Puzzles were really nice. Enjoyed solving most of them. I felt the set is quite hard for PR. And the way our scoring system is set up, I won't be surprised if most players' worst performance discarded is this round. I felt the Hashi puzzles were under-valued and the Dominos were over-valued, but might be a personal opinion. Maybe we need to rethink on the scoring system, which is based on the assumption that all tests are 'similar' in difficulty, whereas this one is way off. Really liked the solving paths of Hashi. | ||||||||||||||||||

Found this set really hard.I practised Hashi well before the test but found them too difficult and didn't gain much of an advantage on them.I completed all Hashis at close to 35 mins.Arrows too managed to stall me for quite some time.I found some comfort in dominoes where I managed to gain some quick points and which I never practised before the test....A very hard set .Would have preferred more easier puzzles..... | ||||||||||||||||||

This round felt far more difficult than previous ones. I did enjoy the puzzles that I solved though, and I thought the multi-anglers was very fun. Can someone explain the theme to me though? What does "evergreen" mean? | ||||||||||||||||||

They are just Classic puzzles that have been appearing in contests for a long time. We couldn't have too many standard puzzles in one test, so we split it across two (Classics and Evergreens). Also, a tribute to two really nice tests during the birth of LMI: Evergreens and Evergreens2 :-) | ||||||||||||||||||

Puzzles seemed unexpectedly hard this round. I used to subscribe to CrocoPuzzle and always did the magnet puzzles. I was quite stumped by the harder ones in this set. Even the Hashi puzzles seemed hard and I have quite a bit of experience with these. I barely had time to look at the easy domino puzzles and completely skipped an entire category (anglers). There is usually time to at least scan them. | ||||||||||||||||||

I continued Solving even after the time was over and took around 25 min more to solve few more puzzles. Only left ones were Magents 9 pointer and Arrows 3rd one. Thanks to deb for pointing out the start for Arrows 3rd one. Really lots and lots of new tricks to explore in this round. Performance wise I believe my bad run is continuing after my below par performance in Numbers Round. Hopefully will improve in upcoming rounds. Thanks Amit for Fantastic Puzzles. Would appreciate if anyone can tell the path for Magnets last one. (I could place only 3 magnets in the entire grid after lot of struggle) ? | ||||||||||||||||||

A column with few signs filled (2,2) is surrounded by two heavily filled columns (4,4) and (4,3). This should give you a start | ||||||||||||||||||

Posts: 102 ![]() Country : United States | ghirsch posted @ 2015-11-01 11:25 AM Regarding the booklet formatting, I somewhat prefer the bank in domino puzzles to be formatted as below (or flipped) rather than the way they were in this test. The disadvantage is that it takes up more space, but for me it makes it much easier to think about which dominoes I have already found and which I have left. I don't know what other people's opinions about this are though, so maybe this is just me. ![]() Edited by ghirsch 2015-11-01 11:29 AM | ||||||||||||||||||

Thanks Amit for a challenging set of puzzles. Definitely harder than normal. (And this set was difficult to solve without paper.) Most puzzles would need some tricks and techniques - a good test from a learning perspective. | ||||||||||||||||||

Got through most fairly quickly, but got completely stumped by the hard Hashi's and Magnets and ended up scoring no points in the last 15 minutes. Given the relative short test, and relative to the difficulty levels of the others, I thought those were a bit too hard. My favorite puzzle was Multiple Anglers: very nice! | ||||||||||||||||||

Great test, thank you! It turns out I have some things to learn about Arrows, and also some things to practice -- I missed so many of the "obvious" deductions at first. Edit: I think I should retract my judgement on the point distribution. I just went through my results, and things seem pretty even: * hashi: 1.6 points/minute * magnets: 1.4 * arrows: 0.6 * anglers: 1.6 * dominos: 1.8 The low arrows score is due to a bad performance, not due to difficulty. I did think I got through the magnets very cleanly and found the somewhat tricky deductions immediately, so that one might be a little undervalued. The dominos felt quite easy, but were low-valued accordingly. Edited by rob 2015-11-01 11:03 PM | ||||||||||||||||||

I never figured out how to do Arrows #3 and by the time I decided to move on it was too late to catch up. | ||||||||||||||||||

Arrows #3: I spent over 15 minutes on it and never found the solution or even a reasonable solve path. Hashi #2 and #3 (4 and 5 points) took much longer than any of the Magnets puzzles (8 and 9 points). I am not sure if the point values are aimed at beginners or at seasoned players; if the latter, then they are problematic (Magnets is easier than you seem to think it is), if the former then the overall difficulty of the round is problematic. That said, it was still fun. Apart from Arrows #3. | ||||||||||||||||||

If you're still looking for how to start it, I think the break-in is meant to be the 3 in the middle. There are only four possible arrows that can point to it (no diagonals), and you can quickly find that two horizontal arrows doesn't work, so you need to do two vertical arrows. From there I don't remember running into many difficulties. |
