Sudoku without sign-up
No account, no form, no email confirmation: at Sudoku Sagax you tap Play and you are in the puzzle. You can start right away and play without limit, with no registration. An account is optional and only unlocks extras, it is never a requirement to play.
Play instantly instead of registering first
Many Sudoku sites put a hurdle between you and the first puzzle: sign-up, newsletter, app install. Here that is gone. You open the page, pick a difficulty or a random puzzle, and play. No time limit, no artificial wall after three rounds, no nagging to sign up mid-game. Free play is unlimited.
What an account adds on top
Signing up only pays off once you want more than a single round. With an account you get:
- Fox ranks. Collect points and climb through the rank motifs.
- Daily streak. Keep a streak, with protection days and an optional reminder.
- Leaderboard. Compete in the weekly, monthly and daily standings.
- Progress across devices. Your best times and solved levels stay, whatever device you use.
All of that is an offer, not a condition. If you just want to solve puzzles in peace, you need none of it.
Your progress is not lost
If you play without an account, the browser remembers your progress locally. If you later decide to sign up after all, that guest progress can be claimed: solved puzzles, points and best times move into your account instead of starting over. So you lose nothing by committing later.

What does an account add if I can play without one?
An account saves your progress across devices and unlocks fox ranks, the daily streak with reminders, the leaderboard and achievements. You do not need it just to solve puzzles.

Your guest progress stays locally in your browser at first. If you sign up later, you can claim it, so solved puzzles and points carry over.
