I'm sure they have lot of time designing the Sudokus (e.g. in all MatchMaker puzzles it was not possible to solve a single digit without determining its type) [ That probably made it tough :-) and Niulang and Zhinv could not meet ) 2:30 hours test would have ensured that at least a couple, if not many, players would have got the bonus points. Thank you again. |

[ Interesting that zorko has submitted only one classic ] janoslaw got 7 correct. 4 more got 6 correct. As many as 29 players got all Classics correct.

Posts: 774 ![]() ![]() ![]() ![]() ![]() ![]() Country : India | rakesh_rai posted @ 2010-08-17 10:47 AM Thanks Deb. So, most participants did not get enough time for matchmakers as only 56 participants got points as against 101 in classics.The testing of the sudokus and the duration of the test could have been better designed. For example, diagonal, touchy, and no three odd/even could have had more points than the rest of the variants. Also, having the test for 2.5 hours is not correct (its too long). We could have dropped one classic and one variation perhaps for a 2 hr test. |

Posts: 103 ![]() Country : Serbia | Nikola posted @ 2010-08-17 12:11 PM Wonderful sudoku test, congratulations for organizers and all toppers! Classic sudokus are my old complaint, but I think this time I chose the wrong tactics. I have the same number of performed puzzles as Jakub and Thomas, and look at the difference! I solved all matchmaker in about 85 minutes and the rest of time did only 6 classics. |

Posts: 40 ![]() ![]() Country : China | Minfang Lin posted @ 2010-08-17 5:19 PM To luckypunk: you can search "intersection, pairs, x-wing" by google. To rakesh_rai: diagonal, touchy and no 3 odd/even in line are most difficult in variants part, both the puzzle itself and determining the rule. But if one solved as the order we show, he can complete at least 5/8. Are there someone need help with the puzzles? Please let us know. All puzzles can be solved by logic. |

![]() Posts: 337 ![]() ![]() ![]() ![]() Country : Switzerland | Fred76 posted @ 2010-08-17 7:03 PM 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 ![]() ![]() 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 ![]() ![]() 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 |

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.

Should they not be classified according to the time resolution? Good point Fred. Not sure if we should change anything for this test, because we didn't annouce anything before the test. But in future we must introduce tie-breaker rules. If others think that we should break the ties based on submission time, we can try to that for this test itself. |

Posts: 40 ![]() ![]() Country : China | Minfang Lin posted @ 2010-08-17 7:59 PM The first step of diagonal: ![]() See D\ only two place can be 7 (r1c1 and r5c5), so r1c9 and r9c1 can't be 7. Then check D/ only one cell can be 7, it's r5c5. |

Posts: 40 ![]() ![]() Country : China | Minfang Lin posted @ 2010-08-17 8:18 PM The technique is called crossover. You can learn it from http://www.sudopedia.org/wiki/Crossover or search it by google. Any other question? |
