Is it allowed to make the crossings on the cells with the letters? In that case, if the letter has remained out of the loop, is it an empty cell? The line should pass through each letter. The letter can not be remained out of the loop. |

Is it allowed to make the crossings on the cells with the letters? In that case, if the letter has remained out of the loop, is it an empty cell? I have the same question. For example, along the line we must go through two letters 'A' : is it possible to go through the same letter 'A' 2 times (by crossing), and to avoid the second letter 'A' ? Perhaps such conditions would make the puzzle more difficult. But I assumed that the line goes through all the characters. |

Posts: 145 ![]() ![]() ![]() Country : France | auroux posted @ 2015-04-06 6:25 AM In the answering form, for puzzle 11, I think the answer keys need to be of length 11 not 10 as claimed by the format verification code (which warns me that my answer keys are not of the right length). (In general, many of the answer keys seem trickier than necessary -- really, counting the C's? diagonals that go in the opposite of the usual direction? --, but it's too late to change them). |

I'm a pronounced left-handed. Maybe because I offered unusual diagonals? |

Posts: 4 Country : The Netherlands | Eisbaer posted @ 2015-04-09 5:11 PM I have a little question about puzzle 10... In the requested sentence there are two "I' 's and one time the digit 1. But it looks like there are three same characters "I" (or 1?) in the grid? Could all three characters be used for the digit 1? |

Posts: 145 ![]() ![]() ![]() Country : France | auroux posted @ 2015-04-09 10:25 PM Just to make sure -- in "Tools", the answer key only describes whether the edges of the grid along the given row or column are occupied (and if so by what tool) or not, correct? More precisely: what would be the answer key for the second row in the example? Am I right that it would be -----HH---- ? (i.e. the edges that are "inside" the ladder are unoccupied and so remain "-" in the answer key, even though there is a ladder) ? |

Please check if your submission is different than what is intended. 2. Riad is still solving all the Puzzle 12 (ROMAN COOL-L-L) submissions. If you notice any grid is invalid, please post here. |
