Do I drag numbers into the board?
No. The main interaction is tap a square, then tap a number.
Big Buttons
Sudoku with Big Buttons
Big-button Sudoku is about input comfort. Older adults should not have to drag tiny numbers or hunt for small controls around the board.
Input profile
- Visitor goal
- Use a Sudoku board that is comfortable with a mouse, finger, or tablet.
- Input model
- Select a square, then select a number from a large number pad.
- Safety feature
- Undo, erase, and given-square protection reduce stress after mistakes.
- Device fit
- Especially useful on tablets and touch laptops.
Controls should be obvious
The number pad uses large buttons because number entry is the main task. Secondary controls stay visible but should not dominate the board.
The same design supports keyboard users through arrow navigation and number keys.
