Now that we have 5 Sudoku Monthly tests over, we'll soon be publishing a Rating System which will provide a Rating for each player. It will consider several parameters, including
  • player's performance in each test
  • number of tests player has participated or missed
  • player's recent performances


  • A similar Ranking for puzzles will be published after we complete 4/5 puzzle tests.

    Little delayed - but better than never.

    Here it is LMI Sudoku Ratings

    Note that the rating system is based on last 5 monthly Sudoku Tests. We'll re-look at the system around beginning of 2011, when we would have more number of tests concluded.

    Many thanks to Neeraj, Rakesh and Rohan (in alphabetical order :-)
    They had spent lot of time discussing about the whole system, many arguments and counter arguments.

    Also, for authors/testers, I think NumTests should include the tests they authored/tested.
    For calculations, it should be ignored.

    If its too cumbersome, scrap.

    LMI Sudoku Ratings have now been updated after the Renban Group Sudokus.... A direct link to the ratings is also included on the main forum page through an icon at the top (next to Authors).

    A total of 237 players (an increase of 31 players) from 38 countries (an increase of 6 countries) are represented in the current ratings.

    Thomas Snyder, two time world champion has comfortably retained his number one spot (despite missing the Renban Groups)and Nikola has jumped to the second spot pushing Jason V Zuffranieri down to the third spot by just a single point margin.....really a tough fight. Chen Cen needs to put some more effort and wait till the next game to come back in the top three..........

    Coming to the Indian participants.........No change in the top two Indian positions but Rohan slipped to overall 10th slot from his previous 9th while Rishi improved his rating and reached to the 7th from 8th position. Gaurav Korde has been dropped from the ratings as he consecutively missed the third test....and thus Jaipal joins Rishi and Rohan in the top three Indian positions. Both Rishi and Rohan need to work hard for coming in the elite top 5....

    Do share your comments on the ratings here.

    The rating is calculated based on a scientific algorithm (and very difficult to explain here), which uses multiple factors (e.g. scores, consistency, # of tests). The maximum possible rating is 1000 and the minimum is 0.


    Best way to come up in the ratings is to keep on playing regularly (dont miss the tests) and try and do well........

    It would be nice if you add points change (for ex. +16) in comparison with score from previous leaderboard.
    And similar statistic for player position change :)

    Just a proposition for the rating:

    It would be interesting to indicate (perhaps with arrows next to the ranking) if the rank of a player is better, worse or equal compared to last ranking (ranking before last test).

    Wasn't exactly aware there was a rating system. Guess doing a 100 min. test in 50 minutes isn't exactly good for that. At least I should be able to go up with the next test?

    Akash: As Neeraj metioned, there is a currently an algorithm in place for ratings. And, we'll re-look at it periodically, to improve it further. The next review should happen around early 2011. So, if you do have any points/concerns, please share them here, so that we can discuss them while reviewing, and include any valid ones.

    And, Congratulations for improving your rating by 160 points !!!

    Both are valid points. This is very much a part of the plans, and you'll see this happen sooner than later.

    Fortunately, the next puzzle test (FLIP) is for 50 mins duration only :)

    At least I should be able to go up with the next test?
    I think your LMI sudoku rating should defintely improve with a reasonable performance in the next LMI sudoku test.

    And, the LMI puzzle ratings will also be coming up soon.

    50 minutes for a test is an exception.
    Most Sudoku tests will be between 100 to 120 minutes (ideally 120 minutes)
    Most puzzles tests will be between 80 to 120 minutes (ideally 100+ minutes)

    it was a pleasant surprise to see my ratings increase by 160 points. wasnt actually expecting it to improve as much as it did. i guess 360 points is not bad for someone with just two monthly tests under his belt.
