In your proposed solution, the loop travels straight through both R3C1 and R3C2, which is against the rules.

Does the Ripple Loop example have two solutions (see attached)? Or am I misunderstanding the rules?


Just reiterating what Feadoor already mentioned.

For every pair of adjacent circles, if the loop passes through one of them as straight, it must turn in another.
In your solution, R3C1 and R3C2 are adjacent circles and the loop is going straight in both of them, which is against the rules.

Oh, I see. My misunderstanding was the phrase "edge-adjacent", which I took to mean that two circles were adjacent on an edge of the path (e.g. in the example R1C1 and R3C1 share an edge of the path, and no other circles are between them).

Maybe change the wording in the instructions to simply "For any two adjacent circles, the loop must..."?

Too hard to choose favourite puzzles. All of them were fantastic and a great PR set.

This will go down as one of the best across years.

Thanks a lot Swaroop!

When you have people finishing the test in 27 minutes, it's probably too easy! Despite this, I thought the puzzles were very nice and fun to solve, so overall an excellent test.

Thanks for an easy-raised-to-the-power-of-2 test. The puzzle quality was very decent. I thought the 7-pointer Trio cut and 12-pointeer Nurikabe were overrated though. On the other hand, I struggled 25 minutes to break the tricky loop closure in the centre-left center in the 10-pointer RL!

Lovely puzzle set, although I found it quite hard. That, however, is probably because I am weak at some of these shading variants, but I enjoyed it!

Thanks, Swaroop!
And thanks for dedicating some of the puzzles to Shaheer :) wonderful gesture...

Very hard for me as usual but i am just an average solver. Most were fun enough without the timer, except the ripple loop puzzles. I found even the 2 pointer to be impossible. I solved it several times and even downloaded the instructions/examples again during the test and do not understand where i am wrong. My solution is 320212

Thank you. The aim is to encourage more newcomers and so the difficulty was set towards easier with some challenging stuff for top solvers. I am glad you had fun.

Thank you for the feedback. Sometimes the points can be varying based on the experience, as some of them find shading and loop puzzles easy while some find it hard, so there might be some minor variation in the Points to Difficulty experience. But I hope overall it was as close to its possible. Ripple Loop indeed was challenging.

This is the first set that I was able to complete in time while live.

So I'm excited about that, even if the test seems to have been on the easier side.

I definitely needed to reread the instructions a couple of times in order to find the solutions, especially for Ripple Loop. But overall I'm pleased with my result. Hooray!

Let a = corner with loop arms going down and to the right, b = down and to the left, c = up and to the left, d = up and to the right, - = horizontal, l = vertical, . = empty.
My solution row by row is ..a--b, a-cabl, l..lll, la-cll, ll.acl, dc.d-c
This this leads to the code 320212 which is incorrect. I presume I misinterpreted the rules somewhere but I've never had so much difficulty with a 2-point puzzle.

Thanks for your time and for especially for providing something interesting to do during these crazy times. Please be careful. -bob
