How Did I Get Locked Out?
by FullDeck and Missing a Few Cards Open on SudokuPad
GAS
- Killer cages
- Lockout lines
The brief
- Normal sudoku rules apply. - Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage. - Lockout lines: Digits in the diamonds at the ends of a lockout line must differ by at least 4. Digits on a line must fall outside the range defined by their attached diamonds and may repeat if allowed by other rules.
