💧 Waternet

Waternet is a pipe town that will not drink until every joint agrees. Water starts at a single source. Your job is not to invent a river. It is to turn, slide, and argue with the existing pipes until that source can reach every length of the network.

There are three ways to have that argument. In Rotate you stand on one tile and twist it, the way Simon Tatham's Net taught a generation to finish a Sunday. In Slide you never twist a piece at all. You shove a whole row or column in the direction of its arrows, like Netslide, and watch elbows that were almost connected miss each other by one square. RoSlid lets you do both, which sounds generous until you realize the extra verb is also an extra way to ruin a nearly finished grid.

Each mode has five difficulties, from very easy to very hard, and twenty-five rooms in each. That is 375 written puzzles before the random generator starts building rooms that have no published solution sitting in a walkthrough. The rule never changes. Every pipe that can carry water must carry water. A pretty loop that leaves one stub dry is still a failure.

The look can stay in Playdate black and white, or you can press F3 and wake the color skins — twenty-four of them, including tiles that remember old handheld homebrew. Progress remembers itself. You can leave a hard slide mid-row and come back to the same leak.

The pleasure is the moment the last corner flips and the whole map suddenly looks obvious, as if it had been wet the entire time. Until that click, it is just a dry town and one pipe still facing the wall.
