Clash of Clans: How To Unlock 6th Builder

Unlocking the sixth builder in Clash of Clans is one of the biggest goals for players who want to speed up their progress and upgrades. With six builders working at the same time, you can drastically cut down the waiting time for buildings, defenses, and upgrades, making it a game-changing advantage. However, unlocking the sixth builder isn’t as simple as just buying it — it requires completing specific tasks and progressing in Builder Base. In this guide, we’ll break down everything you need to know about how to unlock the sixth builder, the steps involved, and tips to get it as fast as possible.

How To Unlock The 6th Builder in Clash of Clans

To unlock the 6th Builder in Clash of Clans, you’ll need to construct and upgrade the B.O.B Control in your Builder Base. This special building becomes available once you reach Builder Hall level 9 and costs 1,000,000 Gold to build. However, unlocking B.O.B. as a usable builder in your Home Village requires upgrading the B.O.B Control to level 5 by completing several key requirements.

First, you’ll need to gear up three Home Village defenses — the Cannon, Archer Tower, and Mortar — which requires specific upgrade levels in both your Home Village and Builder Base. Next, you must upgrade any troop to level 18 in the Star Laboratory (level 9 required), with troops like Baby Dragon or Super P.E.K.K.A. being popular choices. You’ll also need to upgrade a Builder Base defense to level 9, with the Multi Mortar being the most efficient option. Finally, you must reach a combined level of 45 between the Battle Machine and Battle Copter; this can be done by pushing your Battle Machine to level 25 and leveling the Battle Copter to 20.

Once all these requirements are met, you can fully upgrade the B.O.B Control to level 5, unlocking B.O.B’s Hut. Place the hut in your Home Village, and you’ll officially have your 6th Builder — giving you a huge advantage in speeding up upgrades and base progression.

Conclusion

Unlocking the 6th Builder in Clash of Clans is no easy task, but it’s one of the most rewarding upgrades you can achieve. By focusing on gearing up defenses, pushing troop and hero levels, and investing in your Builder Base, you’ll eventually meet all the requirements to max out the B.O.B Control. While it takes patience and planning, the payoff of adding an extra builder to your Home Village is massive — giving you faster upgrades, smoother progress, and a long-term edge over other players. If you’re aiming to take your base to the next level, securing that 6th Builder is absolutely worth the grind.
