# Pipe Flow

> Turn the pipes until every one carries water.

Turn each pipe a quarter turn. Water runs from the spring through every opening that meets. Today's grid is the same for everyone. Practice opens larger grids as you clear them.

## How to play

1. Tap a pipe to turn it a quarter turn. On a keyboard, arrows move and Space turns the pipe you are on.
2. Water leaves the yellow spring and follows openings that meet. The grid is done when every pipe is wet. Undo turns the last pipe back.
3. Three stars means every pipe is wet inside the time for that size. Twice that time is two stars. Slower is one. Pause stops the clock.
4. Today's grid is one for everyone, and finishing it once a day grows your streak. Practice opens larger grids as you clear them.

## Tips

- Turn a straight pipe twice and it points the same way. A corner needs the right quarter.
- Follow the dry pipes out from the spring. A branch that does not meet is the one to turn.
- Undo turns the last pipe back. The clock keeps running until you pause.
- Three stars is the time for that size. A slower clear still fills the grid.

## Questions

### Is it free?

Yes. It is free in the browser, with no download and no sign-up needed. Coins are for fun and can never be bought.

### Is today's grid the same for everyone?

Yes. Today's grid is one 6 by 6, from the date. Practice grids are your own, and they get bigger as you clear them.

### What earns three stars?

Fill every pipe inside the time for that size. Twice that time is two stars. Slower is one. Pause stops the clock.

### Can I play on a phone?

Yes. Tap a pipe to turn it. Undo sits under the grid, so it never covers a pipe.
