The player has a 9x9 grid, divided into nine 3x3 sub-grids or regions. The goal is to fill in missing numbers from 1 to 9, making sure each row, column, and sub-grid contains each number only once.
Players start with a partially filled grid, with some numbers already provided. They must use their knowledge of logic and reasoning to figure out which numbers can go in each empty space. The game requires a deep understanding of patterns and relationships between numbers to solve.
