Description
Looking for a challenge that will build your abstract thinking skills? Try The Hamiltonian Circuit, a fun, relaxing puzzle game that's easy to learn and tough to master.
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!

Brilliant game
There’s very few bells and whistles, but this is pure puzzling at its best. Simple to learn, but increasingly challenging. You get a decent amount of free puzzles, and the paid ones are reasonably priced. Although all the puzzles take the same form, progression is excellent. So far I’ve completed just over 570 of them, with each one taking between 1 and 5 minutes. It’s a great way to while away the time. There are plenty of far flashier games in the App Store, but very few that are as satisfying as this.

Thanks for the great review! We're working every day to make it better and better, and to make more puzzles. If you can do the really big puzzles in 5 minutes, you're faster than I am!
Great game to keep you sharp
I forgot about this game for a bit, after I got a new phone - but I do hope it is doing well l - as I am not getting back to it and getting addicted again! :)
Developer Response ,
We're keeping it updated, with performance improvements, bug fixes, and even more puzzles. Thanks for your support!
Fun game, 95% of it is behind a paywall
Figured out how it works only to be confronted with a paywall to access the rest of the game and I can’t seem to replay any of the old levels
Developer Response ,
Thanks for the feedback. We have made all puzzle packs free - no more paywall at all. We provide thousands of puzzles, but if you still want to replay old puzzles, let us know - it's not a problem to make that work.
