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.
