About game
Sudoku: Mind Challenge is a modern take on the legendary puzzle with a sleek design and a smart AI opponent. Choose a difficulty from easy to brutal, tackle daily challenges and compare scores with other players. The built-in hint system explains the logic of each move rather than just giving the answer - you actually get better at the game. Progress saving, win stats and win streaks will keep you coming back every day.
How to play
Fill the 9×9 grid so that every row, column and 3×3 box contains the digits 1–9 exactly once. Tap an empty cell, then select a number from the panel at the bottom. Use the pencil (✏️) for notes and the lightbulb (💡) for hints. Avoid mistakes — each one costs you points!
