Slow Stairs
- Killer cages
- Kropki dots
- Slow thermometers
The brief
Normal sudoku rules apply. Digits on a slow thermometer must never decrease from the bulb end. Digits in a dotted cage must sum to the total given in the top left corner of the cage without repetition. Cells separated by a black dot has one digit double the other. Cells separated by a white dot are consecutive. Not all dots are given.
