Nikola: I think the answer is yes, and this is exactly what Riad meant when he wrote to me that "It is allowed to use arithmetic signs on both sides of the equal sign." What I am not sure about, though, is whether the answer key should include the final "=" (even though it is there when writing around the circle) - my current understanding based on the PB example is that the circular identity "32_PLUS_54=86_PLUS_0=..." is entered as "32_PLUS_54=86_PLUS_0" for the answer key.
In this case, write the answer as follows: 32_PLUS_54=86_PLUS_0 and 0_PLUS_68= 45_PLUS_23. |

Okay, but in his example he still got a result 1 (in one direction). Another example: 9x2=6x3= ... I don't want to put =18 because it would give 81 in the opposite direction. Maybe confirmation would be useful.
I gave an example with 1 to demonstrate three equal signs. This example is more successful: 7-6=5-4=3-2=7-6=5-4=3-2= etc. |

In puzzle 10, there is a digit missing in the "Answer key" sentence
"68=45_PLUS_23, 32_PLUS_54=8" should be ", 68=45_PLUS_23, 32_PLUS_54=86" ;-)
I'll correct it, thank you! |

Quote from the text: "Create a Minesweeper puzzle with a unique solution". Oh, that's so disappointing. It would have been more elegant to have to create a puzzle whose solution is unique when one takes into account the requirement that there should exist a loop (but which may have multiple solutions as a pure minesweeper puzzle ) -- so much so that I assumed that it was actually the task. Oh well, I shall redo it to make something that is also unique as a minesweeper puzzle. I was so happy with my submission, but it's definitely not unique at all as a minesweeper. |

Country : United Kingdom | In Puzzle 6, I'm a bit confused by the "vice versa" in the instructions for Turns. Is it saying that if the loop doesn't turn and enters a cell without a circle, then it must turn in the next cell (so you can't have more than one straight in a row)? |

Denis, I will check the uniqueness of the Minesweeper puzzle, and then watch a loop. |

In this part of the grid, the line behaves like in the puzzle "Every second turn". If there was a turn in a circle, then the next turn will be in a cell without a circle, then again in a circle, etc. |

"It is also possible for the line to make a turn and leave the grid, in this case it can turn in the next grid before meeting a circle."
Is there a vice versa too ? When the last turn before leaving the grid is a circle ?
Isn't it more accurate to say :
"It is also possible for the line to make a turn and leave the grid, in this case :
- if the last turn in the grid isn't a circle, it can turn in the next grid before meeting a circle.
- if the last turn in the grid is a circle, it can turn in the next grid at a circle"

Yes, this is what is intended to be conveyed. |

Well, that's not what the PB says. "Each name should intersect with at least one other" is not the same thing, and would be redundant if all words were connected.Another 12 hours of time wasted on solving one of these with the wrong set of instructions, and this time I don't think it was entirely my fault... (Sorry for being negative. But it is extremely frustrating. ) |

PB says make a crossword. One, not several crosswords. If the words are not related to each other, then you will get several crosswords. |

"Create a Minesweeper puzzle with a unique solution in the 9x9grid"
Do we agree that the instructions to solve a Minesweeper include a given number of mines to find ? As in Puzzle 6 for exemple
A grid could have multiple solutions without that number of mines, but when it is given as an instruction, the solution can become unique
The grid I submitted needs that number to have a unique solution
