Twin Paradox (Holes, Gemini)
(Eingestellt am 15. Februar 2026, 16:51 Uhr von gdc)
This puzzle combines the gemini ("twin grid") rule by Christounet with the black holes ruleset by heliopolix. Unlike other gemini puzzles, both grids have the same rules (and the same clues) but maybe there is a reason they have to have different solutions. Paradox, isn't it?
Normal 4x4 sudoku rules apply in both grids.
Black Holes (Nullifiers): For each grid, place four black holes, one in each row, column, and box. Digits may not repeat on black holes. For the purposes of the clues, black holes have a value of zero.
White Holes (Doublers): For each grid, place four white holes, one in each row, column, and box. Digits may not repeat on white holes. For the purposes of the clues, white holes double the value of a cell.
White holes and black holes never share the same cell.
Killer Cages: Digits in cages cannot repeat (though values can). Values within a cage sum to the clue in the top left. A killer cage must contain an equal number of black and white holes, but that number may be zero.
Teleporting Little Killers: Clues outside the grid with arrows give the sum of digits along a diagonally-traveling path starting in the cell pointed at by the arrow. This path only ends when it reaches an edge of a grid. When the path enters a black hole cell it teleports to the white hole cell with the same digit in the other grid maintaining the direction of travel of the original path and including the value of both holes in its sum. The path must visit the same number of black and white holes, but that number may be zero.
Hole Sandwiches: Clues outside the grid without arrows give the sum of the digits between the holes in the row or column, not including the holes.
Black Holes (Nullifiers): For each grid, place four black holes, one in each row, column, and box. Digits may not repeat on black holes. For the purposes of the clues, black holes have a value of zero.
White Holes (Doublers): For each grid, place four white holes, one in each row, column, and box. Digits may not repeat on white holes. For the purposes of the clues, white holes double the value of a cell.

Rules
Lösungscode: Digits in row 1 (ignoring doublers/nullifiers) of both grids from left to right (4 digits each, 8 digits total). Starting with the grid that has a smaller digit in the top-left corner.
