+1 Drain Water Per Click is a Roblox incremental clicker/simulator. Every click grants Water that is used to drain pools and lakes. Emptying a body of water reveals fish at the bottom, which can be collected and sold for Cash. Cash is spent on pumps, upgrades, and pets that multiply the amount of Water gained per click. Players progress by unlocking larger lakes, rarer fish, stronger pets, and permanent multipliers through rebirths. Mutations on fish (Gold, Diamond, Venom, Hole) further boost sale value and earnings.
A tier list in this game ranks the most important pets, pumps, and progression tools by overall power, water multiplier strength, utility for draining speed, and effectiveness from early game through end-game lakes.
