Sudoku for Seniors is a classic number puzzle rebuilt for comfortable reading and steady daily practice. Fill the 9ร—9 grid so every row, column, and 3ร—3 box contains the digits 1โ€“9 โ€” with large numbers, clear contrast, and tools that help you think without rushing.

Large numbers & eye-friendly layout

Digits and cells are sized for aging vision. High-contrast grids and an uncluttered board reduce eye strain on both phones and tablets, so you can focus on logic instead of squinting at tiny marks.

Five difficulty levels

Start gently and grow at your own pace. Choose from easier boards for a relaxing warm-up to harder grids that demand deeper deduction โ€” always the same classic Sudoku rules, never a timed race unless you want the challenge.

Smart hints & pencil mode

Stuck on a tough cell? Smart hints point you toward useful next steps. Pencil mode lets you jot candidate numbers lightly, then commit when you are sure โ€” just like working a paper puzzle with room to think.

Daily challenges for a steady habit

Fresh daily boards give you a reason to open the app each day. Short sessions keep your mind sharp; longer ones let you settle into the quiet satisfaction of a clean solve.

How to play

  1. Select an empty cell and enter a number from 1 to 9.
  2. Avoid repeating any digit in the same row, column, or 3ร—3 box.
  3. Use pencil notes to track possibilities.
  4. Clear the board completely to finish the puzzle.
