This puzzle, or at least the break-in for it, literally came to me in a dream last night, during the part of my sleep cycle where I usually have nightmares instead. Therefore I have named this puzzle in celebration of its origin.

Note: you will need to complete this puzzle on SudokuPad to get the solution code, which will pop up in the message at the end.

RULES:

NORMAL SUDOKU RULES: fill the grid with digits 1-9 so that none repeat within a row, column or box.

RENBAN: Digits along pink renban lines must be a non-repeating set of consecutive digits, in any order. Note: there are two pairs of renban lines which cross each other creating an X. These lines are to be treated as separate from each other- lines of length 2 rather than length 4.

MINIMUM CELLS: Cells with arrows around them pointing to the inside of the cell must have a digit smaller than the rest of the digits adjacent to that cell.

XV: Cells with an X between them sum to 10. Not all Xs are necessarily given.

ANTI-KNIGHT: digits cannot repeat within a (chess) knight’s move.

ANTI-KING: digits cannot repeat within a (chess) king’s move.

Sweet dreams!
