Fill Water Tank: The Addictive Water Flow Puzzle Game | Play Free!

There's a unique satisfaction in watching a plan come together, especially when it involves the pure, undeniable force of gravity. Welcome to Fill Water Tank, a game that distills the brain-teasing joy of physics puzzles into its most elegant form. Your mission is simple: draw a path to guide the water from the pipe to the tank. But as you'll soon discover, simple doesn't mean easy. You'll need to account for angles, momentum, and devious obstacles to succeed. The gameplay loop is brilliantly addictive: play and earn coin for every perfectly filled tank, which you can use to unlock new level packs and cool visual themes for your water and pipes.

The Color Catalyst Update: A Whole New Flow!

The challenge just got a lot more colorful! We've just released the Color Catalyst update, introducing 40 new levels with a mind-bending new mechanic. In these advanced labs, the water and the tanks have different colors. You must guide your stream through special "Catalyst Gates" to change its color to match the target tank. Sometimes you'll need to split a single stream to fill multiple tanks of different colors, demanding a whole new level of precision and planning. It's the kind of design evolution we love to break down on our official blog.

How to Play: Become a Flow Master

The controls are intuitive, allowing you to focus on the solution, not the interface. Your goal is to fill the tank to the designated line without spilling water.

• Draw a Path: Click and hold your mouse button, then drag across the screen to draw a line. This line acts as a solid slide or channel for the water.
• Release the Water: Once you let go of the mouse, the water will begin to flow.
• Plan Your Line: You only get one continuous line per attempt, so make it count!

What kind of game is Fill Water Tank?

Fill Water Tank is a physics-based drawing puzzle game. It challenges your understanding of fluid dynamics and spatial reasoning. Success isn't about quick reflexes, but about careful planning and creative problem-solving. You must design the most efficient path to guide a liquid from point A to point B, overcoming various obstacles along the way.

What's the best way to earn three stars on a level?

Three-star mastery is all about efficiency. You're rated on two main factors: using the shortest line possible and spilling the least amount of water. Before you draw, visualize the water's trajectory. A perfectly placed curve is often better than a long, straight line. The goal is a clean, splash-free fill using a minimal amount of ink. Many of the best HTML5 games reward this kind of elegant problem-solving.

Is this game considered a type of Hero Rescue?

That's a great way to think about it! While there's no character in a dungeon, the water itself is the 'hero' you need to save. It's trapped behind a valve, and the empty tank is its goal. The level's obstacles are the 'monsters' and 'traps,' and your cleverly drawn line is the heroic intervention that guides it safely home. It's a pure, logic-based Hero Rescue mission.

Do the puzzles get more complex?

Oh, absolutely. The initial levels teach you the basics of flow and angles. Soon, you'll face levels with spinning wheels that disrupt your stream, hot surfaces that evaporate your water, sponges that absorb it, and multiple tanks that need to be filled in a specific order. The game is fantastic at introducing new mechanics to keep the challenge fresh and engaging.
