What is +1 Drain Water Per Click?

+1 Drain Water Per Click is an incremental simulator that Wrestling Elephant Studio published on Roblox on July 25, 2026. Every click trains your Water level; you spend that Water draining a pool, and the fish waiting at the bottom are sold for Cash or displayed in an aquarium that pays out every minute. Five weeks in it has passed 23.9 million visits with 22,432 people playing at once and a 99% like ratio — the figures and the API each came from are on the live numbers page.

Almost every search for this game is a search for codes, so that is where this site starts: eight codes are currently reported working, four of them printed in the official Roblox description itself, and the public trackers openly disagree about what three of them give you. The codes page prints that disagreement as a table instead of picking a winner. Past that, the useful decisions are which boost to buy first (boost priority tiers), how the four fish mutations and their weather events multiply a catch, and when to spend a Rebirth. The update calendar tracks the official event windows — the next one opens September 4, 2026.

Get Started in 5 Steps

  1. Claim the codes first. All eight hand out pets, and pets multiply the Water you gain per click — so redeeming before your first drain changes the whole first hour. Copy them here.
  2. Learn the loop, not the menus. Click to train Water, walk to a pool, drain it completely, then collect the fish that appear at the bottom. The beginner guide has the controls and the first-run order.
  3. Decide sell or display. Cash now, or a good catch parked in the aquarium for income every minute. Early on, sell; once you own display-stand space, keep the rare ones.
  4. Fix your slowest step, in order. Pumps before pets, pets before auras, and backpack space the moment a full bag is what sends you home — see the boost priority tiers and the upgrade guide.
  5. Watch the label above each fish. Gold, Diamond, Venom and Hole multiply what a catch is worth by up to 20x, and Poison and Black Hole weather raise the odds of the rare two: mutations explained.

FAQ

Is it called +1 Drain Water Per Click or 1 Drain Water Per Click?

The Roblox experience is titled +1 Drain Water Per Click, and while an event is running the title also carries a tag, for example [Cthulhu]+1 Drain Water Per Click. Most people type it without the plus sign, so 1 Drain Water Per Click, drain water per click and plus 1 drain water per click all point at the same game. Do not confuse it with the other +1 titles from different studios, such as +1 Superhero Evolution or +1 Web Swing Escape.

What are the working +1 Drain Water Per Click codes?

Eight codes are currently reported active and none are listed as expired anywhere: Fixed1, Fixed2, CCoins, CDraw, Cthulhu, AdminAquarium, MythicFish and WaterHappy. Four of them — Fixed1, Fixed2, CCoins and CDraw — are printed in the official Roblox experience description itself. The codes page lists which sources back each one and where their reward labels disagree.

Does +1 Drain Water Per Click have an official Trello or wiki?

No creator-owned Trello board or wiki has been published. The verified official channels are the Roblox experience page and the Wrestling Elephant Studio Roblox group, which had 644,408 members when this page was last checked. Everything else, including this site, is player-kept.
