The vexing hex-swamps

The hex-based swamp is a variation of the plank puzzle concept proposed by Graham. The hexagonal grid opens up a few more puzzling conundrums for intrepid swamp explorers to deal with, one obvious one being the choice of direction approaching the exit stump. Do you approach from above or from the left? A maze that offers a choice of exit routes is probably offering a white-hole and only one of those exit routes is reachable. If you are inclined to try and work a maze backwards, a white-hole is an extra hurdle to deal with.

Two sample puzzles are offered here and there are more to explore as part of the new HTML5 collection available at Henleymob. Many of the hex-swamps play on the word Twist thanks to their unique ability to seemingly spin you on one spot. For instructions please see the original planks page.
