Posts: 235 Country : Russia | Riad Khanmagomedov posted @ 2019-04-05 2:11 PM anurag - 2019-04-04 11:47 PM ROFL.. you are right. That's a print error. Perhaps it was intended like this: the closing pipe comes after the third 'r'. |R-r-r| + C-c-c| There is no printer error. Some of the puzzles I've made in 2015 and corrected in 2019. I modified the problem, but the expression is correct. |

Posts: 136 Country : India | anurag posted @ 2019-04-05 2:38 PM Strange. Are you saying sub-zero scores are valid and considered as more rewarding than a score of 0? |

Posts: 187 Country : New Zealand | kiwijam posted @ 2019-04-05 3:13 PM Anurag, please show respect to Riad, I'm much enjoying the effort he has done for this competition. I think the Magic Tapa expression is clear and makes sense as it is (range minus minimum). As he says, you can maximize whatever you like but the final scores will be based on the official expression. And yes, a score of -1 would be better than a score of 0 if you can achieve that. If there are other negative scores then the most negative score would be the best. |

Posts: 67 Country : France | Puzlifouk posted @ 2019-04-05 4:45 PM I do not know what "score" you are talking about when you say "And yes, a score of -1 would be better than a score of 0 if you can achieve that. If there are other negative scores then the most negative score would be the best." If the score is the final score to maximize (that is | R-r | -r + | C-c | -c), then personally I have never seen that -1> 0 nor -10 > -5 !?! ... But you are free: as you say the expression is clear, everybody will interpret as he wants. |

Posts: 136 Country : India | anurag posted @ 2019-04-05 5:13 PM That's Correct and clears the doubt, at least for some. The whole purpose of asking questions is to be able to complete the set and I am sure puzzle solving is not an objectionable activity. For any unrelated suggestions/objections, I believe personal emails are a better medium. |

Posts: 8 Country : South Korea | 3strikerz posted @ 2019-04-05 6:39 PM anurag - 2019-04-03 11:06 PM Ships: As it is not mentioned on the file, I assume the fragments are pulled out straight without rotation and can be put back the same way as they are. Also, the column clues consider all 10 cells and not just the 5-cell strip. Probably everyone might have understood the puzzle description, but since I didn't and need some clarification; A)Is the red clues in the 5x10 fragments intended to be solved as 5x10 battleship clues, or is the red clues the equivalent of 10x10 original battleship clues? B)Is it okay for ships to be 'fragmented' in the 5x10 clues? |

Posts: 235 Country : Russia | Riad Khanmagomedov posted @ 2019-04-05 7:19 PM In puzzle 11, I will remove the brackets, if it is principled. Minimize the expression R – 2r + C – 2c. James rightly noted that the minimum can be negative. In puzzle 7, the red clues extend to 10 cells. Edited by Riad Khanmagomedov 2019-04-05 7:20 PM |

Posts: 11 Country : United States | randomperson1729 posted @ 2019-04-05 9:36 PM I have a question about "at the levers." If two digits are on one side of the balance, is each one multiplied by its distance from the balance? So if there are two digits next to each other on the pivot, with the closest one unit away from the pivot, would the total for that side be thw closer digit plus twice the outer digit? |

Posts: 4 Country : France | Badacoin posted @ 2019-04-07 3:13 PM I'd like some clarification about Dice Masyu. What happens when you place a dice on top of an existing circle? Must the position of the existing circle match the position of a circle on the dice? Do all existing circles in the grid belong to a dice?

Posts: 11 Country : United States | Eugene Porter posted @ 2019-04-08 6:22 AM Hi there I am enjoying your contest. It is very well done. I do have a question about Dice Maysu. If you cover an existing circle with a half domino is it still 'seen'? For example, if one were to place a domino of six such that a pre-existing circle would be the middle of that six after placement --- would the middle circle be covered ? Would the circle be 'in play' along with the rest of the domino ? Or would one not be allowed to place a domino of 6 in such a location? Thanks -E |

Posts: 187 Country : New Zealand | kiwijam posted @ 2019-04-08 10:40 AM In Dice Masyu, every given circle must match a half-domino circle. e.g. You cannot place a 6-domino such that the centre cell of the 6 covers an existing circle. And you cannot have an existing circle with no half-domino covering it. |
