How to play Hexflow
One tap to learn. The glow does the teaching.
1
Every hexagon holds a piece of pipe. Tap it to spin it one step clockwise, shift-tap to spin it back.
2
Pipes join only when two neighbours point at each other. Everything the source reaches lights up the moment you get it right.
3
Win by lighting every tile with no loose ends left over. Par is the fewest turns that would have done it.
4
Arrow keys move, Enter turns, Shift+Enter turns back, L locks a tile. U undoes, H hints, R resets.
