Thought I'd share with everyone a new puzzle type I came up with.

The rules are very simple, but the puzzles can be quite tricky, (even at this modest size - if I went bigger they could be very tough indeed).
The first is reasonably easy.
The second is trickier, and has two very slightly different solutions (but depending on what answer key was asked for, could very well give identical answers).
I'd be very appreciative if people could take a look and give me some feedback.

I think it needs an indication that a circle can be used more than once and that you don't need to use every circle. As a general thought, I'd be interested to know what sort of answer key you'd use, as with the repeated use of some circles, it's a bit fiddly to retrace your route correctly.

It's a nice idea - reminds me of something where every square was used and the circles were replaced with A, B, C. Can't remember if it was a path or a loop and, more importantly, where it was (old Akil Oyunlari, maybe, or an old 24H) but that didn't reuse squares, so this looks original.

Nicely done.

This is a great puzzle! I'd be interested to see some of those harder examples
Might be worth saying (because you have an odd grid shape) that you're not allowed to escape outside the circles.

You reminded me of this site, and "multi-state mazes" in general:

Honestly? I'm struggling with the first one, let alone the second! :D

Thanks guys.

I'll tighten up the rules with regard to revisiting / not visiting cells, and only moving to adjacent cells.

Ronald, I've been trying to make a bigger one, but making a long route where there isn't a shortcut is proving difficult.

These aren't quite like what we're used to - cells can be reused, not all cells need to be visited, lines can cross...
Nice puzzles Elliott. Not too hard once you work out the rules... (and work from both ends at the same time) Larger grids would definitely be challenging.
