Location: India | 2016 Points Structure1) Fixed points (50) if the puzzle is solved. 2) Variable Bonus points if the puzzle is solved within 60 minutes. 3) No bonus points if solved after 60 minutes. 3) A player's bonus is dependent on his Rank and on his solving time. DETAILS ======= There are 3 score components if a puzzle is solved correctly. 1) Fixed: 50 points (the player will get this even if the puzzle is started on 1st and finished on 12th) 2) Rank Bonus for top 50 players The top ranked player for the particular puzzle gets 25 points. Next best players will get 24.5, 24.0, 23.5, 23.0, ..., 0.5 More than 50 players are expected to solve each puzzle within 60 minutes. However, if less than 50 players solve any puzzle within 60 minutes, only those players will get rank bonus. 3) Solving Time Bonus The best player for the particular puzzle gets 25 points. Lets say best solving time is B and Median solving time (of all players solving within 60 minutes) is M. If a player's solving time is <= M, he will get 12.5 + 12.5 * ( M - player's solving time ) / (M - B) [A linear distribution from 25 to 12.5 between the best player and the player with median time] If a player's solving time is > M, he will get 12.5 - 12.5 * ( player's solving time - M ) / (60 minutes - M) [A linear distribution from 12.5 and 0 between the player with median time and 60 minutes]. Minimum solving time bonus point will be 0.50, even if someone solves in exactly 60 minutes. | ||

Posts: 45 Location: India | In Pentopia, what do the clues indicate? Actually, I didn't understand "the direction(s) of the closest pentomino(s) when looking from that cell". | ||

Bram has lot of practice puzzles for Pentopia on his blog.In Pentopia, what do the clues indicate? Actually, I didn't understand "the direction(s) of the closest pentomino(s) when looking from that cell". | ||

I am sorry that I am not able to get what you mean by the 2x2 rule ?! There is no mention of it in the rules of the IB and why is his solution wrong ? In the highlighted boxes , I see four different letters in all rows and columns .Why have you highlighted that as an error ?? | ||

Right, it is Sudoku, not Latin Square. As mentioned in the IB, you need to put different digits in "every row, column and outlined block". The outlined blocks are 2X2 in this example. In the competition puzzle they could be 2X3 or 3X2 blocks. May be you guys missed the outlined blocks because of the grey borders in the example. We will make the borders black in the competition puzzle. | ||

Location: India | forcolin - 2016-03-29 4:35 PM When entering the coordinates of the cells in TWIN CO-ORDINATES, is there any particular order/format we must follow? Order does not matter. We expect players to enter like J2 (i.e. first the letter and then the digit). You have to strictly follow the letters/digits given around the grid to determine the co-ordinate. There will be as many boxes as number of pairs. In each box, enter the co-ordinate of any cell in the pair. | ||

For the example puzzle, any of the following keys will be accepted forcolin - 2016-03-29 4:35 PM When entering the coordinates of the cells in TWIN CO-ORDINATES, is there any particular order/format we must follow? Order does not matter. J2, J4 H1, J4 J2, I6 H1, I6 J4, J2 J4, H1 I6, J2 I6, H1 | ||

Diagonal Vision Author Posts: 337 Location: Switzerland | Right, it is Sudoku, not Latin Square. I'm happy to hear that sudoku and latin squares became different again in 2016. | ||

The submission page will accept any 5 pairs. Players should submit as soon as they find 5 pairs.Instructions Booklet is updated accordingly. | ||

Posts: 8 Location: Germany | I still see no chance to get into one of the word search sudoku examples. Could anyone give me a hint how to start, maybe which word can be placed first? In the big one, I only got the "trivial" mini-sudoku-conclusions. In the 9x9 one, I only saw that "mocktest" has 3 possible positions and "sudokus" about 10 (I counted both directions seperate), both of course diagonal. Thank you...

Posts: 315 Location: The Netherlands | For the big puzzle, are you remembering that the whole grid is also a Latin Square? You should be able to assign all letters to the grids at which point the word search starts. | ||

Posts: 8 Location: Germany | Yes, I know for every 4x4 sudoku, which four letters it contains. But after this, now I have to find a word which has only one possible place, or something like that, I think? And this is the point were I can't find something to go on. | ||

Classics & Regions (PR 2016/17) Author Posts: 170 Location: Germany | SilBer - 2016-03-31 12:39 AM Yes, I know for every 4x4 sudoku, which four letters it contains. But after this, now I have to find a word which has only one possible place, or something like that, I think? And this is the point were I can't find something to go on. For example, there's just one way to place NORTH (and to get there, only one pair of 4x4 boxes with N and H where you can find ORT between them). It helps to write down a 3x3 grid with the letters per box. Edited by rob 2016-03-31 2:07 AM | ||
