Features: Sudoku is not math but a game that trains logical thinking. The original creator of "Sudoku" was the 18th-century Swiss mathematician Euler. The rules of the game are simple: in a 9x9 grid, each row and each column must contain the numbers 1 to 9, and each small 3x3 grid must also contain the numbers 1 to 9, but each number can only appear once in each row, column, and small grid. Now, you can see people playing Sudoku with paper and pencil, on computers, online, and even on their phones. In the UK, some teachers advocate using it to train students' brains. What about you? If you don't want your brain to rust, hurry up and try Sudoku! This book contains 300 puzzles in the "Two-Stage Green Belt" to challenge your mental limits! The book is richly illustrated, combining scientific rigor, knowledge, and fun. Through various games and layers of reasoning, it develops your intellectual potential with ingenious stories, engaging plots, and exquisite visuals.
