Introduction
The wait is over Hammer Jam 2025 has arrived in Clash of Clans, signaling the start of one of the most exciting times of the year. This limited-time event not only gives players massive discounts on upgrades but also sets the stage for the long-awaited Town Hall 18 update. From 50 % building reductions to new hero skins, sceneries, and special in-game events, here’s everything you need to know to prepare your village for the next big chapter.
🛠️ What is Hammer Jam 2025?
Hammer Jam is a global event that appears before the release of a new Town Hall level. During the event, all home-village upgrades cost and take 50 % less—including buildings, troops, heroes, pets, and walls.
This gives players the best opportunity to strengthen their base and catch up before the upcoming Town Hall 18 update.
Excluded: temporary items such as seasonal troops and crafted defenses are not discounted.

2. Farm Smart and Fast

- Resource Collectors produce and store double loot, making bases richer targets.
- Use battle mode freely no trophies lost, only loot gained.
3. Manage Magic Items and Medals
- Builder Potions > Research Potions > Hammers > Books in terms of value during this event.
- CWL medals and raid medals can be exchanged for potions or loot.
- Save a few Books of Heroes and Books of Building if you plan to rush into Town Hall 18 right after the update.
4. Stack Your Bonuses

5. Utilize the Goblin Builder and Researcher

🌌 Extra Ore and Meteor Events
Throughout Hammer Jam 2025, meteors crash onto your village. Removing them yields different types of Ore – Shiny, Glowy, and Starry.
Players who collect Ore can use it for hero equipment and upgrades. Collectors may also choose to keep one of each as limited-edition obstacles.
🏰 Connection to Town Hall 18
Hammer Jam traditionally leads directly into the next Town Hall release and 2025 is no different. The telescope event ending on November 17 strongly hints that the Town Hall 18 update will arrive soon after.
Players should:
- Finish critical upgrades before mid-November.
- Stockpile Builder Potions, Books, and Ore.
- Keep at least one builder free to start Town Hall 18 immediately when the update drops.
While previous updates introduced major cost reductions alongside a new Town Hall, this time Supercell already provided big discounts in October 2025 so no additional reductions are expected beyond Hammer Jam.
⚔️ Final Thoughts
Hammer Jam 2025 is the best time of the year to supercharge your progress in Clash of Clans. With half-price upgrades, boosted loot, and exclusive Wasteland-themed cosmetics, it’s the perfect chance to maximize your base before the arrival of Town Hall 18.
Stay active, plan your builders wisely, and don’t let the discount go to waste—once it’s over, the next chapter of Clash of Clans begins.
