I first encountered Numberlink puzzles in the (numberless) Flow Free app and appreciated them because they were a little more topological than the typical logic puzzle.

At the Joint Math Meetings, some folks from the VCU Breakthroughs team presented some activities on knots using a silicone necklace manipulative. Today we'll look at a set of puzzles inspired by that.

Here we'll look at some topological puzzles originally cast in terms of hanging a picture frame.
