A software that allows you to input numbers into randomly generated groups.

Upon starting the game, you’ll be given a 9x9 grid which is evenly divided into squares. Your aim is to fill each blank with numbers 1 to 9, ensuring that no number is repeated in each row, column, and 3x3 square. The game also adds a new challenge, wherein the blanks will be separated into irregular groups by green lines. Numbers in each group should not be the same.
The game is easy to navigate. To fill in the blanks, simply click on a number on the number pad on the left side of the grid. If you want to erase a number, you can click the cross button at the bottom of the number pad. But if you’re stuck, don’t worry! Click the Hint button under the grid to reveal one of the answers. However, note that each time you receive a hint, 100 seconds will be added to the amount of time you have spent, which is shown at the bottom-left corner of the screen.
Lastly, challenge yourself by filling in the blocks with speed and style. Climb to the top of the leaderboard and brag to your friends about your puzzle-solving skills!
