Getting an extra Builder in Clash of Clans can completely change the way you progress in the game. Normally, players only have five Builders to upgrade buildings, walls, heroes, and defenses. Because of that, reaching higher Town Hall levels can take a very long time.
To solve this issue, Supercell introduced the sixth Builder through the Builder Base update. This special Builder is called B.O.B., and unlike normal Builders, you cannot buy him with Gems.
Players must complete several important tasks inside Builder Base to unlock him permanently.
What Is The 6th Builder In Clash Of Clans?
The sixth Builder is a robot helper called B.O.B. He works just like every other Builder in the game and stays permanently in your Home Village once unlocked.
Before this update, players had to move the Master Builder between the Home Village and Builder Base. That system was slow and annoying for many players.
Now, after unlocking the B.O.B Hut, the Master Builder stays in Builder Base while B.O.B handles upgrades in the main village.
This extra Builder becomes extremely valuable in the late game because upgrade times become much longer at higher Town Hall levels.
Why The 6th Builder Is So Important
At higher Town Hall levels, some upgrades can take more than two weeks to finish. Having one more Builder means you can work on extra upgrades at the same time.
This gives players many advantages:
- Faster building upgrades
- More wall upgrades daily
- Easier Hero leveling
- Better progress during events
- Less waiting time overall
Many experienced players believe the sixth Builder can reduce total village progression time by several months.
Because of this, unlocking B.O.B is considered one of the best long-term goals in Clash of Clans.
How To Unlock The Clash Of Clans 6th Builder
To unlock B.O.B, players first need to reach Builder Hall 9.
After reaching Builder Hall 9, you can access the B.O.B Control Hut. Then, you must complete four different requirements.
1. Gear Up Three Buildings
You need to use the Gear Up feature on these Home Village defenses:
- Cannon
- Archer Tower
- Mortar
These upgrades connect your Builder Base progress with the Home Village.
2. Upgrade One Builder Base Troop To Level 18
Any Builder Base troop can be upgraded to level 18.
Most players prefer:
- Cannon Cart
- Baby Dragon
Both troops are very useful for Builder Base attacks.
3. Upgrade One Defense To Level 9
You must upgrade one Builder Base defense to level 9.
The Multi Mortar is usually the best choice because it is already needed for one of the Gear Up tasks.
4. Reach Combined Hero Levels Of 45
This is often the hardest requirement.
Your Battle Machine and Battle Copter levels combined must reach 45 total levels.
Example:
- Battle Machine Level 25
- Battle Copter Level 20
This requirement takes patience because Hero upgrades in Builder Base can become expensive.
Best Tips To Unlock B.O.B Faster
Here are some useful tips to speed up the process:
- Focus on Builder Hall progression early
- Save resources mainly for Hero upgrades
- Upgrade Cannon Cart first for easier attacks
- Always keep both Builders active
- Complete Clan Games for extra magic items
- Use Clock Tower boosts daily
Smart resource management can help unlock the sixth Builder much faster than expected.
B.O.B. is one of the best rewards in the game
The sixth Builder is more than just an extra worker. It is a major progression boost that helps players improve their villages much faster.
Even though unlocking B.O.B takes time and effort, the reward is completely worth it in the long run. Once unlocked, players can enjoy smoother upgrades and faster progress across every Town Hall level.
