Posts: 349 ![]() ![]() ![]() ![]() ![]() Country : India | amitsowani posted @ 2015-11-03 4:11 PM Congratulations to Ulrich, Michael and Bram for topping the international chart, and to Rohan, Rajesh and Swaroop for topping the Indian chart. Here is the result of voting for puzzle types : Anglers > Magnets > Dominos > Hashi > Arrows The most consistent feedback is that the test contained a large percentage of hard puzzles. We had realized this before the test and in an attempt to balance the difficulty of the puzzles replaced one arrow and magnets puzzle with easier ones. The difficult ones might get used elsewhere (2017?) One option which would have helped is to reduce the grid sizes, especially for magnets. Another concern was with regarding the distribution of points which becomes difficult when the puzzles have narrow solving paths. Also the fact that all the dominos were created by Deb and the rest of the puzzles by me added to the complexity. A little more extensive testing including solvers having varying levels of solving speed might have helped. Thanks to Deb and Prasanna for helping with the organization of this test. Special thanks to Zrinka and Bram for test solving the puzzles at a short notice. Thank you everyone for participating. I will be posting a set of hints to help the beginners on some of the harder puzzles separately. | ||||||||||||||||||

This one was my personal favorite for the entire set Magnets 1 : Easy puzzle used to replace a harder magnets puzzle Magnets 2 : Existence of half the grid size (8/2 =4) in one of the polarities forces a few bars to be magnets Magnets 3 : Min max - A less loaded column surrounded by two heavily loaded columns. Magnets 4 : Transfer of polarities across rows Arrows 3: 3 in the center gives good starting point Arrows 4: Interaction of two large numbers in the corners (4 and 5) along with the smaller numbers int he remaining two corners (2 and 3) Anglers 2: Parity - Only one angler can reach the fish on bottom left as it has different parity compared to all other fish Anglers 4: Reach ability of top left fish to an angler Multi-anglers- Count of total number of anglers and how many anglers can reach each fish. | ||||||||||||||||||
