Rectilinear - Pit Khiam Goh by Tom Lensch

I was surprised by this tray puzzle from Tom, at first glance it appears somewhat trivial but once you start to try to solve all of the challenges it becomes quite clear how clever this puzzle is!

Here’s an excerpt from Kevin’s blog:

“This is a series of 5 challenges all marked out by lovely laser etching inside the tray. The aim is to place the start and end pieces as shown in the tray and then place the other pieces so as to create a single continuous pathway to join them together (the walnut squares are blank fillers)

It looks easy, doesn't it?”
