Daily challenge FAQ
- What is the daily Sudoku challenge?
- It's one puzzle per calendar day, the same for every player. The difficulty rotates on a fixed schedule from the date—there's no randomness, so you always know you're playing the official grid.
- What time does the daily reset?
- We use a single global calendar day in UTC, matching the YYYY-MM-DD you see in the game header. If you're far from UTC, the date may look like the previous or next day compared to your local evening.
- Is the daily the same on mobile and desktop?
- Yes. The puzzle is generated from the date, so you can start on your phone and continue on a desktop with the same layout.
