## What is Sudoku?

Sudoku — Brain Puzzles brings the classic number game to your phone and tablet with a clean, modern look and gameplay that adapts to you.

THREE BOARD SIZES
• 4×4 (2×2 boxes, numbers 1–4) — perfect for first-timers and quick warm-ups
• 6×6 (2×3 boxes, numbers 1–6) — a comfortable next step
• 9×9 (3×3 boxes, numbers 1–9) — the original, timeless classic

THREE DIFFICULTIES
Easy, Medium and Hard for every board size. Clear Medium to unlock Hard, and rack up stars to chase that perfect 3-star run.

DAILY CHALLENGE
A fresh 9×9 medium puzzle every day, drawn deterministically from our puzzle pack — the same board for everyone, no internet required. Build a streak, climb the local records.
