About Prime Sudoku — Gameplay & Story
Welcome to the world of Prime Sudoku, where you'll find a classic set of number puzzles. Before starting the game, you can choose the appropriate difficulty level: from simple to expert. The size of the field remains unchanged — it is a 9x9 grid, divided into nine sectors. Difficulty only affects the number of initially open numbers: the higher the level, the fewer hints at the start. Your task is to fill all the cells so that the numbers from 1 to 9 are not repeated in rows, columns and small 3x3 squares. First, point to the desired cell, and then select a number in the panel on the right. If there is an error, the number will be highlighted in red. Train your logic and attentiveness by completing level after level in the intellectual game Prime Sudoku.
