Flow Free: Bridges is an easy-to-learn puzzler with satisfying touch-screen controls, but be ready for a challenge once you hit later levels.
Many people will remember Web-based pipe games where you connect pipes to complete a circuit so water can flow from a starting point to a goal. Flow Free: Bridges is a similar concept, but instead you're trying to connect multiple color-coded start and end points together without crossing the lines. Fortunately, there is an exception to the rule about crossing the lines, with bridge tiles you can make one pipe pass over another to get to the goal. On first playing the game you'll immediately understand the concept, but as you progress the playing boards grow larger and levels get more challenging, requiring plenty of strategy and sometimes several restarts to complete a difficult level.
