General questions

Sudoku-Forum dmx.27 is a strong contender
The record was broken faster than I expected and by dmx.27. The new record now stands at 58 seconds. Who will break this? Премудрая or wongmc.

Sudoku-Forum Wo sind meine fehlerhaften Spiele ????
Hallo Schurik, danke für die Antwort. Leider kann ich nichts mehr nachprüfen, weil das Spiel komplett weg ist. Ich werde aber heute noch mal Eins probieren und extra falsch abspeichern. Hab die letzten Spiele immer zwischengespeichert und da ging es besser. Liebe Grüße [11 Jun. 2006, Honig-Bienchen]

Sudoku-Forum Welcome to the Sudoku Marathon!
A new mental challenge is already awaiting all players on Play-Sudoku.de : our Sudoku Marathon! Every registered user is allowed to participate, however it is recommended to first carry out a decent Sudoku training before you sign up. We particularly recommend our Sudoku Marathon for quick thinkers who have become a bit bored of our usual brain gymnastics. Our marathon is divided into four parts according to difficulty level: easy, average, difficult and crazy. In order to reach the next level, you must remain within the alloted time limit. This means: * 15 Minutes for an easy Sudoku, * 20 Minutes for an average Sudoku, * 25 Minutes for a difficult Sudoku * and 35 Minutes for a crazy Sudoku. Points will be awarded as usual. For each filled spot on a crazy Sudoku, you will get 5 points. When staying within the time limit, you get an extra point for each unused minute. In order not to overwork your think muscles, you can only run the Marathon once a day. Should you not succeed within the alloted time, you will gain the usual points but not be allowed into the next round. Should you stop midway (for example, by clicking away from the page), you will only be able to try again on the following day. It is impossible to get hints or to save your game while doing the Sudoku Marathon. It's just like a real marathon: you're supposed to run the distance in one shot without stopping. Is that not the perfect challenge for you? [01 Jul. 2006, schurik]

Sudoku-Forum Премудрая - the ultimate solver
How very strange. The users both vote +1 for Премудрая when he reaches -7 (which is quite dangerous :lol: ) and Премудрая just happens to vote +1 for both of them. Coincidence?? [23 Jun. 2006, irkapina]

Solving techniques and solver programs

Sudoku-Forum Can this one be solved without guesswork?
Hi, yes you can solve it without guesswork :P This one is tough indeed. There was a point, where I thought it couldn't go on. Then I saw the numbers 8 and 9 in the 2nd vertical line, which had to be the only numbers in the 3rd vertical line within the 4th and 5th place. So I could put the 6 into the 6th place. ... hmm, I don't quite follow the reasoning. I cannot solve it without guessing, my solver can't solve it without guessing and none of the websolvers I tried can solve it without guessing. I see no logical reason why (in the third column) the 8 and 9 should be in 4th and 5th place (thus positioning the 6). If anybody could explain the logic I 'ld sincerely appreciate it (always ready to learn). [06 Jun. 2006, irkapina]
