Calmsudoku.
CalmSudoku opens a browser puzzle without registration, with a daily challenge and optional radio alongside the grid.
Structured discovery note
The short version
CalmSudoku offers Beginner through Expert puzzles and a daily board tied to the local calendar date. The public game shows notes, undo and erase controls, plus a radio selector that waits for a play action. Its daily page says completion is remembered on the current device. The homepage and a rendered daily puzzle were inspected without completing a game or playing audio, so solution generation, saved progress and station availability remain untested.
