I am planning to participate in LMI Sudoku tests first time? What are the guidelines?
1) The first thing you need to do is read the rest of this thread.
2) Download the instruction booklet which is available in pdf format in the test page. Understand all Sudoku rules and practice the examples.
3) Check the forum thread corresponding to the test (click on "Discuss this test" on the test page)
If you still have questions, please post in the thread corresponding to the test.
To participate, you need to be a registered member at LMI. You can go to the LMI monthly Sudoku test page. There are couple of easy steps.
You first need to login. The login screen looks like the image below.
If you are participating in LMI test for the very first time, you also need to fill the country.
You should be able to see a "Start Test" button. Note that this button will be greyed out if the test is yet to start. (Tests usually start at Saturday morning 00:00:01 GMT)
Before clicking on the button, you should unselect "Consider my results for LMI Sudoku Ratings", if you don't want to use this test results for LMI ratings.
When you are ready to take the test, click on "Start Test".
Your timer starts when you click on this button. A password will be shown below the timer. Using this password, you can unlock the Puzzle Booklet.
In most Sudoku tests, there are 2 ways to submit answer.
1) Paper mode : Download the password protected pdf, unlock it using the password, print, and solve on paper. Submit the answer codes using the 'answer form' meant for paper solvers.
2) Online mode : Sudoku grids are also available to be solved online. You can solve and submit online as well.
Note : Some tests may not have online modes. (Effective from May'2011). The information will usually be posted in forum. Please ask in forum, if it is not already posted.
Typically, each Sudoku has 2 answer codes. They could be rows / columns or any combination of them. It will be marked in the pdf. After you solve the sudoku, enter the answer code using the paper form.
Please read the answer codes carefully (preferably before you start the test)
After solving on paper, submit the answer codes for each puzzle you have solved.
After filling your answer, if the text box does not completely turn white, it means answer code has a typo or a formatting error. (i.e. you are entering something unexpected and there is an error in your answer code)
Please fix it before submitting. Even if red warnings are present, your submission will be recorded after you click on Submit button.
Also, note that if a text box doesn't have red warning next to it, that doesn't mean the puzzle is correct.
If you scroll down below the 'paper form', you would see flash for the Sudoku grids which can be solved online.
This has basic features like pencil marks, undo, coloring.
It is important that you get familiar with LMI flash if you are planning to use it during the test.
[ One note : To remove a pencil mark, you can "Control+left mouse click" on the number OR press "Control+digit" in the keyboard ]
Each Sudoku has a submit button. Click on Submit as soon as you are complete.
Paper Vs Online
We don't recommend which mode to use. You must decide that yourself (depending upon factors like printer availability, type/size of Sudoku etc)
Even you might decide to solve some sudokus in paper mode and some using online.
Submissions via email or any other means will not be accepted.
When do I click submit button? Can I click submit button multiple times?
You can click Submit button as many times as you want. You last recorded answer for every sudoku (either from online or paper mode) will be considered for scoring.
You should adopt a submission method that is most suitable for you. For example, you might (solve one sudoku and submit) OR (solve couple of sudokus and submit) OR (solve all sudokus and submit at the end).
If you are solving online, you don't need to again submit using paper mode. It is timing consuming and error-prone
If you are participating for first time, we would recommend that you submit every half an hour or so. It is important to know how much time you take for entering the answer codes. There is nothing worse than solving a sudoku correctly on paper, but not being able to enter the answer code because of lack of time.
Also note that we store individual submission time for each sudoku. In all tests same scores are sorted by last sudoku timestamp. So it is not a bad idea to submit all your solved sudokus 10 or 15 minutes before your timer ends.
At this point, LMI doesn't use a "grace period" concept. It is absolutely left to you to submit all sudokus before your timer ends.
In Jun'2011, LMI introduced something called "Claim Bonus". This equivalent to "turning in your paper after completing all puzzles" in an offline event. This button is placed next to "Submit" button.
Most LMI tests are designed such that top solvers are expected to solve all puzzles within the time limit. Therefore every test has a "time bonus" which is awarded if all puzzles are solved before time. Typically the "time bonus" per minute is around "total points in the test" / "length of the test".
As soon as you complete and submit all sudokus, you should "Claim Bonus". It is not a bad idea to check all submissions once because you can no more submit or change your answer after you claim bonus. Bonus points are computed from the time when you "Claim Bonus", not from the time when you last submitted your answer.
Also note that "Claim Bonus" also submits all answers those are not submitted. So, if you want to save few seconds after entering all your answers, you can directly click on "Claim Bonus" button.
Some tests have "partial bonus points". This is awarded when the player submits all sudokus, but one of them is wrong. Administrators and test authors reserve the right to determine if the player has made a genuine attempt at the sudoku. If they believe so, partial bonus points are given (which is much less that 'full' bonus points)
I have completed the test. How do I know my score?
The link to score page is available at the test submission page.
Note that while the test is running
1) you can view the score page from the same browser you took the test from
2) you can see only your submitted answers.
3) in most cases, you should be able to see others' overall score (no breakdown)
4) you can not refresh the score page more than once in a 30 minutes time period
LMI likes to experiment with the score pages, and so in some tests you might notice some oddities :-) Typically they are not 'bugs', however if you believe that something is definitely wrong, please post in forum.
After the test is over
1) you can see everyone else's submitted answers and time of submission
2) you can see correct answer for every puzzle
3) there is no restriction on refresh time (though the score page is unlikely to change anyway)
I made an obvious typo while submitting. Can I get points for that?
In most Sudokus tests, claims are allowed only for typos for cells with given clues. If there is no "online solving mode" for the Sudoku test, we might be more lenient.
Claims are made from the score page. Click on the "Claim Points" button for the respective sudoku and leave a short message for the organizers to check your claim
Organizers and authors review all claims from time to time during the test. If your claim is successful, you would see points for the puzzle. Otherwise, you would see an 'X'.
Most of times, you would receive a PM in your forum inbox regarding your claim.
1) Organizers and authors have to convince themselves that the claim can be awarded. We've seen in the past that most claims are unsuccessful :-(
2) Irrespective of whether you claim or not, all wrong submissions are reviewed before the score page is made public.
3) Claims will not be allowed after the score page is made public.
What software do I need on my machine to be able to participate in LMI tests?
You need 2 different software.
Adobe Acrobat Reader - This is needed to open pdf (Portable Document format) files.
Instructions Booklet and Puzzle Booklet are always uploaded using this format.
It is important that you have some recent version of acrobat reader.
Adobe Flash Player - This is needed to login and submit in the test page.
Unlike other sites, LMI uses Flash player for submission and score page for several reasons.
It is important that you have latest version of Flash Player.
In most computers these 2 are already installed. Unless you are using a brand new computer, you are all set to participate.
Since you are able to read this page, you definitely are using some browser. It is always good to have the latest version of that browser installed.
LMI does not use any browser specific mechanism, however LMI web pages (forum and test pages) look best using Google Chrome and Mozilla Firefox.
I see from score page that sudokus are rated. How do I rate sudokus?
Sudokus can be rated from the test submission page. Rating stars are available below each sudoku. Click on the star to rate the sudokus. (More stars means better puzzle)
There is no submit button, just clicking on the star is enough. If you've rated a puzzle, the stars will have a different color.
Authors look forward to any kind of feedback regarding the sudokus. It is nice to rate the sudokus. [But please don't experiment with the stars - we have seen that some players just click on the stars for fun. It is not advisable ]
It is not necessary to rate the sudokus while the timer is on. In fact, we recommend that you rate the sudokus only after you finish the test.
Starting Jan'2011, the ratings are made anonymous (that means no player can see what other player has rated)
is this game online or offline(8*8 sudoku 12 to 14 may)?
There is no online solving for this test.
You will need to download the Puzzle PDFs on the test page (http://logicmastersindia.com/M201205S/), then start either Part to get its password, unlock the PDF, and solve the puzzles either on computer using some Paint-like software or take a printout and solve on paper. Read the Instruction Booklet for how to enter answers and all, also on the link.
the instruction manual for 2013 ISC shows the start time to be 1400 hrs IST. but here it shows to be 00:01 hrs GMT. what time do we expct the test to be uploaded?
Hi. This is the general F.A.Q. that deals mainly with the monthly tests. The ISC is a bit of a special test because it is a national championship and so it will be at 1400 hrs IST as mentioned on the submission page. The details above are mainly an effective way to learn how to use the site, participate in the contests, and use the interface.
plz would u tell me how to submit the code while starting
Once you start there will be a bunch of submission boxes appearing. Its not exactly the same but check the IPC Demo page we set up for the Indian Puzzle Championship earlier. The submission boxes will similarly appear once you login and click start. The only difference is there will be a submission button below each Sudoku name to let you submit and let you know immediately if its right or wrong.
If you meant what codes to enter, each Sudoku will have 2 arrows outside the grid, A and B. Each Sudoku will contain 2 boxes on the submission page. Enter the 9 digits along the row/column A in the top box and the 9 digits along row/column B in the bottom box.
Do you provide any orientation classes or training classes for students? if yes, when and where?
Sorry but no. However, I recommend just asking your queries on the forum and being regular on contests. For one thing, these kind of puzzles and Sudoku variants are easier to get used to with interaction and regular solving, and for another you will potentially get responses from some of the world's best solvers :) You may score low on contests at the start, but that is completely fine, we've all been there.
Will Claim Bonus gives us extra time only for offline puzzle solver, or it is such that if we do sudoku earlier, it will benefit us next round?
Claim bonus is applicable only in fixed time contests without instant grading. In this case, if a solver finishes all puzzles before time, they may click the claim bonus button to signal that the test is over, and at this point bonus will be calculated according to correctness of submissions for that contest only.
