Hammer Jam Kicks Off: Enjoy 50% Upgrade Discounts and Massive Loot Bonuses in November's Clash Events
November 1, 2025
Week 3 centers on the Mini Medal Event beginning mid-November, offering additional medals through challenges.
Kick off Hammer Jam as the main event running from early November through mid-month, with a parallel Clan War League delivering loot-focused competition for clans.
Clan War League spans the first half of November, featuring consecutive-victory battles and expected to launch alongside Hammer Jam, plus tease of a new Community Event increasing loot opportunities.
Maximize resource gains by keeping builders free, timing double-value potions for efficiency, and upgrading resource collectors to the highest levels.
During the event, store and use resource boosts and Gems to secure items like potions from the Clan War League shop and other in-game shops.
A telescope-themed Challenge Level image hints at a new decorative or challenge-related feature, though details are not yet disclosed.
Week 2 brings a 4x Star Bonus, granting four times the usual loot bonus for successful attacks.
Prioritize shorter upgrades early to maximize discounts and complete multiple upgrades quickly, saving longer upgrades for later.
Use event-earned extra resources to upgrade defenses and keep the Laboratory running, saving Books of Building or Everything for post-Hammer Jam upgrades toward Town Hall 18.
Consult GamingonPhone’s linked resources for broader context on rewards, challenges, and strategic guides.
Stay updated through GamingonPhone’s WhatsApp, Telegram, Discord, and social channels for rapid news.
Expect a 2x increase in resource production and storage during the event to streamline progress.
During Hammer Jam, expect a 50% cut to upgrade costs and a 50% reduction in upgrade times to accelerate progression.
Stay mindful of Town Hall 18’s upcoming launch and plan upgrades to be ready when it goes live.
