Sudoku+

Fill the grid so every row, column, and box holds 1–9 with no repeats.

How to play

1. Each of the nine rows, nine columns, and nine 3×3 boxes must contain the digits 1–9 exactly once.
2. Pick any difficulty — any difficulty counts for your streak.
3. Some days add a variant (Killer, Thermo, Sandwich, Miracle…) with an extra rule.

Controls

• Tap a cell, then a number. Use notes to pencil in candidates.

Example

5 3 .
6 . .
. 9 8

Tip · Hunt for cells with only one possible digit; pencil-mark the rest.
