Pipeflow is a new variant of Pipelink where direction matters.

• Play on Penpa+

__________________________

Draw a single, unidirectional, non-branching, closed loop, that fills every cell in the grid.

• The loop may cross itself, but not on cells with arrows.
• Arrows indicate the direction in which the loop exits a cell.
• Crosses indicate where the loop must cross itself.
• If a loop crosses itself, it will always go straight across.

Pipeflow Example

I would love any feedback I can get. I just recently came up with this variant and am still curious as to what people think.
