## What is IRBIS SUDOKU?

Sudoku feels better with a clever cat beside you.

IRBIS SUDOKU turns classic number puzzles into a calm daily ritual. Choose a quick 4×4 or 6×6 board, settle into classic 9×9, and let Irbis guide you when you get stuck. No account is required, and your puzzles and progress stay available on your device.
