+1 Drain Water for Treasure World 4: Next Expansion Countdown
In +1 Drain Water for Treasure, players pump lakes dry to uncover the loot buried beneath them, and the map keeps growing: a fresh World Expansion arrives on a weekly cadence, each one opening a new region stocked with lakes, pumps, and treasures to chase. The latest of these, World 4, is the current headline for a game that regularly holds over 6,000 players at once (about 6,200 in a session right now).
The game has drawn well over a million and a half visits and thousands of favorites since launch, and its regulars treat each Friday expansion as the week’s main event. World 4 is the active region now, and the next one is already on the way.

How often expansions land
A new World Expansion drops on a weekly rhythm, landing every Friday at 1:00 PM ET. There is a single weekly slot rather than several staggered ones, so the clearest way to think about it is one worldwide moment that falls at a different clock time depending on where you play. Here is where that Friday slot lands across the major regions:
- US East — 1:00 PM ET, Friday
- US West — 10:00 AM PT, Friday
- UK — 6:00 PM GMT, Friday
- Central Europe — 7:00 PM CET, Friday
- India — 11:30 PM IST, Friday
- Japan — 3:00 AM JST, Saturday
- Eastern Australia — 5:00 AM AEDT, Saturday
Our best estimate for the next expansion, drawn from that steady Friday schedule, is Friday, November 20 at 1 PM ET; we confirm the exact drop once the developer posts it. The next time and the usual window are also on the card above.
What’s new in World 4
World 4 is the current region to work through, and it is the biggest reason to jump in this week. It opens with:
- 15 new lakes to drain
- 12 new pumps to speed up the work
- 54 new treasures hidden across the region
- 4 new eggs and 21 new pets to collect
Tips for catching the next expansion
- Set a reminder for Friday around 1:00 PM ET; if that clashes with your day, the regional list above shows the most convenient window for you.
- Log in near the start of the slot — the new lakes are busiest and most rewarding to clear in the first hours.
- Miss it? There is no penalty. The region stays in the game, and another expansion comes around the following Friday.
- Bank a few spare pumps beforehand so you can start draining the moment the new world unlocks.
How World 4 fits the game’s rhythm
Expansions are the backbone of how +1 Drain Water for Treasure grows. Earlier regions like the World 2 Expansion built out the map the same way, and a separate Pets Update added to the collectible side between those drops. World 4 continues that weekly pattern of widening the map, so the game’s content ladder keeps climbing one Friday at a time rather than arriving in occasional large patches.
