About ChillSudoku
ChillSudoku is a small site built around one simple idea: Sudoku should feel relaxing. No signup wall. No popups blocking the grid. Open the page, pick a difficulty, start solving.
What's Here
One fresh puzzle every day at three difficulty levels (Easy, Medium, Hard). Pencil-mark notes, automatic timer, conflict highlighting. Your in-progress game saves locally so you can pick up where you left off.
How Puzzles Are Generated
Every puzzle is procedurally generated and verified to have exactly one solution. The daily seed is derived from the UTC date, so every player worldwide gets the same puzzle on the same day.
How We Stay Free
Display advertising, kept unobtrusive — no popovers, no autoplay video, no interstitials interrupting the solve. If an ad ever blocks the grid, email hello@chillsudoku.com and we'll fix it.
