No Dice
- Normal sudoku rules apply.
- Shade some cells in the grid such that all shaded cells are orthogonally connected AND all unshaded cells are orthogonally connected as well. There are exactly 21 unshaded cells.
- Digits in circles indicate how many of the 9 surrounding cells (including itself) are shaded. All circles are shaded.
- Clues on the outside of the grid are the sum of the shaded cells on the indicated diagonal.
- Digits along the long diagonals (marked with a blue line) may not repeat.
