Sudoku is a number-based puzzle game centered on logical reasoning.
Players fill in numbers from 1 to 9 on a 9×9 grid, ensuring that no number repeats within any row, column, or 3×3 box.

This game does not require any prior experience with Sudoku.
Even players who are completely new to Sudoku can gradually learn the basic rules through in-game guidance and story elements, and develop the ability to observe, reason, and determine the correct placements through hands-on play.

By solving each Sudoku puzzle step by step, players will naturally acquire the way of thinking behind Sudoku, and as the game progresses, they will encounter new challenges brought by different rules and variations.
