Posts: 170 ![]() ![]() ![]() ![]() Country : Germany | rob posted @ 2015-10-28 3:07 PM For Anglers, we asked for a couple of rows in the German qualification, with I=straight, L=turn, F=fish and -=blank (maybe X would be nicer there). That worked out quite well. Not that I'm suggesting you change the code now, just for future consideration. | ||||||||||||||||||

In other words ,do every given circle need to be connected by bridges regardless of whether it is filled with number or not ?I saw a puzzle where even un-numbered islands had to be used to make the system connected.... All islands will be numbered in the test. | ||||||||||||||||||

The example has an unused cell, so I'm sure the answer is 'No'. Rohan is partially right as angler puzzles can be created without using all grid cells like in the IB. You can always quickly check the sum of the anglers to check if all cells will be used or not :) However to avoid unnecessary computation let me announce that all the angler puzzles in the test (including multi-anglers) WILL USE ALL CELLS IN THE GRID. | ||||||||||||||||||

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. | ||||||||||||||||||

Posts: 668 ![]() ![]() ![]() ![]() ![]() Country : India | swaroop2011 posted @ 2015-11-01 7:00 AM Puzzles were nice but I believe they were tough. Lot of new tricks in lots of puzzles. 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 | ||||||||||||||||||

The fourth one is based on transfer of polarities across rows (transfer = number of unbalanced vertical magnets across the two rows). Look at the number of vertical magnets required across rows 4 and 5, 5 and 6. Also look at columns 6 and 7. | ||||||||||||||||||

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 |
