The queen sudoku of diagonal vision's instructions booklet is a bit too hard... It's my fault.
We discussed about it there: http://logicmastersindia.com/forum/forums/thread-view.asp?tid=451&s...

Fred

So i am not the only one stuck it seems! But Beautiful theme nevertheless....similar to what u do in a chess game.......think ahead and see if it is advisable to go with that continuation...perhaps thats why this sudoku is rightly named queen sudoku....i was looking for a logical continuation....did not look for a contradiction at all....

and in symmetric unequal what does cells 180deg symmetric to each other mean..????totally blank....could not make out head or tail out of it...kindly explain guys..

R1C1 is symmetric to R9C9, R1C2 is symmetric to R9C8, R2C1 symmetric to R8C9, etc... does it help?

Fred

So going by the same logic R5C1 is symmetric to R5C9 ,R5C2 is symmetric to R5C8 etc...and the only cell symmetric to itself in the entire grid is R5C5...?!

That is correct. Now all the additional rule says is "If two different cells are 180⁰ symmetric to each other, they must contain different digits".

Kishy: BE CAREFUL NOT TO POST THE SUDOKUS OF A COMPETITION BEFORE IT IS FINISHED !

The competition is now finished, but it was not the case when you posted this one.

That being said, try to place the 2 in row 5, and then you can place lot of other digits

Kishy72, Consider this as your first and last warning. Never post puzzles from LMI / other sites while the competition is running. Always wait for few hours after the competition ends.

This thought did cross to me immediately after i had posted it but i left it at that thinking that the person had just as much a chance of going wrong as getting it correct by seeing this sudoku but anyway i know that that is not the point.It wont occur again.

You could have removed my post instead of admonishing me like this or you could have said to me in private before u posted this.This looks like slapping me in the face and saying 'Dont post sudokus in this forum'.I m not a fugitive under warrant

Well you'll have to be to solve the next test :P Anyway, in all seriousness, what you are doing(posting on forum and asking doubts) is great. In fact we've been encouraging beginners to do that for some time now. Its just that, when something like this happens, we need to make sure it doesn't happen again through anyone, not just you. I think that was the reason for the public warning. Do be careful in the future :)

I can proceed further by seeing that 5 in Row 7 put in either place puts 7 in R7C4, which can be seen using row 4 for one placement of 5, and the other is pretty straightforward. There's another sticking point in proving that R9C2 can't be 4 (4-5 in the 7th box means 5 must be in R4C2, where'll 7 go in C2?). Its pretty difficult, but thats the closest I can come to a solid path.

There's a way to eliminate 4 from R5C6 (It then goes in R7C5 and eliminates both possibilities in column 8!). Also, only 4/8 can be in R9C9 because of R7C5, which means one of 4/8 in Row 7 is in C8/9, so R7C6 is 3/9 only. After that, I could prove that R9C4 cannot be a 3 by just using 3s and 9s and seeing the crowd-out that happens in R1C9. But this last step's bordering on guessing, so I'm not sure if thats the intended path.

I'd wager I've never met a person who can solve that puzzle logically or even deduce 1 digit before guessing. I'd even say I've yet to even find a computer solver that can do it -- One solver completely stopped without any digits and the other required a lot of Bowman's Bingos which are essentially guesses.

You can probably check some of these puzzles out this way too. I recommend plugging them into sudokuwiki.org/sudoku.htm which can quickly evaluate the next step at a point when you get stuck.

Can I ask what book this is that is publishing such crazy puzzles?

I sometimes put sudokus into the solver you recommended. But it still is a computer and some of the strategies are just way over the top and too funky. The last times I posted puzzles in here it was the same way: I first put them into the sudoku solver to see what it had to say, and then I put it in here. I found that the "human solutions" were always better to understand and there were still some nice tricks about it.

Unfortunately, this time I didn't bother to put it into the solver because I was sure it would give me extraordinary strategies I'd never use again.

The book is Nr. 31 from Stefan Heine: http://www.ps-heine.de/archives/1037

With the Sudoku Caravan moving next to the UK and then the US in a short notice i thought it would be appropriate now to get the unworked worked out.So after a bit of an exile from this stuck forum (which was more self imposed) i m back to being stuck again .So this is going to be the first of the three 'Big Fish sudokus' that i m going to post.This movable digits sudoku looked like a fun puzzle to solve until the point i got stuck from where it became suddenly 'immovable' and made me to call it quits.So fellas can you find the continuation and shw the way to me?

To start, look at where the 3 can go in R2. It will give you a few placements. To not ruin the rest of the solve, i'll let you try to solve it from this point. If there's another sticking point, just show where you're at after this.

Hi !!Thnks for the nice tip .I was able to proceed from there till here.I see that this stage is ripe for a bifurcation where the numbers will rapidly fall in place after that but i was looking for the logical continuation and the right line of thinking has eluded me for close to 45mins from this point.How do i continue from here?!

In the upper right region, the 7 is in Row 2 or row 3. There is another 7 in row 2 or row 3 which is neighbour R3C6. R2C3 can't be a 7.

Thnks .But i got stuck again in the same sudoku just after placing the 4s in first 3 rows and 7s in first 2 rows.I am not going to waste everyone's time by posting that sudoku once more.I would greatly appreciate a spoiler though again from that stage.
Time to move on to the next one.I have completed the 108 point killer after a torturous grind.So this little killer would be the last i would be posting from the serb grand prix and i hope that i dont get clueless multiple times just like the previous.Excepting a few deductions i was unable to make much of a start here.Applause to all those who have completed this.

purzelbaumfan Posts: 13 Country : Germany	purzelbaumfan posted @ 2013-04-03 11:33 PM Thank you. I have managed to solve some other puzzles of the "extreme" level. Now I tried a "hardcore" one and I can't get any further. I don't even know where to start a chain! What do you say? Edited by purzelbaumfan 2013-04-03 11:34 PM

motris Posts: 199 Country : United States	motris posted @ 2013-04-04 5:32 AM I'd wager I've never met a person who can solve that puzzle logically or even deduce 1 digit before guessing. I'd even say I've yet to even find a computer solver that can do it -- One solver completely stopped without any digits and the other required a lot of Bowman's Bingos which are essentially guesses. You can probably check some of these puzzles out this way too. I recommend plugging them into sudokuwiki.org/sudoku.htm which can quickly evaluate the next step at a point when you get stuck. Can I ask what book this is that is publishing such crazy puzzles?

purzelbaumfan Posts: 13 Country : Germany	purzelbaumfan posted @ 2013-04-04 8:09 PM I sometimes put sudokus into the solver you recommended. But it still is a computer and some of the strategies are just way over the top and too funky. The last times I posted puzzles in here it was the same way: I first put them into the sudoku solver to see what it had to say, and then I put it in here. I found that the "human solutions" were always better to understand and there were still some nice tricks about it. Unfortunately, this time I didn't bother to put it into the solver because I was sure it would give me extraordinary strategies I'd never use again. The book is Nr. 31 from Stefan Heine: http://www.ps-heine.de/archives/1037

kishy72 Posts: 419 Country : India	kishy72 posted @ 2013-04-25 8:39 PM With the Sudoku Caravan moving next to the UK and then the US in a short notice i thought it would be appropriate now to get the unworked worked out.So after a bit of an exile from this stuck forum (which was more self imposed) i m back to being stuck again .So this is going to be the first of the three 'Big Fish sudokus' that i m going to post.This movable digits sudoku looked like a fun puzzle to solve until the point i got stuck from where it became suddenly 'immovable' and made me to call it quits.So fellas can you find the continuation and shw the way to me?

Para Posts: 315 Country : The Netherlands	Para posted @ 2013-04-25 9:01 PM To start, look at where the 3 can go in R2. It will give you a few placements. To not ruin the rest of the solve, i'll let you try to solve it from this point. If there's another sticking point, just show where you're at after this. Edited by Para 2013-04-25 9:05 PM

kishy72 Posts: 419 Country : India	kishy72 posted @ 2013-04-27 11:25 PM Hi !!Thnks for the nice tip .I was able to proceed from there till here.I see that this stage is ripe for a bifurcation where the numbers will rapidly fall in place after that but i was looking for the logical continuation and the right line of thinking has eluded me for close to 45mins from this point.How do i continue from here?!

caudmont Posts: 18 Country : France	caudmont posted @ 2013-04-28 12:53 AM In the upper right region, the 7 is in Row 2 or row 3. There is another 7 in row 2 or row 3 which is neighbour R3C6. R2C3 can't be a 7. Edited by caudmont 2013-04-28 12:54 AM

kishy72 Posts: 419 Country : India	kishy72 posted @ 2013-05-02 7:04 PM Thnks .But i got stuck again in the same sudoku just after placing the 4s in first 3 rows and 7s in first 2 rows.I am not going to waste everyone's time by posting that sudoku once more.I would greatly appreciate a spoiler though again from that stage. Time to move on to the next one.I have completed the 108 point killer after a torturous grind.So this little killer would be the last i would be posting from the serb grand prix and i hope that i dont get clueless multiple times just like the previous.Excepting a few deductions i was unable to make much of a start here.Applause to all those who have completed this.
