Sudoku is one of those games that never goes out of style. You don’t need fancy graphics, fast fingers, or a gaming headset to enjoy it. All you need is a little focus, a love for logic, and maybe a bit of patience. It’s a game that challenges your brain without overwhelming it, and now, you can enjoy it anywhere, anytime, at onlineVgames.


What Exactly is Sudoku?

Sudoku is a number puzzle. The most common version is played on a 9×9 grid, which is divided into nine smaller 3×3 boxes. Some of the squares already have numbers in them. Your job is to fill in the rest of the squares so that:

  • Every row contains the numbers 1 to 9
  • Every column contains the numbers 1 to 9
  • Every 3×3 box contains the numbers 1 to 9

And the trick? You can’t repeat any numbers within the same row, column, or box. It sounds simple at first, but as you keep playing, you’ll realize how clever and deep the game really is.
