About the puzzle:
The usual killer rules apply. But there are also 9 additional windows (45-cages) from windoku:
1. r159c159
2. r159c234
3. r159c678
4. r234c159
5. r678c159
6. r234c234
7. r234c678
8. r678c234
9. r678c678
These "windows" are 45-cages, so repetition of numbers is not allowed!

Rating: SudokuSolver 3.0 rates it 4.5 with extended T&E. But please remember: the additional constraints are NOT included in this rating, so this rating is totally off!! IMO it's easy, maybe 1.0.
