Clash of Clans Builder Base Bonanza Event Guide: Here's How to Get the Rewards

Supercell is celebrating the ninth anniversary of the Builder Base in Clash of Clans with an event offering players the chance to accelerate their upgrades. The Clash of Clans Builder Base Bonanza Event has started today and will be running until May 31, 2026.

The event offers multiple Magic Items and Bonuses, including some Hammer Jam-esque rewards, but for the Builder Base! Let's take a detailed look at the Clash of Clans event and how to claim all the rewards!

Clash of Clans Builder Base Bonanza Event Overview

Players can take advantage of straight 50% off cuts in build timespan and upgrade costs for all troops, defenses, and structures in the Builder Village during this event. This is the ideal time to work on expensive upgrades in the Builder Base, whether your goal is to unlock the Clash of Clans 6th Builder or to fully upgrade Builder Hall 10 before the new Builder Hall level is potentially announced!

The timing of the Clash of Clans Builder Base Bonanza Event is ideal for players looking to unlock B.O.B. He is the sought-after sixth builder for the Home Village that can help you accelerate your main village upgrades. To unlock B.O.B, villagers must reach certain milestones in their Home Village, including upgrading the heroes to a combined level 45, upgrading at least one army troop to level 18, and equipping three defenses in the main village.

Clash of Clans Builder Base 4x Star Bonus Event

The Clash of Clans Builder Base 4x Star Bonus will be active for the whole length of the event, allowing you to focus on upgrading your Builder Base, while keeping your Builder Gold and Elixir storage full.

Players just need to make their daily Builder Base attacks and earn stars to benefit from this resource boost. Don't forget to grind out your daily attacks, as you will be four times the regular daily bonus, allowing you to keep your builders occupied without having to spend hours grinding for loot.

Don't forget to utilise the extra loot and upgrade your Builder Base walls during the Clash of Clans Builder Base 4x Star Bonus Event. Additionally, while this event focuses on the Builder Base, play the ongoing Clash of Clans Clash vs Skeletons Event to earn rewards for your Home Village!

Clash of Clans Star Chaser: Rune

Apart from the 4x Star Bonus, the event includes a Progress Milestone track that tracks your progress throughout the event. The Clash of Clans Star Chaser: Rune Milestone reward players with 400 XP and the Rune of Builder Elixir!

During the CoC Builder Base Bonanza event, you will be able to earn 3x Builder Star Jars, 3x Clock Tower Potions, and a free Rune of Builder Elixir by winning stars in your Builder Base battles.

It's simple and easy to get these rewards by just getting high-percentage, three-star, or six-stars in your daily attacks and progress in the Milestone Path. The Builder Base Bonanza Event offers the best value phase the base has seen in years. With half-priced building upgrades, quicker timers, and a constant stream of rewarding magical items, players can easily upgrade their Builder Bases in no time!
