Posts: 40 Location: China | Thank you for every participant and your feedback, it help us to do better in the future. We will show you some design idea in Qixi: First, the classic relay part, please have a look at every puzzle's clues, they're from 20 to 27. but when solve them, you will find they become more and more difficult. In many people's concept, more clues mean much easier. In fact, count of clues and difficulty are not equal. We don't tell you the correct position of every stick digit, but you can determine them by logic. There are many players become puzzle designer, and the process of determine stick digit is also a design, no matter if you had tried design a sudoku, in this test, you had tried. Fulfill the puzzle, then solve it. That's why many players like the classic part. And we also do some thing about this: if you put digits to the wrong place, you will find no solution for the puzzle, or if you haven't decide all marked cells, you will find multiple solution. To the puzzles themselves(i mean when you put all stick digits in right place), when solve P01 from 1 to 9, you can get all 1, then all 2...all 9, maybe you never find solving sudoku is so happy. P02 - P06 are puzzles can be solved only by singles, but we make them difficulty in observing. P07 - P08 need intersection, pairs and x-wing, they are all basic advance techniques. To variants match part, at first you will find that you can't solve any number by clues, it's like mock test 11 last year. Then you must determine every situation's rule first, it's mostly like a sudoku, and hints are from eight situation. We make a diagram for you:  (They are all from clues, no guessing or trying to solve one situation for finding a mistake.) There is a trap in P09, you can try to solve it by diagnol, it has unique solution, but it's a very tough puzzle and you will find another situation don't have rule to correspond. P13 and P15 have the same pattern, it's only for fun :-) By previous 16 puzzles effort, a "heart" bridge is built. In this twins suoku, you can only solve few cells in single grid, but when make them together(same meaning of "17" in Chinese), can be solved by single. It also means one need to support others. At the end, thanks for LogicMastersIndia give us the chance, and all you spend the wonderful Qixi time together. TTHsieh&Leafcard | ||

Mean Minis (2020) Author Posts: 774 Location: India | MinFang Lin: If you could give a few starting steps on the diagonal (without trial/error), that'd be helpful. I am stuck at the beginning itself | ||

 Diagonal Vision Author Posts: 337 Location: Switzerland | Thanks for this wonderful tournament, I've just finished to solve grids (I redo the entire relay as it was a catastroph during Test). About my test: I did wonderful stupid mistakes on part I (relay): Bad report of relay numbers between puzzle 1 and puzzle 2 (I lost about 10 minutes at the very beginning of the test  ). On another relay puzzle, I copy numbers on cells with grey circles instead of cells with white circles  . After 1h10 and finally 7 relay puzzles laboriously finished, I begin "match maker part", it was fun and I manage to solve 5 grids in about 35 minutes (with one mistype - a single digit  - on the antiknight), which is quite good, I think. Then during the last minutes I try to solve the last relay puzzle, with no success  . After the test, I finish "match maker part". It was really fun and very good grids. Diagonal was very tough, perhaps too much for this 2h tournament. grids 17 were fun, too ! I think, inversely to "sampler platter", it was a little bit too difficult for a 2h tournament. Relay are always a trap because you can't do mistakes, otherwise it spreads on next puzzle and you are blocked on every other grids. Perhaps a 6-grids relay and easier diagonal grid on match maker would have been more balanced for a 2h tournament. However, it was a very good test with very good grids ! Thanks ! Fred | ||

Posts: 83 Location: Czech Republic | rakesh_rai - 2010-08-17 6:36 PM I am stuck at the beginning itself Transfer square No.16 (row 4, column 5 in the diaonal puzzle) has only possible digits 2,5,7. Look at final twin puzzle, transfer clues 1 and 14 are digits 7 and 2. So transfer clue 16 has to be 5 and transfer clue 15 is 8 (only possible 8 in irregular shape) When you add these two digits, diagonal puzzle is easy to complete  Of course, this trick is possible only if you already solve some others matchmaker puzzles before diagonal.
