The Hamiltonian Circuit

Started playing this after seeing the developer n Jeopardy. The puzzles is great, and reminiscent of other circuit completion puzzles like Nikoli Slitherlink, and Kaser’s Willa’s Walk. So why four stars? The app itself feels like a minimum-viable product and could use a little more work. In particular, the lack of an undo/redo button is not great. I find myself having to hit reset if I paint myself into a corner and would prefer to tap undo a few times. Also when you start the app up, you have to do some menu diving to get to your last puzzle. This shouldn’t require more than a single tap.

Would be 5 stars, but I can't seem to go back and re-play completed puzzles? I love the minimal interface.

Just downloaded this today and am already addicted!

A good, challenging puzzle game. But there’s no reason for it to run as hot or burn through my battery like it does. So what’s it doing in the background?

It took me very little time to go through a set of problems I was charged for. Doesn’t make sense, and not in line with the cost of other games.

I love this game! Unfortunately I don’t understand how it’s scored. At the end of each level a percentage is given based on the number of grid spaces in the puzzle, however it’s unclear what the scoring criteria are. Still worth every penny since it’s satisfying enough to solve the puzzles. A very challenging game and nicely designed!

See the title.

The game is a great idea (how could you go wrong with an NP-complete problem), and the puzzles are designed well too :). However, it seems in the newest update, many of the levels that I'd already finished are now marked incomplete. So, the packs I was in the middle of are now especially difficult to navigate. Moreover, while the pencil mode is super helpful, in hex puzzles it does not connect with the normal drawing mode, leaving a pretty significant discontinuity. Thanks for the help!

In my opinion, the price is steep for such a minimal game. Additionally, you cannot play the “giant” levels on iphone devices, you HAVE to have an ipad? Why can’t the dev just let us zoom in?

Love the game, I’m playing thru a second time. But I feel like some of the Nearly Impossible levels can’t be solved without guessing. Is that true? I feel like I’ve learned all of the tricks to solve.
