How to play?

You are presented with a nine-by-nine grid divided into three-by-three squares. Some of the numbers are already in place, and you need to fill in the rest yourself. The rule is simple: each number from one to nine must appear exactly once in any row, any column, and any three-by-three square. Click on an empty cell and select a number. Did you place it correctly? You get five points. Did you make a mistake? The number will light up red, and the points will be deducted from your score. Start with the places where there are the fewest options. For example, if there are already eight numbers in a row, the ninth is easy to figure out. Gradually fill in the entire grid, relying on logic and the numbers you have already placed. The faster you finish without mistakes, the higher your final score will be.
