If you are stuck on some of the levels in the game Flow Free, you can find walkthroughs/solutions for all levels of the 9×9 matrix here. The game is about connecting the matching colors with a pipe to create a flow. Just pair all colors, and cover the entire board to solve each puzzle.
The game is made by Big Duck Games and is currently #1 on iPad!
Flow free features 10 different board sizes with each having 30 free levels. So stay tuned for other board sizes!
