Clash of Clans Hammer Jam Event: How It Works & When It Happens

by

Hammer Jam is a highly anticipated event in Clash of Clans. Players get excited about it because it lets them quickly build and upgrade their buildings.

The Hammer Jam event is usually a strong indicator that Supercell is planning to release a new Town Hall level soon. This has been the case with the last six major updates – Town Halls 12 through 17 – each of which was released shortly after the event ended.

Now, let’s take a closer look at how the Hammer Jam event works in Clash of Clans.

How the Hammer Jam Event Works in Clash of Clans

The Hammer Jam event offers players a 50% discount on all building and upgrade costs in their home village. These improvements also happen 50% faster. However, these benefits don’t apply to the Builder Base.

As a long-time player, I always get excited for Hammer Jam! It’s basically a lifesaver when you’re trying to build up your village, letting you save a ton of resources. Honestly, it’s especially helpful if you’re a more advanced player – those upgrades get seriously expensive at higher Town Hall levels, and this event makes a huge difference!

When Is The Next Hammer Jam Event?

The Hammer Jam event in Clash of Clans typically happens right before a new Town Hall is released. Since new Town Halls only come out about once a year, the event is quite rare, which makes it highly anticipated by players.

Hammer Jam is here with great discounts! Don’t forget to upgrade your Walls – are they still lagging behind at level 5? #hammerjam

Once the current update is finished, players will be able to unlock Town Hall 18, which will include new buildings, improvements, troops, spells, features, and other exciting additions.
