Clash of Clans is gearing up for a major event this Summer, and it is going to be a blockbuster for everyone involved. This July 2025, we are seeing the launch of a new event called Summer Jam 2025, a fresh twist on the beloved Hammer Jam event in Clash of Clans.
Running from July 3rd to August 8th, 2025, this five-week celebration is split into four phases over the period. These will be themed bootcamps, each focused on a specific resource type.

During these periods, you can take advantage of 25% reduced upgrade times and a massive +100% boost to both the speed and capacity of collectors in the home village. It is important to note that this is excluding walls and temporary upgrades.
Each bootcamp rolls out a new focus. From July 3rd to 13th, Gold upgrades and Gold Mines get the spotlight. After that, from July 13th to 22nd, the bonus shifts to Elixir upgrades and Elixir Collectors. Then, from July 22nd to August 1st, it is all about Dark Elixir and its drills.
Finally, the big finale runs from August 1st to 8th, where all collectors receive the +100% boost and every upgrade type gets the 25% time discount. A complete table for the same is given below for your convenience.
| Bootcamp | Dates | Upgrade Discount | Resource Boost | Affected Resources |
|---|---|---|---|---|
| Gold Bootcamp | July 3 – July 13 | 25% upgrade time for Gold upgrades & Forge | +100% Gold Mine speed & capacity | Gold |
| Elixir Bootcamp | July 13 – July 22 | 25% upgrade time for Elixir upgrades & Forge | +100% Elixir Collector speed & capacity | Elixir |
| Dark Elixir Bootcamp | July 22 – August 1 | 25% upgrade time for Dark Elixir upgrades & Forge | +100% Dark Elixir Drill speed & capacity | Dark Elixir |

How to maximise the Summer Jam event in Clash of Clans
Summer Jam is a great time to push your village forward, but the real key lies in timing. Each bootcamp brings its unique boosts, so try to plan your upgrades around these phases. During the Gold Bootcamp, prioritize gold-based upgrades like defenses and buildings.
Just be sure to keep your builders busy and queue upgrades before the discount period ends. Elixir Bootcamp is your window to upgrade storages, barracks, army camps, and lab troops. Make sure your laboratory lines up with the transition so that you’re not stuck upgrading gold-based buildings during the elixir-focused week. Same goes for the Dark Elixir.
The final stretch is where it all comes together. All boosts and discounts are active, so this is the best time to use your magic items like Builder Potions and Research Potions to free up builders and lab space.
Even if you start an upgrade a few minutes before the event ends (8:00 AM UTC on August 8), the discount still applies. Keep your lab and builders active and upgrade as much as possible before the bonuses vanish.
