Posts: 5 Country : United Kingdom | DavidCollison posted @ 2013-03-23 7:49 PM Thanks for an interesting set of puzzles. I will be interested to see the answer for Rank Killer as I think I must have misunderstood the rules. I got stuck three times in the bottom left corner (a delay which later meant that I missed out on typing the answer for Holt/Cold Thermometer by about five seconds ). In case there is a problem with Rank Killer, I'll explain my logic. r9c1 was the 5 of 1/2/3/5. The vertical 1/2/3 meant r5c2 had to be 4 rather than 3 with r7c1 as 8 to be third and r5c1/r6c1 as 6/9. r9c6 had to be 4 because r9c1 was already 5, which also gave 7/8/9 from r9c7 onwards. On r9, that left 1/2/3/6 to place. r9c4 had to be at least 3 to be third but could not be 6 because 6 plus a higher number in r7c4 would be too much for a four-cage total of 14. So, r9c4 is 3. That makes r8c4 and r9c5 1/2. 1+2+3+8=14 making r7c4 8 which clashes with r7c1. Hope that made sense. Thanks again, David. | ||||||||||||||||||

I have planned to write some lines about each puzzle as soon as the test is over, with at least the first important steps in the solving process. I hope that will help. | ||||||||||||||||||

Broke both the Clones and Greather than X 3 times. Knew my submission for the second one would be wrong, but had no time left, so thought. you never know. | ||||||||||||||||||

A beautiful test.Many thnks to the author for this wonderful test.I had great fun solving the test. Got a deja vu of the masyu puzzle in puzzle marathon after seeing the primes without any dots.It is a good way to take the players by surpise.The conventional thinking gets disrupted totally.I was hoping to tackle this puzzle by making pencil marks of 1379 at the end of the dots. Because of the surprise factor this puzzle took me more time to solve than the hot/cold thermometer! Hope to solve the remaining puzzles some time later. One thing i would love to add here is the practise puzzles that the author posted before the test laying the foundation for the test beautifully. Excellent test!!!I really enjoyed it!! | ||||||||||||||||||

Posts: 42 Country : United States | PuzzleScott posted @ 2013-03-24 12:03 PM What do the instructions mean, in Perfects Squares and Primes, when they say "This constraint is not valid for vertically adjacent cells"? Does it mean vertically adjacent cells aren't constrained, so they can even have or not have the pattern? (square or prime) Or does it mean no two vertically adjacent cells can have the pattern? If the latter, kropki-like puzzles usually handle that by the presence or absence of a square or diamond, without a confusingly worded rule. | ||||||||||||||||||

Of course I don't want to confuse solvers, but I thought this was the best way to clarify the rules. Sorry if it's not... What I mean is that it doesn't matter what digit combination appears in the columns, primes, squares, doesn't matter, so your first interpretation Does it mean vertically adjacent cells aren't constrained, so they can even have or not have the pattern? (square or prime) is correct. | ||||||||||||||||||

Posts: 42 Country : United States | PuzzleScott posted @ 2013-03-24 2:33 PM Thanks, that was my guess. Perhaps "constraint does not apply" instead of "constraint is not valid"? Also, working the IB examples clarifies the question. Thanks! | ||||||||||||||||||

Posts: 337 Country : Switzerland | Fred76 posted @ 2013-03-24 7:29 PM Thank you for this wonderful test ! The set was really enjoying, well balanced, and all sudokus were perfectly constructed. On a personal note, I broke the thermo-sudoku 2 times and hadn't enough time the 3rd time (there was 3 minutes left). It's a pity, because without these mistakes, I think it was within my reach to solve all sudokus in 120 minutes. Fred P.S.: and I forgot to say that I look forward to solve more of your sudokus during the next DSM (and I hope without mistake) Edited by Fred76 2013-03-24 7:36 PM | ||||||||||||||||||

Posts: 225 Country : Thailand | tamz29 posted @ 2013-03-24 8:34 PM I went straight for the Greater Than X and systematically tried X=1,2,3,4,5. None worked for me. Can't wait for the answers and the intended solving path. Basically this was a 100 minute test for me because that first puzzle took away 20 minutes with no points. :( Great sudokus from Richard as usual. I liked how there's plenty of practise puzzles that are available before the test. | ||||||||||||||||||
