a) Is the belt an open path or a loop?
b) What does "inside the belt mean?" Is it on the belt, in the enclosed space, or the union of the above? |

Inside a closed loop-"snake". Not on the snake. Edited by Riad Khanmagomedov 2013-04-05 9:18 PM

Does it mean that length and width both should be > 1, or the area should be > 1? |

Part of the puzzle is to figure out how it has to go.
The total of mines is given. It's the only place the 4th mine can go. |

Country : United States | Couple of questions on the optimizers.
For Domino Castle, the answer page notes that "some rows may not be used". Does that mean that if we build the castle into, say, a 12x12 grid, the empty rows/columns don't count against us as the minimum row/column value?
For Tetrasudoku, it's not explicitly stated, but I assume I know the answer: Must the sudoku be solvable at all? That is, is it acceptable to create a puzzle which has no solution, making the value of K=0? (I can't imagine that's okay, but figured I'd bring up the possibility anyway.) |

My reading of it is, you're drawing a single loop that passes through each dot. If you count the length of the line from dot to dot, then that length must go up or down by one from one segment to another as you travel the loop. In the example, if we start with the segment in the upper left of the grid and go clockwise, we start with a segment that's 2 units long. The next is 3 units long, then 2, 1, 2, 1, 2, 1, 2, 3, 2, 3, 2, 3, 4, 3, and back to the original 2 unit segment. |

Domino Castle : As you see from the example, only 4 rows are used. So it is not necessary to use all the rows.
Tetrasudoku : K > 0. Riad answered this earlier in this thread. |

Country : India | Just to confirm,
In Domino Castle we have to use all dominoes
i.e 1-1,1-2...1-7. ......7-7 so in all "49" dominoes right ?
or is it 1-1,1-2...1-7 then 2-2,2-3..2-7, 3-3.. so in that way 28 dominoes ??

Country : India | In domino Castle,
1) Is it possible to have a 2*2 domino (that is placing two dominoes adjacently) or 3*3 as there is no such restriction mentioned in rules ?
2) can castle walls touch each other at corners again nothing mentioned regarding this in rules ??

You have 28 dominoes. Using all dominoes build a castle. Castle is connected freeform figure. |

You can only place two dominoes adjacent (e.g. one above the other ) if both left ends match, and both right ends match. You have a set of 28 different dominoes to use, once each...
You have to follow the given rules, but if the rules don't restrict something, then you can do it. |
