How to Play Medium Sudoku

Sudoku is a number puzzle where every row, every column, and every 3×3 box must contain the numbers 1 through 9 without repeating. Medium Sudoku gives you fewer starting numbers than an easy puzzle, so it asks you to think a little more carefully.

Pick a Square

Tap any empty square on the board. The selected square will highlight so you know where your number will go.

Choose a Number

Use the number buttons below the board or type a number on your keyboard if you are using a computer.

Check Your Progress

Press Check to review the puzzle. Correct entries turn green and incorrect entries are gently marked.

Why This Sudoku Game Is Senior-Friendly

This Medium Sudoku game was built with large number buttons, a no-timer format, clear spacing, and helpful hints. The board resizes for mobile screens, while still keeping the puzzle centered and readable.

Because Sudoku uses a 9×9 grid, some phones may feel a little tight. That is normal. The game remains playable on mobile, but many players will find it more comfortable on a tablet, laptop, or desktop computer.

Note: This game is for enjoyment, light mental activity, and entertainment. It is not a medical or cognitive assessment. If you are concerned about memory changes, confusion, or cognitive health, speak with a qualified healthcare professional.
