Drain Water for Treasure World 4 Update

World 4 is the current headline expansion for +1 Drain Water for Treasure, the Roblox incremental simulator by ClixStudios. This dedicated patch page covers what shipped, when the live window runs, how to play the update efficiently, and how to bank progress before World 5. Pair it with the broader Updates Hub and the strategy deep dive in World Expansions.

As of 2026-11-15, the experience sits around 2.2M+ visits, roughly 7–8k concurrent players at busy peaks, about 10k favorites, and a 12-player server size. Do not confuse this title with “+1 Drain Water Per Click”—codes, Worlds, and systems below apply only to Drain Water for Treasure.

Schedule window

Milestone	Timing (2026, ET)
World 2	Friday, Oct 30 ~1:00 PM
World 3	Friday, Nov 6 ~1:00 PM
World 4 live	Friday, Nov 13 ~1:00 PM
World 4 window ends	Thursday/Friday turn ~Nov 20 ~12:55 PM
World 5 expected	Friday, Nov 20 ~1:00 PM

Treat World 4 as a week-long frontier band: it went live Friday Nov 13 ~1:00 PM ET and is expected to run through roughly Nov 20 ~12:55 PM ET, with World 5 lining up immediately after at ~1:00 PM ET. Friday drops near 1:00 PM ET remain the planning anchor—show up early if you want first access to new lakes and Pump tiers.

What World 4 added

Highlighted content counts for the World 4 window:

• 15 lakes — more drain stands and longer money routes
• 12 pumps — a taller upgrade track and sharper Money sinks
• 54 treasures — denser sell tables and Index completion goals
• 4 eggs — the frontier hatch pool for this band
• 21 pets — equip, merge, and rank targets that define mid-week power

That package does not invent a new fantasy. You still tap Water, drain Lakes, collect Treasures, sell for Money, upgrade Pumps / Backpack / Speed / Luck, hatch with Lucky Rolls, fill the Treasure Index, and Rebirth when recovery is sane. World 4 simply raises every ceiling at once. Mechanic primers live in How to Drain Lakes, Pets and Eggs, Treasure Index, and Upgrades and Rebirth.

How to play the World 4 update

1. Log in near drop time (or as soon as you can after Nov 13) and redeem every live string on the Codes Hub before you grind.
2. Scout new lakes once manually so you learn stand locations, sell paths, and crowded hotspots in 12-player rooms. Skip jumping straight into long AFK on obsolete water.
3. Spend Money toward new Pump tiers first, then Luck, then Backpack, then Speed—same order as the Tier List Hub. Speed helps on a fifteen-lake map, but it still should not eat your first Money spike.
4. Hatch World 4 eggs with Lucky Rolls, equip the best pet immediately, and merge duplicates instead of hoarding dead inventory.
5. Run two mental routes: a money loop on the strongest drains you can finish, and a separate Index pass for missing Treasure entries (Treasure Index).
6. Claim daily and boss-style rewards when they appear so you do not leave free Rolls or Money on the table (Daily and Boss Rewards).
7. Delay Rebirth until you have seen new Pump prices and can reclaim power across the twelve-pump track the same session—or the same evening.

New or returning accounts should still open Getting Started for the base loop, then push into World 4 lakes as soon as Pumps allow. Playstyle variants (active optimizer vs longer semi-AFK) are covered on the Players Hub.

Automation and patch-day caution

If you use third-party tools from the Scripts Hub, disable Auto Buy / Auto Hatch for the first pass after a Friday ship. Menu labels, lake lists, and egg filters can shift when twelve pumps and four eggs land together. Prefer testing on an alt; ban risk is real, and nothing on that hub is an official ClixStudios product.

Related progression footage

The embedded video below is World 3 Crystal Cave footage. It is not a World 4 trailer, but it shows the same progression language—drain pacing, HUD flow, and how a new band feels after a Friday expansion—so it remains useful context while you clear World 4’s fifteen lakes.

Prep checklist for World 5 (Nov 20 ~1:00 PM ET)

World 5 is expected Friday, Nov 20 ~1:00 PM ET, right as the World 4 window closes. Use the last days of World 4 to arrive ready:

• Bank enough Money to grab at least one new Pump tier on arrival.
• Keep some Lucky Rolls unspent if a new egg tier is likely within hours; otherwise hatch the current best eggs rather than hoarding forever.
• Clear Backpack clutter and equip your strongest World 4 pet before the drop hour.
• Finish easy Treasure Index gaps so you are not Index-starved while learning World 5 lakes.
• Avoid a blind Rebirth minutes before 1:00 PM ET unless recovery is already proven.
• Favorite the experience and follow ClixStudios destinations from the Official Links Hub so the join button is one click away.
• Re-skim this page, the Updates Hub, and World Expansions after World 5 ships in case counts or cadence shift.

World 4 rewards accounts that treat the week as a focused expansion, not a casual AFK on tutorial water. Clear the fifteen lakes you can actually drain, climb the twelve-pump shop, hatch the four-egg frontier pool into the twenty-one-pet roster, finish Index gaps across fifty-four treasures, and walk into Nov 20 ~1:00 PM ET with Money, Rolls, and pets ready for World 5.
