Flow Bridges

Think outside the single-plane box. Use bridges to connect all pairs and fill the entire board.

How to Play

1

Connect the Dots

Drag your mouse or finger to link dots of the same color with a pipe. Every pair of dots must be connected.

2

Use the Bridge

Bridges allow two different paths to cross. One pipe goes horizontally through the bridge, while the other goes vertically.

3

Fill Every Cell

A puzzle is only solved when all dots are paired AND every single tile on the grid is occupied by a pipe.

Flow Strategy

Perimeter Priority

Connect the dots along the edges of the board first. This naturally forces the bridge-reliant paths toward the center of the grid.

Identify Bottlenecks

Look for bridges early. Usually, only two specific colors can cross a particular bridge without breaking other paths. Solve these first.

No Empty Spaces

If you connect all dots but have empty squares, your paths are too direct. Try snaking your pipes to take up more space.

Common Questions

Can I cross lines anywhere?
No, you can only cross lines at the designated "Bridge" tiles. On regular grid tiles, pipes cannot intersect.


What happens if I cross a regular line?
Crossing a regular line will "break" the existing flow. You'll need to re-draw that pipe to complete the circuit.
