Battle Sudoku: Samurai Puzzle

Battle Sudoku is Samurai Sudoku reborn — five overlapping 9×9 grids on one board, plus the first real‑time 1v1 Sudoku duels. Solve solo, challenge a friend, climb the Hall of Champions.

⚔️ ONLINE BATTLE (1v1, real‑time)
Share the same puzzle with an opponent. Every correct number scores; a wrong move costs a life. Highest score on completion wins. Invite by code or challenge a friend, send playful stickers mid‑match, and watch the victory (or defeat) play out in a cinematic Zan finish.

🧩 SOLO SAMURAI SUDOKU
The classic five‑grid Samurai board (21×21) in four difficulties — Easy, Medium, Hard, Expert. Pinch to zoom, pan, undo, and pick up exactly where you left off with cloud save slots

🔢 CLASSIC 9×9 & 🎨 COLOUR SUDOKU
Prefer the traditional grid? Play Classic 9×9. Want something fresh? Colour Sudoku swaps digits for nine colours — solve entirely by colour, no numbers at all.

🔥 DAILY STREAKS & ACHIEVEMENTS
Build a daily streak, protect it with a Streak Freeze, and unlock warrior achievements as you go.

🏯 LEADERBOARDS & FRIENDS
