Sudoku is a mathematical game based on logical reasoning, which requires players to solve puzzles through mathematical skills such as reasoning, analysis and reasoning. Therefore, students who are good at Sudoku usually have a certain mathematical foundation and logical thinking ability, but it does not mean that they are particularly good at mathematics.

Students who are good at Sudoku usually have the following characteristics:

1. Master basic mathematical concepts and skills: Sudoku requires some basic mathematical knowledge, such as the arrangement, combination and calculation of numbers, so students who are good at Sudoku usually have a good grasp of these concepts and skills.

2. Strong logical thinking ability: Sudoku requires players to solve problems through reasoning and analysis, so students with good Sudoku usually have strong logical thinking ability and can find solutions quickly.

3. Patience and care: Sudoku problems are usually complicated and require players to spend some time and energy to solve them. Therefore, students who are good at Sudoku usually have some patience and care, and can patiently analyze problems and solve them seriously.

But students who are good at Sudoku are not necessarily particularly good at math, because Sudoku mainly examines the player's logical reasoning ability, not the depth and breadth of mathematical knowledge. Therefore, students who are good at Sudoku may only be good at Sudoku, but not necessarily outstanding in other mathematics fields.
