This is something I got for Christmas and have been having fun with. It feels a little Zachtronics-esque in that you're putting basic building blocks together to achieve a defined goal, but it's placing objects on a physical board. Setting it off and watching the marbles clack around for a minute or two is really satisfying (once you iron out the bugs). And sometimes it's just fun to play with something that doesn't have a screen. (The 'undo' function takes a lot longer to run though...)
The puzzles start off pretty easy if you have other experience with binary/logic-themed puzzles - I'd say the first 30 (of 60) felt a bit tutorial-ish in terms of introducing concepts and then providing fairly limited ways to demonstrate that you know why the previous setup worked. But after that the guiderails come off a bit, and there have been a few puzzles where I've had to try a few different approaches or go away for a while and think things over.
It's more expensive than an electronic game because of the physical parts (USD70 + shipping), but I'm glad I have it. (Mine came from a local board games shop which saved a fair bit over the online store price.) You can put together an electronic version using the simulator at
