Logic enthusiasts seeking a mental workout will find endless satisfaction in Multi Sudoku. This challenging brain teaser expands the classic grid concept by interconnecting multiple puzzle structures into one cohesive brain training session. You need to fill in missing digits across various overlapping boards while adhering to the rule that every row, column, and 3x3 square must contain unique numbers.

With 2,500 levels ranging from simple to incredibly complex puzzles, you will never run out of grid configurations to master. The game includes unique variations like Samurai Sudoku and Butterfly patterns that force you to think outside the traditional box. Advanced settings allow you to toggle candidate markers and customize your interface for a personalized experience.

Each individual 9x9 Sudoku grid must satisfy the condition of uniqueness for digits - in columns, rows, and each of the 3x3 squares, every digit should appear only once. Some numbers are already pre-set. You need to fill in the missing digits using logic.
