Brasswater Pipes

Brasswater Pipes takes you into the engine room of an old Victorian pumping house. The board is a wall of cream glazed tiles in a riveted cast-iron frame, and every tile holds a thick copper pipe: a straight run, an elbow, a tee, or a tap with a brass valve wheel. In the middle sits the pump.

Tap a tile and its pipe turns a quarter turn. When two pipes open towards each other they join, and water from the pump runs on through them; every pipe it reaches turns blue inside. Your job is to turn the pieces until the water reaches every single pipe and no open end is left spilling. There is often more than one way to do it, and any way that fills every pipe counts.

The first boards are small, three tiles by three, so you learn how the pieces fit. They grow slowly, all the way up to eight by ten, with a smaller board every few numbers to catch your breath. Some boards wind in long runs, others branch out into many taps.

What you get
- Numbered boards without end, each one made to be solvable
- Today's pipework: the same board for everyone each day, and a streak for the days you finish it
- Undo is always free, and a turn never costs you anything
- A hint turns one pipe into place and locks it, starting from the pump; the first hint on every board is free
- Small water drops show where a pipe that already has water is left open (you can switch them off)
- No timer, no score and no way to lose; leave a board and it waits for you
- Large tiles, clear contrast between full and empty pipes, and TalkBack support with a Turn action for every tile

Brasswater Pipes works offline. Ads pay for it: a banner below the buttons, a short ad now and then when you go on to the next board, and, only when you tap for one, an ad that gives an extra hint.
