On: Can water solve a maze? [video]

[pwagland]

Except that this maze clearly has at least two solutions. Straight through the corridor, or via the loop. And that's assuming you don't wander around the loops n times.

[kolinko → pwagland]

Three solutions if you want to be nitpicky. You can go around the clockwise, and counter-clockwise :)

[redblacktree → kolinko]

Infinite solutions. You can take as many loops as you like before continuing to the exit.

[pxeger1 → pwagland]

But, to me, that requires doubling back on yourself (going through the little passageway twice). This is what I meant by my definition of going back on yourself being wrong

[Terretta → pwagland]

Not if your path trace kills you like the lightcycle trails in Tron.
