How to Play

1️⃣

One to Nine

Every row, column and 3×3 box holds each digit exactly once.

👆

Tap and Fill

Tap a square, then tap a number. Tap the same number again to clear it.

✏️

Pencil Notes

Turn on Notes to jot the candidates for a square before committing.

💡

Stuck?

A hint fills the selected square. Three per puzzle, so spend them well.

🎯

One Solution

Every puzzle is checked as it is built — no guessing between two answers.
