Clash of Clans opens Builder Base Bonanza with cheaper upgrades and faster timers

Clash of Clans is giving neglected Builder Bases a rare moment in the spotlight. Builder Base Bonanza begins today and runs until 31 May, celebrating nine years since the second village first arrived. Supercell's official May schedule confirms a 50% discount on Builder Base upgrade costs and timers, plus 4x Star Bonuses and Builder Base tasks. That is not just a cosmetic event.

For players who have ignored Builder Base because progress felt slow or detached from the main village, this is one of the best upgrade windows of the month. It also arrives right after the Super Witch Mini Spotlight and alongside the wider Skeleton Kingdom season, keeping Clash's May calendar unusually dense. The smartest move is simple: prioritise expensive Builder Base upgrades while the discount is active instead of burning resources outside the event window.
