In 11 can the ball cross its own path?
No.
So this translates to - each half white and fully white cell needs to be visited exactly once?

I think the missing thing is that the solution to 12 must be unique. It should be added to the PB.
The loop must be unique! |

More questions:
3: For the purposes of lawns, each diagonal segment is of the same length as horizontal/vertical segments? Also, can you go diagonally through a white cell, without any lawn next to you?
4: Can names repeat in the grid?
8: For the cells without slashes, the clues point to the longer direction (the direction with more than 1 cell)? Is it possible to make it more similar to Kakuro, so each square is slashed?
3. Yes.
4. No.
8. Yes, to the longer direction. |

The white cell can be crossed twice. The path should not overlap with itself. |

Location: Germany | For the solution code to puzzle 3, would a diagonal of length 2 be counted as 2 (it's two unit diagonals) or as 0 (it's not a unit diagonal)? |

Location: Turkey | 11. Rollball variation.
- The ball goes through the centres of all white half cells and all fully white cells. So does it go through all current white cells, or can some of white cells be completely blackened by adding triangles?
- "The ball can roll out of the grid or stay inside the grid" Does this sentence refer to the end of the route?

The diagonal of length 2 is counted as 2. |

1. First you need to blacken some cells. Then through all the remaining white cells and half cells draw the route.
2. Yes, the end of the route. |

I don’t get it, can the road cross itself or not? Because your first answer is “No”, and the second one is “Yes”. Did you mean that a horizontal road segment and a vertical road segment can cross on a fully white cell? Are we talking about the 2017 April’s Opti-Roll puzzle; the road act same in here about crossing? |

For 10. Does minimum mean the amount of digits or the sum of their values?
For 11. Can you place a black triangle in a given cell with a triangle to turn it into a fully black cell?
10. Minimize the sum by using fewer digits.
11. Yes.
Questions for 11:
Could one also place two triangles in an entirely white cell, turning it entirely black?
And if so, would you name the two trinagles as A and D or as B and ?
Also, in what order are the tringales to be given in the solution code? If it's in order of the path (as the example seems to imply) then where/how would one put in the triangles creating a full black cell, as the path doesn't visit them ?

I understand the question as it is translated the translator. If the issue was not the word "own", I understood it clearly. The path can intersect itself (the fully white cell can be crossed twice), but the path should not overlap with itself. |

It's possible. The order in the solution code is arbitrary. |

It's possible N=0?
Then a route with lenght=2 and N=0, i.e., is better that other with lenght= 40 and N=1?

A route must pass through all the white cells and half cells. If N=0, then the length of route cannot be 2 (this is much less than the number of white cells and white half-cells in the picture). |

Fixed the end time. It should show correct time now. |
