MUNCH ANSWERS

Questions,
solved.

Everything you need to know before your first grid.

01Is Sudoku Monster free to play?

Yes. The core game is free to play. Optional purchases are available, but the logic is always on the house.

02Can I play offline?

Absolutely. Your puzzles live on your phone, so you can solve on the subway, on a plane, or anywhere without Wi-Fi.

03What makes Monster difficulty different?

Monster is the expert tier. It calls for advanced techniques such as X-Wing and Swordfish—not guesswork.

04Does it include notes, hints, and undo?

Yes. Tap the pencil to add candidates, use a hint when you need a nudge, and undo when a finger slips or you want to rethink a move.

05Do I need an account?

No account is required to play. Gameplay data stays on your device. Game Center can be used for leaderboards if you choose.

06How are ads and tracking handled?

The app asks before allowing personalized ad tracking. If you decline, ads remain contextual and the game works the same. Ad-free options are available.
