Brick House
- Killer cages
- Kropki dots

The brief
Normal Sudoku rules apply. Numbers in cages sum to the number in the top left corner of the cage. Numbers cannot repeat in a cage. Numbers with an X between them sum to 10. Numbers with a black dot between them are in a ratio of 2:1. Numbers with a white dot between them are consecutive. Not all possible X and dots are given.
