Goal

Fill the grid so every row, column, and 3×3 box contains the digits 1–9 once. No guessing required on well-formed puzzles — logic is enough.

Controls

Select a cell, then enter a digit with the number pad or keyboard.
Use pencil marks for candidates; clear or restart from the menu when you want a fresh grid.

Tips

Start with singles: any cell or unit with only one candidate left.
Keep pencil marks honest — erase candidates as soon as a digit is placed in the unit.
If you stall, pick a crowded box and re-check rows crossing it.
