The brief
- Normal sudoku rules apply. - The digit 1 (and ONLY the digit 1) is subject to antiknight, antiking, and nonconsecutive constraints. That is, cells that are a chess knight's move away from a 1 cannot contain the digit 1. Cells that are chess king's move away from a 1 cannot contain the digit 1. Cells that are orthogonally adjacent to a 1 cannot contain the digit 2. - Sandwiches: Clues outside the grid give the sum of the digits appearing between the 1 and the 9 in that row or column.
