Hva er Killer Sudoku?
Killer Sudoku er et logisk puslespill der hver rad, kolonne og 3×3-boks fortsatt bruker sifrene 1–9 én gang, mens prikkede bur må summere seg til summen av ledetråder.
KILLER SUDOKU-GUIDE
Killer Sudoku regler og strategier
Killer Sudoku beholder det klassiske 9×9 Sudoku-regelsettet, og legger deretter til bursummer som belønner ren logikk og nøye aritmetikk.
Kjerneregler
- Fill the 9×9 grid so each row, column, and 3×3 box contains 1–9 exactly once.
- Every cage must add up to the small number shown in its corner.
- Digits cannot repeat inside a cage, even when the cage crosses boxes or rows.
Nybegynnerstrategi
- Start with cages that have very small or very large sums because their digit combinations are limited.
- Use classic Sudoku scanning after each cage deduction to reveal singles in rows, columns, and boxes.
- Write candidate sums lightly, then remove combinations as nearby rows and boxes become constrained.

Killer Sudoku FAQ
What is the difference between Sudoku and Killer Sudoku?
Classic Sudoku uses row, column, and 3×3 box rules. Killer Sudoku keeps those rules and adds cage totals, so arithmetic becomes part of the logic.
Can digits repeat inside a Killer Sudoku cage?
No. A cage cannot contain repeated digits, even if the cells are in different rows, columns, or boxes.
Do I need to guess in Killer Sudoku?
A well-made Killer Sudoku puzzle can be solved with logic. Use cage combinations, classic Sudoku eliminations, and singles before guessing.
