BYO Samurai
(Published yesterday, 22:30 by Chad)
This is a "build your own samurai" with modifiers
Rules:
- BYO Samurai: The five separate 9x9 grids must be placed within the larger connected grid, illustrated in the middle, in some order (to be deduced by the solver). For each 9x9 grid, normal sudoku rules apply.
MODIFIERS
- (C Grid) Copycat: Mark nine copycat cells in the grid such that every row, column, and 3x3 box contains exactly one copycat cell. Each copycat cell must contain a different digit. The value of a copycat cell is the digit in the cell rotationally opposite itself in the grid (180° rotation about the center of the grid). For example, if r1c3 is a copycat cell containing the digit 8 and r9c7 contains the digit 4, then r1c3 has a value of 4. Copycat cells may not get their value from a digit outside the copycat grid.
- (D Grid) Doublers: Mark nine doubler cells in the grid such that every row, column, and 3x3 box contains exactly one doubler cell. Each doubler cell must contain a different digit. The value of a doubler cell is exactly 2x the digit in that cell.
- (K Grid) Knapp Daneben: Mark nine cells in the grid such that every row, column, and 3x3 box contains exactly one marked cell. Each marked cell must contain a different digit. The value of a marked cell is either one more or one less than the digit in that cell.
- (N Grid) Negators: Mark nine negator cells in the grid such that every row, column, and 3x3 box contains exactly one negator cell. Each negator cell must contain a different digit. The value of a negator cell is the negative value of the digit in that cell. For example, if a negator cell contains the digit 5 then its value is -5.
- (V Grid) Vampire: Mark nine vampire cells in the grid such that every row, column, and 3x3 box contains exactly one vampire cell. Each vampire cell must contain a different digit. Vampire cells take exactly one sip of blood from an orthogonally adjacent cell. For clue purposes, vampire cells count exactly one more and the taken cell counts exactly one less. Two vampires may take from the same cell, in this case the cell taken counts exactly two less. Values may be less than 1 or greater than 9. Some vampires are not picky on which cell they take from.
- Other: Marked cells may not occupy the same cell as another marked cell in a different grid. The 3x3 box connecting two grids may contain multiple marked cells. If a vampire cell takes from the marked cell in a different grid, the vampire takes effect first, then the marked cell. For example, if a vampire cell takes from a doubler cell containing the digit 4, the value of that cell is 6.
CONSTRAINTS
- Killer Cages: Digits within a cage must not repeat. The values of each cell within a cage must sum to the total given in the top-left corner of the cage.
- Arrows: Values along an arrow must sum to the value in the arrow's circle.
- Double Arrows: The sum of the values along a double arrow line must equal the sum of the values in the circles at either end of the line.
- Quadruples: The digits in large white circles must appear as values in one of the four surrounding cells.
- Kropki Dots: Cells joined by a black dot must contain one value that's double the other. Cells joined by a white dot must contain consecutive values.
- Odd/Even Cells: Cells with a gray circle must contain an odd value. Cells with a gray square must contain an even value.
- Renban Lines: Values along a purple line must form a set of non-repeating consecutive values.
- German Whispers: Adjacent cells along a green line must contain values that differ by at least 5.
