Build An Ant Empire
Build An Ant Empire Halloween Event: Start Time and Countdown
Build An Ant Empire is heading into its biggest stretch of the season. A dedicated Halloween Event is scheduled to open on October 28, bringing pumpkin chests, a candy-powered summon system with a pity mechanic, and a co-op boss dungeon. It is already the most-anticipated item on the game’s calendar, with about 9,400 players flagging interest before it goes live.
Two updates are live in the meantime. The Time Wrap Event adds a limited ant along with new pet, mutation, and item drops and runs through October 23, while a smaller Auto Roll update — which also opened Halloween pre-registration — stays up through October 30. The colony-builder from Insect Kingdom studio is drawing about 8,900 players at the moment and has passed about 27,000,000 lifetime visits, with about 470,000 favorites.
Below is the live schedule, followed by a breakdown of each event, its window in Eastern Time, and how it fits the studio’s recent update rhythm. Last updated October 22.

Current and upcoming events
Halloween Event (starts October 28)
The Halloween Event is the marquee item here. It opens on October 28 at 10:00 AM ET (7:00 AM PT; 2:00 PM GMT) and runs through November 13, ending at 5:00 AM ET. The developer’s notes describe a full seasonal package: Pumpkin Chests that pay out Candy, Ghostfire, and event items; a Flying Broom you equip in the event area to take to the air; and a Candy Summon shop where spent Candy rolls for limited units, pets, mutations, and mounts — including rewards brought back from earlier events — with published rates and a pity system. There is also a Ghostfire Dungeon, a co-op fight unlocked once players pool 40 Ghostfire, a Castle Trick-or-Treat activity, and a Mutation Extraction cauldron that converts a mutated unit into a matching potion. Interest is the highest on the calendar, at about 9,400 and still climbing.
Time Wrap Event (live through October 23)
This event is live now and ends October 23 at 4:00 AM ET, so there is roughly about a day left left. It centers on collecting event coins to spin a wheel for prizes, and it introduces a new limited ant alongside a limited pet, a limited mutation, and a limited item. Interest sits at about 3,700.
Auto Roll update (live through October 30)
Live through October 30 at 4:00 AM ET, this update is lighter on content but notable for two quality-of-life additions — auto roll and auto buy — and for opening pre-registration for the Halloween Event. Its interest count is modest next to the seasonal event, with about 630 interested.
Recently ended: the Eternal rarity update (October 10–16)
The previous update ran October 10 to October 16 and added a new Eternal rarity, three new ants, and the ability to view pet information from the inventory. It drew a few thousand interested players before wrapping.
Update cadence
Insect Kingdom studio has been shipping updates on a roughly weekly rhythm through the fall, with drops landing around October 10, October 15, and October 21. Between the larger seasonal events, players can reasonably expect new content about once a week.
