all remaining money upgrading buildings around the map.

Every building upgrade counts toward:
Remove an obstacle

You can usually buy:

  • around 14 obstacle upgrades per run

Since the challenge needs:

  • 5 Buccaneer clears

you’ll naturally end up with roughly:

  • 70 obstacle removals

just from these runs alone.

This massively cuts down future grinding.

Important Round 40 Tip

Use:

  • Sauda’s leap ability

on Round 40 for safer cleanup.

Without it, the MOAB can occasionally leak depending on timing.

Engineer + Hero Strategy

Best Map

In The Loop

Difficulty

Easy

Engineers are honestly smoother than expected for this challenge.

Recommended Build Order

Step 1

Place:

  • Sauda

Step 2

First Engineer:

  • 0-2-0
  • upgrade into 0-2-4

Step 3

Second Engineer:

  • 0-0-2
  • upgrade into 0-3-2

Important Placement Tip

Place:

  • Cleansing Foam

directly underneath:

  • the Bloon Trap

This helps maximize trap value and keeps cleanup consistent.

Round 40 Tip

Again:

  • use Sauda’s ability

for safer MOAB damage.

Desperado + Hero Strategy

Best Map

In The Loop

Difficulty

Easy

This one is surprisingly simple once upgrades come online.

Recommended Build Order

Step 1

Place:

  • Gwendolin

Set targeting:
Strong

Step 2

Bottom Desperado:

  • 0-2-0
  • upgrade into 0-2-3

Step 3

Top Desperado:

  • 0-2-0
  • upgrade into 4-2-0

This combination handles grouped bloons and stronger targets pretty comfortably.

Mermonkey + Hero Strategy

Best Map

Spa Pits

Difficulty

Easy

This setup is slightly slower than the others but still very manageable.

Recommended Build Order

Step 1

Place:

  • Gwendolin

Set targeting:
Strong

Step 2

Left Mermonkey:

  • 0-0-2
  • upgrade into 4-0-2

Step 3

Right Mermonkey:

  • 0-0-2
  • upgrade into 0-3-2

Once both upgrades are active, the map becomes very stable.

Fastest Way to Finish All Challenges

If your goal is speed rather than variety, this route feels the most efficient:

First

Complete:

  • all Buccaneer runs

while farming obstacle removals.

Second

Finish:

  • Dart Monkey
  • Engineer
  • Desperado

on In The Loop since it’s fast and easy to restart.

Third

Finish:

  • Mermonkey runs

last since they take slightly longer overall.

Best Heroes for These Challenges

Sauda

Best for:

  • short maps
  • early carry
  • MOAB cleanup

She makes Easy difficulty runs extremely relaxed.

Gwendolin

Best for:

  • grouped bloons
  • fire spread
  • support damage

Especially effective during Desperado and Mermonkey clears.
