Frequently asked questions

What does Killer Sudoku Generator do?

Generate a Killer Sudoku with sum cages and a verified unique solution — no operations, just add each cage.

When would I actually use this?

Making something to print: a puzzle for a classroom, a grid for a rainy afternoon, or a set of rounds for a quiz night.

What is the most common mistake?

Printing before checking the solution. A grid is generated fresh each time, so the answer key belongs to that exact grid and to no other — reloading the page gives a different puzzle.

How is Killer Sudoku Generator different from Sudoku Generator & Solver?

They sit next to each other but answer different questions: Sudoku Generator & Solver is the one to open when you need it to generate a unique 9×9 Sudoku at four difficulties, or paste any puzzle and solve it instantly. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

24 Game Solver is the closest one after this: Enter four numbers and find every way to reach 24 using +, −, × and ÷ with each number exactly once.

What else is worth having open alongside it?

Baby Eye Color Predictor and Baby Name Generator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Puzzles are generated and, where it applies, verified to have exactly one solution before being shown. Word lists are written per language, so no grid depends on translating an English one.
