Daily Sudoku for people who like to think.
One free daily board. No casino noise. Pro is for players who want the deeper game.
The free game is a real daily habit. Pro is where the deeper trainer, replay, sync, and polish live.
Nineward hints are written to teach, not just spoil. Free players get one teaching hint per puzzle; Pro is for people who want to keep training after that first nudge.
Row 5 only has one place left for a 5: every other cell in that row is either filled or can’t accept 5.
Calm lets wrong entries become slips, not a game over. Challenge keeps the classic three-mistake limit and is the mode that counts for streak-eligible daily runs.
Pro keeps a replay library so you can scrub through solves, study mistakes, and spot the turn where a hard board finally opened up.
Free play includes the simple pencil flow you expect. Pro unlocks the fuller note set, including dot notes and board-tuning controls for players who live in candidates.
Everyone gets the warm Atelier board. Pro unlocks the full set of calm palettes and the extra board customization that keeps long sessions easy on the eyes.
Free gets you the daily and a little extra practice. Pro is the $8.99/year plan for harder boards, unlimited generated puzzles, replay, sync, premium music, themes, and the serious-solver tools once purchases go live.
The daily habit, no credit card ceremony.
For players who want the whole training room.
Built for a phone in your hand, not a web page pretending to fit there.
Easy and Medium free; Hard and Expert in Pro.
Big grid, calm cell highlights, one-row toolbar.
Final time, technique callouts, share.
