Mean Minis (2020) Author Posts: 774 Location: India | akash.doulani - 2011-01-14 5:59 PMone question regarding tennisdoku. in a situation where the set is given as 1:0 , does the first number have to be greater than the second one or it could be both ways ? Thanks for asking this question, Akash. In a "x:y" situation, x is the number of sets won and y is the number of sets lost. So, a "1:0" means 1 set won and 0 sets lost. And a set can be won in many ways: 6-1, 6-2, 6-3, 6-4, 7-5, 7-6, 8-6 and 9-7. so the two cells in question will have one of these "final scores". To answer your question precisely, the answer is Yes. For a "1:0" situation, the first number has to be greater than the second one. I hope this helps clarify your doubt. | ||

Mean Minis (2020) Author Posts: 774 Location: India | akash.doulani - 2011-01-14 8:25 PM Akash: This is mentioned clearly in the IB. will the clues(i.e the numbers that appear in each type ) be given for poker sudoku or we will have to find out the numbers ourselves? "The repeating number in three of a kind/ four of a kind will be given. For full house, two numbers will be given, one of which will form a “pair” and the other will represent “three of a kind”. For Two pair, again two numbers will be given, both of which will form “pair”. For sequence, the first and last number will be given as clues." So you do not have to find out the numbers. With the given clues, you'll probably need to find out which hand type will be on which line. | ||

Posts: 315 Location: The Netherlands | For Prime Number sudoku, are we provided with a list of prime numbers made up of different digits? Because to be honest I don't know all prime numbers by head between 1 and 9 digits (I don't even know them past 2 digits), or be able to figure out if for example 7142957 (which is) or 7148563(which isn't) is a prime or not on the spot. Becaused the file I found to confirm if these numbers were or weren't, contains 1 million numbers. And I don't exactly feel like sorting through it to filter out all primes that only contain different digits, just for the sake of being able to solve the sudoku. | ||

Odd Even & Twisted Classics (SM 16/17) Author Posts: 460 Location: India | In the Numerologidoku, can the resultant number be flipped. as in example you mentioned that when I add up the letters I get 63. So is only 63 to be used or it can be flipped to 36? Rishi | ||

Mean Minis (2020) Author Posts: 774 Location: India | purifire - 2011-01-16 12:02 PM Rishi: Flipping is not allowed. (also because this is not the FLIP LMI Test )In the Numerologidoku, can the resultant number be flipped. as in example you mentioned that when I add up the letters I get 63. So is only 63 to be used or it can be flipped to 36? As mentioned in the IB, All “clue numbers” in the shaded cells read from left to right. - without flipping. So, if one of the clues is RISHI, we'll have to fill 63 in two consecutive shaded cells in the same row, reading left to right. | ||

Mean Minis (2020) Author Posts: 774 Location: India | Para: I was expecting this query and I'm glad you asked it. Para - 2011-01-16 3:32 AM No.For Prime Number sudoku, are we provided with a list of prime numbers made up of different digits? Because to be honest I don't know all prime numbers by head between 1 and 9 digits (I don't even know them past 2 digits), or be able to figure out if for example 7142957 (which is) or 7148563(which isn't) is a prime or not on the spot. Because the file I found to confirm if these numbers were or weren't, contains 1 million numbers. From the IB: "...prime numbers are like life. They are very logical but you could never work out the rules, even if you spend all your time thinking about them." Anyway, Prime Exotica is not a test of memory. So its perfectly alright if you do not remember a list of prime numbers. However, there are a few basic techniques to find out if a number is not a prime number (for example, one such link is here). You may like to go through these once. And I don't exactly feel like sorting through it to filter out all primes that only contain different digits, just for the sake of being able to solve the sudoku. I agree with you. This is not needed anyway. In my opinion, if you approach the puzzle with an open mind and only basic knowledge of prime numbers, you should be able to solve it. | ||

Mean Minis (2020) Author Posts: 774 Location: India | A feature being tried out this time is that of "anonymous ratings". On the score page, the average rating and number of solvers who rated will still be visible. But A cannot see ratings given by B (and vice-versa). | ||

Posts: 10 Location: India | Rakesh, the moment I started reading first word of IB, it was very much involving and extremely interesting till the end. With my limited exposure to different kinds of puzzles/sudokus, I find these very interesting. Finishing touch (Tennisdoku) is superb. Coincidentally I read this on the day Australian Open began :). Looking forward for the test. | ||

Mean Minis (2020) Author Posts: 774 Location: India | The points for grids are rough indicators of the difficulty level of the grid. However, your experience can vary. For every sudoku grid, exactly 10 cells are marked as answer key. I do hope that you find time to take and enjoy the test over the weekend. In case of any issues during the test, you can send PM/mail to me. (pe.jpg) Attachments ---------------- pe.jpg (43KB - 3 downloads) | ||

Posts: 81 Location: India | Really good set of puzzles..... Had a great time solving them! I personally liked DNA Sudoku best but unfortunately could not submit the answer to it because of lack of few seconds... Kombinance and Kid were enjoyable too... Thanks for the test Rakesh, got to solve some new and really good variants! :) | ||

In product sudoku, you were very close - in fact, you missed entering only one digit in the answer key. Sorry to say that we cannot award any partial marks. | ||

Posts: 148 Location: France | Thanks for this nice test Rakesh. I must admit that I wasn't completely enthousiast about some of the puzzles, which rules did not seem very interesting to me, but you exploited them well and I really had pleasure today. Only 10 puzzles solved out on 13 because of, as usual, lots of mistakes - and also a printing problem. But no big deal, I came for fun and fun was there. See you all on next LMI test, Bastien | ||
