## The Hamiltonian Circuit Description
Find a path that visits every square in the grid, avoiding walls and never crossing itself, to create one continuous circuit. 

To get the hang of things, start with one of the simple 4x4 grids. Plot your moves carefully. Try to think ahead; not just by one square, but by four or five. If you think you've made a mistake, trace back over your line. It will disappear.

If you really get stuck, press Hints. Any mistakes will turn red, then disappear. But if you're on the right path, we'll add a line.

There's only one solution for every puzzle. When you find it, you'll know.

Puzzles start with 4x4 grids and go all the way to 20x20. The bigger puzzles are very challenging and can take hours to solve. If you have to quit in the middle of one, don't worry: your progress is automatically saved. 

Many find working on these circuits meditative; others reach for the ibuprofen. But no matter which camp you find yourself in, know you're exercising your abstract thinking skills and challenging your brain in ways that actually matter.

Inspired by a puzzle created by Irish mathematician William Rowan Hamilton in 1856, these circuits start off easy and get hard. Really hard. Good luck!

## The Hamiltonian Circuit Reviews in United States

### ****- "Good puzzles!"
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.

### ****- "Fun Game"
Would be 5 stars, but I can't seem to go back and re-play completed puzzles? I love the minimal interface.
-- soaresaurus, 2024-09-27

### ***** "Addicting game"
Just downloaded this today and am already addicted!
-- humanoftheyear, 2024-06-05

### **--- "Good game, but…"
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?
-- barcodez, 2023-12-05

### ***-- "Nice game, price too high"
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.
-- BobTheUser, 2022-01-17

### ***** "Great game but the scoring is confusing"
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!
-- NolanWritesAReview, 2021-12-26

### ***-- "Okay puzzle, few free levels"
See the title.
-- 8886637228, 2021-12-23

### ***-- "Amazing Game (with bugs)"
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!
-- Avid "Sweller", 2021-12-22

### ***-- "$18 for the full game?"
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?
-- The Feet of a Statue, 2021-11-28

### ****- "Nearly Impossible levels require guessing?"
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.
-- curt_l, 2021-11-11
