How to Play
Currents
Currents is a Flow Free-style pipe puzzle. Draw a pipe between every pair of matching colored dots so that no two pipes ever cross or share a square, and every square on the board ends up covered.
Rules

- Draw a continuous path connecting each pair of matching dots.
- Pipes can't cross each other, and no square can be shared by two different pipes.
- Every square on the board must be covered by exactly one pipe. No empty squares may remain once the puzzle is solved.
- Drag from one dot toward its matching partner to draw a pipe; drag again to redraw it.
Tips & Strategy
- Start with the pair of dots that has the fewest possible paths between them. Dots in a corner or along an edge are usually the most restricted.
- Remember that every square must end up covered. A short, direct connection between two dots is often wrong if it leaves squares elsewhere impossible to reach.
- If a square only has one empty neighbor left, the pipe running through it is forced in that direction.
- Work from the edges of the board inward. Corner and edge squares have fewer possible pipe directions passing through them.
Frequently Asked Questions
- Do the pipes need to cover the whole board, or just connect the dots?
- Both. Every pair of matching dots must be connected, and every square on the board must end up covered by exactly one pipe.
- Can two pipes cross each other?
- No. Pipes can never cross, and no square can belong to more than one pipe.
- Is Currents the same as Flow Free?
- Currents follows the same core rules as the classic puzzle Flow Free, with the added requirement that every square on the board must be covered, plus its own layout generated and checked fresh each day.
