Quadcycle
(Published on 23. November 2023, 15:39 by SirSchmoopy)
Normal quadruple sudoku rules apply.
Cycles: Let a cycle be a set of cells in the same row of the grid created by repeatedly going to the column number indexed a cell's digit. E.g. for a cell in column 7 with a value of 1, the next cell in the cycle is the cell in column 1, the next cell is the cell in the column number matching the digit in column 1 and so on until reaching a column whose digit is 7 which would point back to the starting column.
In addition to normal quadruple sudoku rules, digits satisfying a clue must also be part of a cycle with length equal to the clue. It is only necessary for a single digit to match the cycle length of a given clue in case a digit for a clue happens to appear twice within the 4 adjacent cells
The below solved 6x6 shows valid clues given this restraint. Relevant cycles for clues are shaded for clarity.
Solution code: The digits in Row 2 + Column 9 from left to right and top to bottom (18 digits, no spaces)
