- All sections must be connected into a single, contiguous network.
- The whole network is contained in the grid, and no pipes may run outside the grid.
- Bulb-shaped pipes with a single connection are terminations (dead-ends).
I'll agree with other commenters that actually just showing a complete solution is better. Or both!
I think simply having an image of what a solved network looks like would help a lot.
Agreed, I didn’t bother reading the rules and just started clicking. I doubt I would read the rules even if they were written perfectly.
a pic of a before and after puzzle would answer these questions intuitively as well.
