Best Sudoku Apps for Android in 2026

The best sudoku apps for Android in 2026 are Sudoku.com, Andoku 3, and Brainium Sudoku. If you searched "best sudoku app Android," you are probably looking for a polished, reliable sudoku app you can download from the Play Store right now. We tested every major Android sudoku app and ranked them below. We also cover Sudoku Royale — the only battle royale sudoku game — which is currently iOS-only but coming to Android soon.

A Note About Sudoku Royale

Before diving into the Android rankings, we should address Sudoku Royale. If you follow the competitive sudoku space, you have probably heard about it: Sudoku Royale is the world's only battle royale sudoku game, where up to 10 players compete on the same puzzle with elimination rounds. It features slide-to-select input (the fastest on mobile), a Glicko-2 ranking system, and it is completely free with no ads.

The catch: it is iOS only right now. Android development is underway, and we will update this article as soon as it launches on the Play Store. If you have access to an iPhone or iPad, you can download it for free today. In the meantime, here are the best options actually available on Android.

Best Sudoku Apps for Android Compared

Note: Sudoku Royale is listed for comparison but is currently available on iOS only. Android launch is coming soon.

1. Sudoku.com — Best Overall Android Sudoku App

Sudoku.com by Easybrain is the most popular sudoku app on the Play Store, and for good reason. It offers the largest puzzle library of any mobile sudoku app, with thousands of puzzles across six difficulty levels from easy to expert. The interface is polished, the puzzle quality is consistent, and the app receives regular updates.

The free tier is generous — unlimited puzzles at all difficulty levels, daily challenges, and basic statistics. The tradeoff is ads. You will see interstitial ads between puzzles and banner ads during gameplay. They are not the most aggressive on the Play Store, but they are noticeable. The premium subscription ($4.99/month) removes all ads and unlocks additional themes, detailed statistics, and seasonal events.

For Android users who want a reliable, well-supported sudoku app with a massive puzzle library, Sudoku.com is the safe choice. It is the default recommendation for a reason — it does everything competently, even if nothing spectacularly. For a detailed feature comparison, see our Sudoku Royale vs Sudoku.com breakdown.

Best for: Players who want a large, reliable puzzle library with daily challenges and consistent quality.

The catch: Ads in the free tier; premium is a recurring subscription; no multiplayer; input speed is average.

2. Andoku 3 — Best Free Android Sudoku App

Andoku 3 is the hidden gem of Android sudoku. It is completely free with only minimal, non-intrusive ads, and it offers something most sudoku apps do not: a wide variety of sudoku variants. Beyond standard 9x9 puzzles, Andoku 3 includes Hyper Sudoku, X-Sudoku (diagonal), Percent Sudoku, and Color Sudoku. This makes it the most diverse sudoku experience available on Android.

The puzzle generator creates puzzles on the fly with a reliable difficulty grading system. The interface is functional rather than beautiful — it will not win any design awards, but it gets the job done without unnecessary clutter. Pencil marks, undo, and auto-save are all well-implemented.

For Android users who want variety, value, and a no-nonsense sudoku experience, Andoku 3 is hard to beat. The combination of free access, minimal ads, and variant support makes it uniquely appealing.

Best for: Players who want variety beyond standard sudoku, without paying anything.

The catch: Interface is dated compared to modern apps; no multiplayer; no technique teaching; limited statistics.

3. Brainium Sudoku — Best-Looking Android Sudoku App

Brainium Sudoku consistently ranks as one of the best-designed sudoku apps on any platform. The interface is clean, typography is excellent, and the overall experience feels premium even in the free tier. If aesthetics matter to you — and they should, since you will be staring at the grid for hours — Brainium is the best-looking option on Android.

The app includes all standard difficulty levels, auto-pencil marks, error highlighting, and detailed performance statistics that track your improvement over time. Daily challenges and a streak system add motivation to keep playing. The difficulty curve is well-calibrated, making it suitable for beginners through experts.

The free tier includes unlimited puzzles but serves banner and occasional interstitial ads. The one-time premium purchase ($2.99) removes all ads permanently — no subscriptions. This is a better deal than Sudoku.com's monthly subscription if you want an ad-free experience.

Best for: Players who value design and want a premium feel without a subscription.

The catch: Ads in free tier; no multiplayer; no variant support; no competitive features.

4. Enjoy Sudoku — Best for Learning on Android

Enjoy Sudoku is the closest thing Android has to Good Sudoku (which is iOS-only). It includes a built-in hint system that does not just tell you the answer — it explains which technique solves each cell and why. This makes it a genuine learning tool, not just a puzzle app.

The app teaches techniques from basic hidden singles through advanced strategies like X-Wings and naked pairs. For players who want to understand why a number goes in a specific cell — not just that it does — Enjoy Sudoku is the best option available on Android.

The $2.99 price tag buys you a completely ad-free experience with no subscriptions. The interface is clean and functional. Puzzle quality is excellent, with a reliable difficulty grading system.

Best for: Players who want to actively learn solving techniques while playing.

The catch: Not free (though $2.99 is reasonable); no multiplayer; smaller community than the big-name apps.

5. Sudoku - The Clean One — Best Minimalist Option

As the name suggests, this app focuses on doing one thing well: providing a clean, distraction-free sudoku experience. No gamification, no social features, no push notifications. Just sudoku. The interface strips away everything that is not essential to solving the puzzle.

The free tier includes unlimited puzzles with occasional ads. A one-time $3.99 purchase removes ads permanently. The app is lightweight, fast to load, and works well offline — making it a good choice for commutes or situations where you want to focus without distractions.

Best for: Players who want the simplest possible sudoku experience with zero distractions.

The catch: Very basic features; no statistics depth; no technique hints; no multiplayer.

What Android Is Missing: Competitive Multiplayer Sudoku

The biggest gap in the Android sudoku market is competitive multiplayer. Every app listed above is a solo experience. There is no Android app that lets you compete against other players on the same puzzle in real time.

This is exactly what Sudoku Royale's battle royale format offers on iOS: up to 10 players on the same board, elimination between rounds, and a global ranked leaderboard. The competitive multiplayer format transforms sudoku from a relaxation tool into a genuine competitive game — and it is the reason Sudoku Royale has generated the most excitement in the sudoku app space recently.

When Sudoku Royale launches on Android, it will fill this gap. Until then, Android users who want any form of competitive sudoku can try web-based options like sudoku.coach for time-trial challenges, though these are not real-time multiplayer.

Android vs iOS: The Sudoku App Gap

Android has strong options for traditional solo sudoku — Sudoku.com and Brainium are excellent. But iOS currently has a meaningful advantage in two areas:

• Competitive multiplayer: Sudoku Royale (iOS only) is the only real-time multiplayer sudoku app on any platform. There is no Android equivalent yet.
• Educational sudoku: Good Sudoku (iOS only) is the gold standard for technique-teaching sudoku apps. Enjoy Sudoku on Android is the closest alternative, but Good Sudoku's design and implementation are a level above.

For standard solo sudoku, the gap is negligible. Sudoku.com, Brainium, and Andoku 3 are all excellent on Android. The difference is in specialized categories — competitive play and educational depth — where iOS currently leads.

Tips for Choosing the Right Android Sudoku App

• If budget matters most: Andoku 3 is free with minimal ads and includes sudoku variants. Best value on Android.
• If design matters most: Brainium Sudoku has the cleanest, most polished interface. The $2.99 one-time purchase for ad removal is a good deal.
• If volume matters most: Sudoku.com has the largest puzzle library and the most active daily challenge community.
• If learning matters most: Enjoy Sudoku teaches techniques in a way that builds your skills over time.
• If competition matters most: Wait for Sudoku Royale on Android, or use an iPhone/iPad in the meantime. Nothing on Android currently offers real-time multiplayer sudoku.

The Verdict

Android has solid sudoku apps for solo players. Sudoku.com is the safe default, Andoku 3 is the best free option, and Brainium is the most polished. What Android is missing is competitive multiplayer — and that is exactly what Sudoku Royale will bring when it launches on the Play Store.

If you have access to an iOS device, try Sudoku Royale for free to see what competitive sudoku feels like. If you are Android-only, start with Andoku 3 (free, best variety) or Brainium (best design), and keep an eye out for Sudoku Royale's Android launch.
