Wait... What Even Is Hammer Jam in Clash of Clans?

Okay chief,

So imagine Clash just dropped a “Black Friday sale,” but for literally everything in your village. That’s Hammer Jam.

Every upgrade like walls, troops, defenses gets a massive 50% discount in both time and cost. Yeah. Half.

It’s basically Supercell saying, “Here, go nuts before the new Town Hall Update drops.”

The event usually lasts 15 days, right before a new Town Hall release. And since Town Hall 18 is probably landing around mid-November, Hammer Jam should kick off right after the World Championship (October 31–Nov 2).

So yeah, mark your calendars. Early November’s about to get wild.

🧠 The Smart Player’s Shopping Spree

You don’t just want to upgrade randomly like a goblin in a gold mine. There’s a strategy here.
Here’s how to squeeze every drop of value out of Hammer Jam:

1. Save your Clan War League medals — and use them to buy Builder Potions, not hammers. One builder potion = 54 hours saved (if you’ve got six builders). Do the math. It’s way better value.
   Can't triple? Use these armies (Army links included)

2. Stack boosts. Hammer Jam’s 50% + Gold Pass’s 20% = a total of 60% faster upgrades. That’s not “math magic,” that’s just beautiful, game-breaking math.
   Use code BLUE for any purchases in Shop.

3. Double down with potions — Research and Pet Potions are worth twice as much during the event since upgrade times are halved. Honestly, it’s the best return on your magic items all year.

And yeah, if Goblin Workers are active, things get even crazier. Stack that too.

❌ The WORST Mistakes Players Make During Hammer Jam ▶️

Some of us (we’re not naming names) get a little too excited and waste magic items during Hammer Jam.

Here’s the thing: DON'T USE Books or Hammers now. Their value is sliced in half because upgrades are already cheaper. Save them for after the event when prices go back up.
During Hammer Jam, Builder Potions are your best friend. Like, BFF level.

Also, pro tip: start your longest upgrades on the last day of Hammer Jam. That way, they keep their reduced time even after the event ends. It’s like sneaking an extra dessert after dinner.

💰 Farming During Hammer Jam (aka the Loot Olympics)

You’ll need mountains of resources, obviously. So let’s talk armies:

• Sneaky Goblins if you’re all about pure loot efficiency.

• Mass Baby Dragons if you want chill farming.

• E-Drags or regular Dragons with Lightning if you’re lazy but still want solid gains.

Oh, and if you still don’t have your sixth builder… do it. Seriously. Six builders change everything. Think of it as unlocking Ultra Instinct for your base.

Rushing Smart (Not Reckless)

You don’t need to max everything. Nobody’s judging if your traps or spells are one level behind. Focus on what really matters—your attack comps, heroes, and army camps.
Upgrade smart, not sentimental. Walls can cry later.

⚡ Quick Math, Big Gains

Let’s do a fun brain flex:

• Builder Potion = 9 hours × 6 builders = 54 hours saved

• 4 potions = 216 hours (~9 days) saved

• Add Hammer Jam = value doubled → 18 days worth of upgrades for the cost of 4 potions.

Yeah, go ahead, tell your clanmates. You’ll sound like a Clash economist.

Hammer Jam is that rare, glorious time when grinding actually feels rewarding. Stock up, stack boosts, and time your upgrades like a pro.

So… you ready to max before Town Hall 18 drops? Because honestly, we’re not. But we’re doing it anyway.
