Sudoku

How to play

Start Sudoku by selecting a difficulty level. Your goal is to fill each row, column, and 3x3 grid with numbers from 1 to 9 without repeating any number. Tap a cell to select it, then choose a number to fill in. Use the erase button to clear mistakes. The game ends when all cells are correctly filled. The developer says the game saves your progress automatically, so you can close it and come back to the same grid later without starting over.

Controls explained

Tap a cell to select it, then choose a number to fill in. Use the erase button to clear a cell when you need to correct a mistake. The game begins once you pick a difficulty level, so choose one that matches how much time you want to spend on the grid. Everything runs with taps, which suits the feature phones the developer built the game for.

Tips

  • Before you place a number, check the row, column, and 3x3 box that the cell belongs to. A number is only valid if it does not already appear in any of those three places.
  • Start with the rows, columns, or boxes that already contain the most numbers. Fewer empty cells means fewer options to check.
  • Use the erase button as soon as you spot a mistake. Clearing a wrong number early keeps the rest of the grid easier to read.
  • If you are unsure about a cell, leave it empty and work on another part of the grid first. Coming back later can make the right number easier to see.
  • Pick a difficulty level that suits your experience. The game offers different levels, so you can start with one that feels comfortable and move to another when you are ready.
