That means, a player who finishes all puzzles within the time limit is solving at the speed of at least 6-7 (and maybe more) points per minute, whereas the time bonus is just 3 points per minute. I think the time bonus should be increased. In particular, players completing Part A and Part B would be solving at a speed greater than 5.5 points per minute and 7 points per minute respectively. The time bonus of 3 points per minute looks meager and will surely not give a good indication of the different of performances of players who complete the test before time. Obvious Issue: Players completing Part B should be given a higher time bonus than those completing Part A. |

If you have in one row numbers "213..." the first visible odd skyscraper is 3, because 1 is covered by 2. Ok. I get it. The example doesn't have any such case, so it was misleading. Thanks. It did have a few examples I think, not exactly like the 213, but skyscraper logic was required. The "2" below R6C5 had to be satisfied in the first cell itself, since the 5 would block vision towards the 2. This is not the case in Even Odd View I guess, you could've had 5 in the first cell and 2 in the next with the "2" outside clue. (I'm saying this with memory of solving yesterday, so the placements may be a bit off, but the logic was there) |

In the IB, you should aply both rules at once - in region with 6 cells no digits may repeat and each digit should appear at least once. |

How do I have to see this? Thanks in advance! Best regards, Richard It is just a IB. We were not able to construct 28 original 8x8 puzzles for Instruction booklet. We believe, that for understanding the rules/instructions it is enough to have smaller puzzles in IB. And also, it is not possible to rotate half of the rectangles in 6x6 puzzle as in 8x8 puzzle (see the classics A1-2 and B1-2 in the IB). |

I just wondered if more grids would have irregular shapes than the presented puzzles in B1-2, B4, B5, B6, B11 and B12. I know how much work it is preparing a test plus IB. Having no less than 28 puzzles (x2) isn't making this easier! I am looking forward to the test, since 14 puzzles for a bit over an hour seems like that there are a few quickies to be done, even for a midrange-solver like me. ![]() |

Some of the puzzles will be easier (it is not hard to discover which ones), so that is why we even haven´t tought about bigger (harder) puzzles in IB. And of course, we want to keep the best puzzles for the competition. All the irregular puzzles (as Irregular sudoku, Surplus-deficit or Irregular without regions) are irregular in IB. Only the usual variants, which will have rotated regions, are unrotated in the IB. |

Posts: 164 ![]() ![]() ![]() ![]() Country : Slovakia | greenhorn posted @ 2012-05-10 12:20 AM Dear puzzle friends, in Foursome sudoku (A11-14) there are four sudoku grids and the points may be distributed for each grid independently. However we accept only solution, that is valid for all four puzzle grids together! This sentence is missing in the IB, but we believe, that it was clear also before. Thank you for understanding!

Posts: 31 ![]() Country : United States | joshuazucker posted @ 2012-05-13 8:44 AM Wow, lots of fun puzzles, thanks! I'm pleased that I turned one in with about 30 seconds left on the clock in part B. I hope I got it right. One small correction, perhaps: It seemed like several times the input instructions said "row" when they meant "column" based on what was drawn on the paper. |
