17:04 I really underestimated the difficulty of this one, (“How hard can it be with only three possibilities for every cell?”). Not too far into the solution, I spent a long time overlooking a fairly simple deduction, (so wandering all over the gird looking for something without making any progress).

So that’s a nice puzzle that makes me think, “That step was so easy. Why didn’t I find that earlier?!”.
