In the Killer Su Doku category you will find more kinds of these puzzles, including Killer Samurai Sudoku, Killer TriDoku, Killer TwoDoku and other variants.
Make sure to also check the Main page of this site, because that’s where occasionally other puzzles are posted: Kakuro (Cross Sums), Jigsaw Sudoku, Outside Sudoku, CalcuDoku, Picross (aka Hanjie, Griddlers, Nonograms).
Instructions and rules:
1. All standard Sudoku rules apply.
2. Numbers in “cages” (dotted lines) must add up to the cage sum indicated for that cage.
3. Numbers CANNOT be repeated within a cage, even if it is possible by other Sudoku rules.
4. If you see an “X” across the puzzle (diagonals) it means that numbers CANNOT be repeated on those diagonals.
5. Difficulty levels in increasing order: EASY – COOL – THINKER – BRAIN – IQ – INSANE
Killer Sudoku solving techniques are explained here:
Rule of 45: Innies and Outies

The daily puzzle did not update yet for January 2?

Still no update….Two days without puzzles….Going through withdrawal! Everything ok in the home office?

I’m missing the new puzzles, too. Maybe the “home office” is taking a well-deserved holiday? I hope they’ll be back soon.

Patricia, you were right, I did take a short holiday and forgot to update the daily Killer Suduko puzzles. Now I am back and the puzzles are back.
