Flowee
Pipe the right amount of power from sources to sinks on a 3x4 grid, with three new puzzles every day.
Every day: A new easy, medium and hard puzzle every day: route power from source nodes through sum nodes into sinks on a 3x4 grid so every target value is met. New puzzle: Once a day (the game does not state the time).
Flowee is a small daily logic puzzle about adding numbers along pipes. You place numbered sources, sum nodes and sinks on a 3x4 grid and switch on the pipes between them until every sink shows its target value. There are new easy, medium and hard puzzles each day.
About Flowee
Flowee began as a mini-game designed by Rob Clewley for OPERANDi, a science fiction hacking game he is working on; the standalone version was built in Unreal Engine by Pumashock, who also wrote its music. It is free to play in the browser on itch.io, with a name-your-own-price download for Windows and macOS that works offline and includes the soundtrack.
Each puzzle gives you a set of sources, each labelled with a power value, and a row of target values. You place sources, sum nodes and sinks on a small 3x4 grid, then click the pipes between neighbouring nodes to turn them on. A source can feed several outputs, and each one receives its full value. A sum node merges whatever flows into it and points its output at a sink. A sink shows the total of everything that reaches it, and the puzzle is solved when the sinks match all the targets.
The challenge is partly arithmetic and partly layout: there are only twelve cells, so finding a combination that adds up is not enough if the pieces cannot be placed next to each other. Some puzzles have more than one solution. Illegal set-ups, such as a sum node pointing at something other than a sink, are marked in red until you fix them.
Three puzzles arrive each day, easy, medium and hard, so it suits both a quick warm-up and a longer think.
How to play Flowee
- Open Flowee on itch.io and choose Easy, Med or Hard for today's puzzle.
- Read the target values on the right of the board.
- Select a source, sum node or sink from the side and click an empty cell to place it; click a sum node again to turn its output.
- Click the pipes between neighbouring nodes to switch power flows on or off.
- Adjust until every sink's total matches a target and nothing is marked in red.

Tips
- Work out the arithmetic first: which sources, alone or added together, make each target.
- Remember that one source can feed several sinks at its full value, so a single node can serve two targets.
- Put sum nodes in the middle of the grid, where they have the most neighbours.
Questions
How many Flowee puzzles are there each day?
Three: an easy, a medium and a hard one.
Is Flowee free?
Yes. It plays free in the browser; the download for Windows and macOS is name your own price, so it can also be free.
Can a puzzle have more than one answer?
Yes. Any layout that makes every sink match its target and has no illegal connections counts.
Where does Flowee come from?
It was designed by Rob Clewley as a mini-game for his upcoming hacking game OPERANDi, and built as a standalone game with music by Pumashock.
