The Fourth Killer
- Killer cages
The brief
- Normal sudoku rules apply.
- Four yellow killer cages are hiding in the fog. Enter correct digits to clear the nearby fog. No guessing is necessary (or allowed!)
- Digits in a killer cage sum to the small number in the top left corner of that cage.
- Digits CAN repeat within a cage. In fact, a digit in a cage indicates exactly how many times that digit appears in that cage. Eg: a 5 in a cage means that there are five 5s in that cage.
- Grey lines are bulbless thermometers. Digits along a grey line must be arranged in ascending order, from one end to the other.
- White dots connect two consecutive digits. Not all possible white dots are shown.
