The short answer
Open Bloom Circuit and start the first garden. Click or tap a tile to turn it a quarter turn. Connect every channel to the brass tap and close every open end; the board is solved when the whole garden is watered. There is no timer.

Bloom Circuit is a water-routing puzzle, the kind many people know as a pipe puzzle or connect-the-pipes game. Each board is a grid of ceramic tiles with channel pieces: end pieces, straights, bends and junctions. Your job is to rotate them until one connected network runs from the brass tap to every tile, with no channel ending in the open.
It is set in a rooftop garden above a lantern-lit city. When the network is complete, water flows through it and the flowers bloom, a small reward that never gets old.
The campaign has 200 puzzles in ten chapters. Boards grow from 3×3 to 6×6, so the first ones take seconds and the later ones make you think. There is no timer, and a single board fits into a short break.
How a board works
There are only a few rules, and they are the same on every board.
Turn a tile
Click or tap a tile to rotate it a quarter turn clockwise.
Connect to the tap
Every tile has to be part of one network that starts at the brass tap.
Close every open end
No channel may point at nothing. When every end meets another, the board is solved.
Leave the fixed tiles alone
The tap and tiles marked as fixed never turn. Use them as anchors.
Undo freely
Undo and restart are unlimited. On a computer, Z undoes, R restarts, H gives a hint and Escape pauses.
Pipe puzzle tips that really help
Start at the brass tap and in the corners. A corner tile fits in very few ways, which tells you a lot about its neighbours. Fixed tiles work the same way: they cannot move, so the tiles around them must fit them.
An open end pointing at the edge of the board is always wrong. If you see one, that tile needs another turn. This simple check solves a surprising number of boards on its own.
Work outwards in small steps rather than jumping around. Once a tile is clearly right, leave it and move to the next uncertain one. If a section turns into a knot, undo back to the last point you were sure of.
Three rules that solve most boards
Water never runs in a circle. Every tile joins the network exactly once, so a finished board never contains a closed loop. If two tiles would close a ring, one of them is wrong.
A fixed tile is already turned the right way. On later boards, a few tiles are locked in their solved position, so you can build outwards from them with confidence.
A tile with a single opening is an end piece. It must point at a neighbour that opens back toward it, never at the edge or at a tile with a closed side facing it. End pieces near the edge often have only one possible direction.
Boards grow slowly: the first four are 3×3, then come 4×4 boards up to level 20 and 5×5 up to level 40. After that, 4×4, 5×5 and 6×6 boards take turns, so a big board is usually followed by a breather.
Stars, hints and the daily puzzle
Hints are free: each one turns one tile one step toward the solution. They do lower your star rating, though. Three stars need no hints and no more turns than the reference solution, so a hint-free retry is a nice challenge once you know a board.
Every board can be solved. Each one is built from a connected layout with a known solution, and every campaign and daily board is checked before release.
A new 5×5 daily garden appears every day at midnight UTC. Finishing three different puzzles in one UTC day earns 10 bonus seeds, and ten in one week earns 25.
Your rooftop garden, phones and saving
Seeds from first clears and better star records buy decorations for your six rooftop plots. Your first three-star clear pays for the first one. Three garden palettes unlock after 0, 5 and 15 completed campaign levels; they change the look, never the puzzles.
Bloom Circuit plays with mouse or touch in portrait or landscape, with a compact layout for short landscape screens. The game is available in 30 languages.
Your progress, garden and the puzzle in progress save automatically in this browser, including the undo history, so Continue picks up exactly where you stopped. Clearing site data removes the save, and it does not sync between devices.
Questions you might still have
Is Bloom Circuit free?
Yes. It is free to play in the browser, without an account or a download.
Can a board be impossible?
No. Every board has a known solution, and every campaign and daily board is checked. A hint turns one tile toward that solution.
Is there a time limit?
No. Bloom Circuit has no timer at all. Take as long as you like on every board.
Do hints cost anything?
Hints are free and unlimited, but they lower your star rating for that board.
When does the daily puzzle change?
A new 5×5 board appears every day at midnight UTC.
Can I play Bloom Circuit on my phone?
Yes. It works with touch in portrait or landscape, with a compact layout for short landscape screens.
Does undo remove a hint from my score?
No. Undo takes back a turn, but hints you used still count until you restart the board.
