How to play Ultimate Sudoku game

  • Objective: The goal is to fill the 9×9 grid with numbers from 1 to 9. Make sure that each row, each column, and each of the nine 3×3 subgrids (also known as boxes or regions) contains all the numbers from 1 to 9 without repetition.
  • Starting Grid: The game begins with some numbers already filled in the grid. These are called “clues” or “givens”, and they help you get started.
  • Number Placement: You can select a cell and choose a number from 1 to 9 to place in that cell. The selected number will only be valid if it doesn’t violate the rules of Sudoku (no repetition in the same row, column, or 3×3 subgrid).
  • Three Game Modes:
    • Cell First: Click on the empty cell you want to fill and then select a number to place in it.
      Number First: Click on the number you want to place, and then click on the empty cell where you want to put it.
    • Note Mode: If you’re unsure about a number, you can use the “Note Mode” to write down possible options in an empty cell. This helps you keep track of potential numbers without committing to a final choice.
    • Strategy: To solve the puzzle, use your logical thinking skills and deduction. Look for numbers that can be placed easily based on the existing clues and the rules of Sudoku. Gradually fill in more numbers, which will unlock new possibilities for other cells.
  • Checking for Errors: It automatically highlights incorrect placements, so you can correct them before proceeding.
  • Trial and Error: Sometimes, you might need to try different numbers in a cell to see what works. Don’t worry; Sudoku is all about experimenting and finding the right combination of numbers.
  • Completion: Continue filling the grid until you’ve successfully placed all the numbers, adhering to the rules of Sudoku.
