Long-form Project Note
A closer look at Calmsudoku
A free Sudoku website with difficulty levels, a daily puzzle, notes and optional live radio.
This note reflects a first-time user perspective.
A puzzle before an account
CalmSudoku puts its difficulty choices and Sudoku grid on the public site. Beginner through Expert levels sit alongside a daily challenge, and the page describes the game as free and ad-free. The daily board opened without a registration step during this first look.
A daily board on local time
The daily page explains that the local calendar date selects the puzzle. It also says completion is remembered on the current device. That gives the daily challenge a clear routine, while readers should not assume that progress follows them to another browser or device. No game was completed for this note, so persistence and the claims about unique solutions were not verified.
Radio stays optional
Notes, undo and erase controls are visible beside the puzzle. The radio selector lists several genres and a separate play control, keeping sound optional. The puzzle page and controls were inspected, but no stream was played. For someone who wants a browser Sudoku page with a daily prompt and optional background audio, the purpose is easy to understand.
