You can play Sudoku Royale without creating an account: it starts you as a guest, and signing in with Apple, email or Game Center is optional. OAKEVER's Sudoku: Brain Puzzle Games says on its listing that no login is required, and Gamovation's Sudoku: Daily Puzzles makes its Google or Facebook account optional. Most other sudoku apps do not mention accounts at all. The catch is that "no account" does not mean "no data": check the privacy label too.
People skip sign-up for different reasons. Some do not want another password. Some do not want to hand an email address to a game. Some are setting up a tablet for a parent or a child and want it to just work. This page covers what each app asks for, what signing in adds, and what is collected either way.

Sudoku Royale: guest first, account if you want one
Open Sudoku Royale and you are playing. There is no sign-up screen to get past, no email to confirm, and nothing to buy, so there is no purchase to restore either. Practice, the Daily Challenge, the 88-level Journey and the Dojo all work without signing in.
Signing in is there for one main reason: carrying your progress to another device. Progress syncs through your Sudoku Royale account, not iCloud, so if you play on an iPhone and an iPad, or replace your phone, sign in on both. You have three choices. Sign in with Apple can hide your real email address behind a relay address that Apple forwards, which is the most private of the three. Game Center uses the Apple Account already on your device, so there is no new password. Email works if you want an account that is not tied to Apple.
Be clear about what guest mode is not. The app still talks to its server: the Daily Challenge, the Dojo, belts and hints need a connection, and Sudoku Royale's privacy label lists data linked to you for app functionality, including identifiers (a user ID and a device ID), gameplay content and product interaction. Its label has no "Data Used to Track You" section, and the app contains no ad SDK. If you want an app that never goes online at all, read the offline sudoku apps page instead.
OAKEVER: no login, by its own description
Sudoku: Brain Puzzle Games is the one app here that leads with it: "100% privacy friendly and secure, no login required", along with full offline support. If the sign-up screen is what you are avoiding, it delivers. Its privacy label tells a more mixed story than its description, though: it lists a "Data Used to Track You" section, and its App Store age rating notes that it contains advertising. Our Sudoku Royale vs OAKEVER page compares the two in detail.
Gamovation, Sudoku Puzzle World and NYT Games
Gamovation's listing invites you to "secure your account with Google or Facebook for free". That is optional. If you take it up, the game is linked to your Google or Facebook account, which is a bigger step than a guest profile or Sign in with Apple.
Sudoku Puzzle World syncs progress through iCloud, per its listing. For many people that is the ideal arrangement: no separate account, and your progress follows your Apple Account to a new iPhone or iPad.
NYT Games is free to download, but its Games subscription is a New York Times product, so paid puzzles go with a New York Times account. If you only want sudoku and do not already subscribe, that is more account than the puzzle needs. See Sudoku Royale vs NYT Sudoku.
Game Center: the middle ground
Game Center is Apple's own gaming service. An app that supports it can give you leaderboards and achievements using the Apple Account you are already signed in with, without asking for an email or a password. If you want rankings but not another account, a Game Center app is a reasonable compromise. On this page, Game Center is listed for Sudoku Royale, Sudoku: Brain Puzzle Games, Sudoku Puzzle World, NYT Games.
Where another app is the better pick
- You want sync without any sign-in at all. Sudoku Puzzle World's iCloud sync does that; Sudoku Royale needs you to sign in before progress moves between devices.
- You want an app that never connects. OAKEVER's listing claims full offline support. Sudoku Royale's Practice and Journey play offline, but its daily, Dojo and hints do not.
- You play on Android. Sudoku Royale is iPhone and iPad only.
Our pick
For a sudoku app you can open and play with no sign-up, no ads and nothing to buy, get Sudoku Royale, and sign in later only if you want your progress on a second device. If what you really care about is what apps collect, the private sudoku apps page reads every privacy label, and the ad-free sudoku apps page covers ads. Every matchup is on the comparisons page.
Frequently Asked Questions
Is there a sudoku app that does not need an account?
Yes. Sudoku Royale starts you as a guest with no sign-up, and Sudoku: Brain Puzzle Games's listing says no login is required. Most sudoku apps do not ask for an account to play, but few say so on their listing.
Do I need to sign in to Sudoku Royale?
No. You start as a guest and can play Practice, the Daily Challenge, the Journey and the Dojo. Signing in with Apple, email or Game Center is optional and is how your progress moves to another device.
Will I lose my progress if I never sign in?
Sudoku Royale syncs progress through your account, not iCloud, so without signing in your progress is not carried to a new device. Sign in before you switch phones if you want to keep it.
Does playing as a guest mean no data is collected?
No. Guest mode means no sign-up, not no data. Sudoku Royale's privacy label lists identifiers, gameplay content and usage data linked to you for app functionality, with no tracking section. Of the apps on this page, the listings of Sudoku: Brain Puzzle Games, Sudoku: Daily Puzzles, Sudoku Puzzle World, NYT Games, Sudoku.com include a "Data Used to Track You" section.
What is the most private way to sign in to a game?
Sign in with Apple, if the app offers it, because it can hide your real email address behind a relay address. Game Center is another option that uses the Apple Account already on your device. Signing in with Google or Facebook links the game to that social account.
