Beginners' Contests changes


1. Instant Grading
=============
Instant Grading will be enabled in Beginners' contests. Upon submitting, either with paper mode or online mode, you will immediately know if the submission is correct or not. Each wrong submission will be penalized by adding 1 minute to your submission time. There will not be any deduction of points.

2. Extended Time
=============
To encourage players to solve and submit all Sudokus, players can now submit Sudokus even after the initial 40 minutes is over. However, sudokus submitted after 40 minutes will get only 50% of the points for the corresponding sudoku. Note that the timer will now start from 00:00, running up.

3. Score Page
==========
Score page can be viewed anytime after you submit your first sudoku correctly. However, you cannot see others' submissions for sudokus you have not solved correctly. As usual, score page can be refreshed only once in 30 minutes. Also, there are few changes in terms of the default score page view.

The regions 'wrap' around the grid. For example: R1C1, R1C2, R2C1, R6C1, R6C2, R7C1, R7C2 is one region of seven cells.
Wherever there is no thick border at an edge, it means the region continues to the opposite end. Look at the 5 at R2C3 and the 4 at R7C4, they lie in the same region.

In Irregular Sudoku, there is no 'wrapping' in the regions.

Re : Beginners' Contests changes


Just a clarification about extended time, this time will run till Beginners' contest is over, i.e. 17th October in this case.

No Penalty award



In case a participant has submitted without entering the required number of digits, or only entered one half of the key, that participant will be awarded no penalty for that submission. However, this change needs to be manual from our end so the change may not occur immediately.

Thanks for another good beginner's contest. The half credit for late submissions to encourage everyone to work all puzzles is an excellent idea.

Congrats to hjkl18(Czech Republic), momiji(China) and mtgs(UK) for topping Beginners' Contest October. Among Seasoners, F4han(Malaysia), jaku111(Czech Republic) and janoslaw(Poland) top the standings.

Out of 116 Beginners, 102 solved at least one sudoku correctly, and the corresponding numbers for Seasoners is 156/164. Its pleasing to see so many non-zero scores, as that was the main aim with the extended time idea. We have received some good feedback on this, including a comment above, but we welcome more feedback on this and any other aspect of this month's contest.

Thank you all for participating!

Something I'd like to add separately -

There has been some curiosity about the author of these contests. The author so far, barring the one noted here, has been Deb. But, we encourage other authors to contribute too. Obviously, by now, the difficulty expected in these contests is known. The technicalities are -
1. These authors won't be added/updated on the author's page, but they will be given credit on this topic.
2. If at all someone would like to author a Beginners' contest, contact me/Deb and we will let you know the variants for that particular month.

We're pleased to announce that Fred Stalder(Fred76) has already offered to author Beginners' Contest November.

what makes a person disqualified ?i see a person disqualified in the list...what might be the reason?pardon me if i m touching on sensitive topics..but i m curious ..apart from posting ridiculous times like 0:01 for solving all sudokus which happened in the previous month ,does solving all in under 15 or so min warrant a disqualification just because the person might be a beginner?

It is always a difficult decision to disqualify anyone, beginner or seasoner. We discuss it multiple times internally before finalizing anything. I'm not going to share those most-difficult-part-of-administering-online-puzzle-tests here. But "solving under 15 minutes" is not a criteria to disqualify anyone.

Since you are curious, I'll send you an PM regarding why we had a disqualified player this time.

We're pleased to announce that Fred Stalder(Fred76) has already offered to author Beginners' Contest November.


If you're friendly with me, there is a chance that sudokus will be easier than those in the "Diagonal Vision" test.





Haha, I'm joking, of course ! I'm glad to have the honor of creating the grids for the next beginners contest !

There is a small change in image format for the Consecutive Sudoku that appeared last month. Instead of dots, bars will be present between consecutive digits.

I just registered on the LMI site. Could you please tell me where do I get puzzles to practice for this month's beginner's challenge.



Also, could you please share any link on the format how this tournament will be conducted.



I am sure this must be there on the site but being a newbie I am not sure where it is.

For practice you can view the previous Beginners' Contests here - http://logicmastersindia.com/BeginnersSudoku/?test=B201210 . The new types, Outside and No Knight Step(or Anti Knight), can be found, along with other variants if you look through the Monthly Tests, or go to the blogs/sites provided on the links page - http://logicmastersindia.com/home/?g=links . Out of the sites Fed Sudoku, Sudoku Cup and Argio Logic have online solving.

As for format, once the contest page link is shared, there will be a section there giving details of how to use the interface/make submissions. The basic summary is -

You have 40 minutes of "official time", during which you can either download and print a PDF, solve on paper and submit the rows or columns that the arrows show, or you can solve online itself. With each submission the Instant Grading will let you know if you're right or wrong. If wrong, you can re submit but you'll get a penalty of 1 minute added to your time taken for each wrong submission. You may submit after the 40 minutes are done till the contest dates are over, but you will get just 50 % of the points then.

It looks like some players, especially the ones solving on paper, are submitting all Sudokus at the end. Please remember that the points are halved after 40 minutes. So if you have solved some sudokus before 40 minutes, it is important to submit them before the 'penalty period' starts.
