Mini Sudoku #4

How to play Mini Sudoku

• Fill the grid so every row, column and box has the digits 1–6.
• No digit can repeat in a row, column or box.
• Tap a cell, then pick a number (or type it).
• Mistakes are highlighted in red as you go.
• Stuck? Use up to 3 hints (+10s each).

You get one attempt — the timer starts when you press Start and keeps running if you leave, even while this is open.
