Gravity Puzzle Game - Water Flow

Rating: 7.9/10 - 10 votes

Water Flow is a fun and simple game, perfect for when you need to kill time or just relax. You need to drain containers of weird and different colours of water all the way through long pipes and into the buckets marked with the same colour. Water Flow provides a nice mix between puzzle and physics or gravity gameplay.

How to Play: Once the game has started, pull out the stopper pins by clicking/tapping and dragging them out to remove the blockage and allow the water to flow. You will also earn coins as you win levels, which you can use to purchase a random new colour of water to add some more visual variety as you play. As you progress, the pipe designs will gradually become more complex, incorporating more pins and colours.

Water Flow is supported on both mobile and desktop browsers.
