Why Sign In to Sudoku69
Signing in to Sudoku69 with Google or Facebook is free and takes one click. It adds fresh puzzles you have not solved yet, coins that follow you to every device, a game history you can resume anywhere and a record of your best scores. Signed-in players will also not see ads, as explained in Sudoku69: play with no ads.
Do I get new puzzles when I sign in?
Yes. Signed-in players only get puzzles they have not solved, and never one that is already in their History. Guests get a random puzzle each time, so the same puzzle can come back.
What happens to my coins?
Coins reward careful solving. Where they live depends on whether you are signed in:
| Guest | Signed in | |
|---|---|---|
| Where coins are saved | On this device only | In your account, on every device |
| Lifetime limit | Up to 1,800 coins, then you play without coins | None |
| Daily soft cap | Not applicable | 1,800 coins per day |
When you sign in for the first time, your guest coins move into the account once, up to 1,800.
How does the daily cap work?
Signed-in players have a soft cap of 1,800 coins per day. After it, coins still count, but at 30 % (70 % less). Each puzzle you complete on the same day also gives 5 % fewer coins, up to 35 % less. Everything resets at 00:00 UTC.
Coins have no monetary value and cannot be bought, sold or exchanged. See the Terms of Use.
Can I carry on a game on another device?
Your History keeps the last 10 games you started. Open one on any device and carry on where you stopped. A completed game leaves History and moves to your completed puzzles.
What else does an account keep?
- Completed puzzles: a page with filters by game mode and difficulty, so you can look back at what you have solved.
- Best scores: your top results for each mode and difficulty, for today, this week, this month and all time.
The History and Completed pages are for signed-in players, so they are not open to search engines or guests.
Is my data safe?
We store only what these features need: your game history, completed games with time, coins, mistakes and hints, and your coins totals. You can delete all of it by deleting your account. The Privacy Policy lists everything in detail.
Where do I start?
Pick a level that suits you. If you are unsure, read the difficulty levels guide, or jump straight into an easy classic puzzle and sign in whenever you like.
