This app guide for Pou!
The goal is to connect two Pous of the same color by drawing pipes from one Pou to the other, until all Pous are connected and every space is filled. You can't leave a single space empty even if you've connected all Pous together.
There's a game timer, shown as a large green bar that slowly ticks away. Completing a round will add extra time to the timer.
The final score is the number of rounds completed when time runs out.
