Sudoku69 is fully playable without an account. Signing in with Google is free and optional, and it adds fresh puzzles you have not solved yet, points that follow you to every device, a game history you can resume anywhere and a record of your best scores.
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.
Points reward careful solving. Where they live depends on whether you are signed in:
| Guest | Signed in | |
|---|---|---|
| Where points are saved | On this device only | In your account, on every device |
| Lifetime limit | Up to 1,800 points, then you play without points | None |
| Daily soft cap | Not applicable | 1,800 points per day |
When you sign in for the first time, your guest points move into the account once, up to 1,800.
Signed-in players have a soft cap of 1,800 points per day. After it, points still count, but at 30 % (70 % less). Each puzzle you complete on the same day also gives 5 % fewer points, up to 35 % less. Everything resets at 00:00 UTC.
Points have no monetary value and cannot be bought, sold or exchanged. See the Terms of Use.
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.
The History and Completed pages are for signed-in players, so they are not open to search engines or guests.
We store only what these features need: your game history, completed games with time, points, mistakes and hints, and your points totals. You can delete all of it by deleting your account. The Privacy Policy lists everything in detail.
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.
