What is inside
Inside Nineward Sudoku.
Daily, Killer, and Arcade Sprint puzzles
Pick your pace: classic daily focus, deeper Killer logic, or a faster sprint when your brain wants a quick win.
Hints that teach, not spoil
Stuck does not have to mean "show me the answer." Nineward explains the logic so you get better, not just unstuck.
Archive, streaks, and (with Pro) replays and cloud sync
Keep your history, protect your streak, and come back to the board without starting over from scratch.
Why it exists
Built for a reason.
Most Sudoku apps take a great puzzle and bury it under noise. Nineward strips it back to what you came for: the solve.
Made for people who want a calm daily Sudoku habit that feels premium, focused, and just challenging enough to make tomorrow's puzzle tempting.
