- Killer cages
- Kropki dots
- Thermometers
- Arrows
The brief
Normal Sudoku rules apply.
ARROWS- Numbers on arrows sum to the numbers in the arrow's circle or pill. The pill is read from left to right. Numbers do not repeat on arrows.
THERMOMETERS- Numbers on thermometers increase from the bulb end. There is an arrow and a thermo on all cube edges shown. SudokuPad does not show this very well.
KILLER CAGES- Numbers in cages sum to the number in the top left corner of the cage.
KROPKI PAIRS- Numbers with a white dot between them are consecutive. Not all possible dots are given.
