In DON’T LET HIM IN, the threat waiting outside the door keeps changing, and the New Monster event is how it changes. Each drop adds a brand-new antagonist to face — a fresh enemy with its own look and its own way of trying to get past your defenses. With about 4,000 players in the game right now and more than about 23,000,000 visits logged so far, every new monster arrives in front of a large, active crowd.

New Monster isn’t a one-time stunt. dilly dally games brings a new creature around on a roughly weekly schedule — it has run 3 times already — so there is almost always another one on the way. The next appearance and the usual times it tends to go live are on the card below.

How often New Monster runs

New monsters land on a weekly cadence — close to once a week, give or take a day. The next one is expected around Thursday, October 22 at 12:41 AM ET; that date is our best estimate from the event’s usual rhythm, and we confirm it once dilly dally games posts the exact timing.

Across its runs, New Monster has tended to appear in three recurring Eastern-time windows rather than at a single moment. The staggered times work well for a global audience: whichever window hits, players outside North America get a reasonable shot at being online when the new monster first shows up. The three windows, with rough conversions for the major regions, line up like this:

Window (ET)UKCentral EuropeIndiaJapanAustralia (AEDT)
Thursday, 3:05 PM8:05 PM9:05 PM12:35 AM (Fri)4:05 AM (Fri)6:05 AM (Fri)

Saturday, 2:20 PM7:20 PM8:20 PM11:50 PM3:20 AM (Sun)5:20 AM (Sun)
Clocks shift by an hour in regions that observe daylight saving, so check against Eastern time if you are near a changeover.

What happens in a New Monster drop

Each New Monster update centers on one thing: a new enemy to survive. A typical drop brings:

  • A new monster with its own appearance, sounds, and tactics for breaking in.
  • Fresh behavior to learn — the counters that worked on the last threat rarely carry over cleanly.
  • A reason to jump back in, since the newest monster is the one everyone is trying first.

Because the headline is the creature itself, the real draw is seeing how it plays and working out how to keep it out before it beats you.

Tips for catching New Monster

  • Pick the window that suits you. The Saturday afternoon ET slot is the friendliest for the Americas and Europe, while the Friday early-morning ET slot lands at daytime hours across Asia and Australia.
  • To be there at the start, set a reminder for the next window — the next time and the usual windows are on the card above.
  • Miss it and nothing is lost: a new monster comes around again the following cycle, and the one you missed stays in the game.

Where New Monster fits in DON’T LET HIM IN
