Sudoku Extreme: Classic Number 7.0

Sudoku Extreme offers a delightful experience with classic Sudoku puzzles suitable for both beginners and advanced players. It provides a wonderful opportunity to keep your mind engaged and unwind in your leisure time.

Each puzzle presents a unique challenge with only one solution. The grids are partially filled, leaving room for you to complete the remaining empty cells. Your task is to place the numbers 1-9 in such a way that each row, column, and 3x3 block contains each number only once.

• Highly customizable with a variety of beautiful themes and app settings to suit your preferences. Includes both light and dark AMOLED themes for optimal visual comfort.
