Best Sudoku Apps That Don't Require a Subscription

The New York Times charges $69.99 per year for access to its Games bundle, and Sudoku.com's premium tier runs $9.99 per month. If you just want to play sudoku without handing over your credit card every month, you are not alone. Subscription fatigue is real, and puzzle apps are some of the worst offenders. The good news: several excellent sudoku apps require no subscription at all. Some are completely free. Others charge a single upfront price and never ask for money again. We tested every major option to find the best sudoku apps that respect your wallet.

Why So Many Sudoku Apps Push Subscriptions

The subscription model took over mobile gaming because it generates predictable recurring revenue. For publishers, a player paying $4.99 per month is worth far more over time than a one-time $4.99 purchase. That is great for their bottom line, but it means you are paying $60 or more per year for what is fundamentally a number puzzle with rules that have not changed since the 1980s.

Many subscription-based sudoku apps gate basic features behind the paywall: unlimited hints, daily challenges, statistics, themes, and even difficulty levels. The free tier exists primarily as a conversion funnel, not as a genuinely useful product. If you have ever hit a "Subscribe to unlock" wall in the middle of a puzzle, you know the frustration.

The Three Pricing Models for Sudoku Apps

Before comparing specific apps, it helps to understand the landscape:

• Completely free: No cost, no ads, no paywalled features. The full experience is available to everyone. This is rare but it exists.
• One-time purchase: You pay once (typically $3 to $7) and own the app forever. No recurring charges. Updates are usually included.
• Subscription: Monthly or annual payments ($3 to $10 per month, $30 to $70 per year). Missing a payment locks you out of premium features.

This guide focuses on the first two categories: apps where you either pay nothing or pay once.

Best Sudoku Apps With No Subscription

1. Sudoku Royale — Best Completely Free Option

Sudoku Royale is the standout here because it is genuinely, completely free. No subscription. No in-app purchases. No ads. No premium tier. Every feature is available the moment you download the app: Battle Royale mode (2-10 players with elimination rounds), 1v1 Duels, Practice mode with unlimited solo puzzles, ranked leaderboards, and the slide-to-select input that is the fastest on mobile.

What makes Sudoku Royale particularly interesting for subscription-weary players is that it offers features that other apps lock behind paywalls. Unlimited puzzles at every difficulty? Free. Statistics and progress tracking? Free. Multiple game modes? All free. The Glicko-2 ranking system gives competitive players something to work toward without charging for the privilege.

The only limitation is platform: Sudoku Royale is iOS only. If you are on Android, you will need to look at other options on this list.

2. Good Sudoku — Best One-Time Purchase

Good Sudoku by Zach Gage costs $3.99 once and you own it forever. No subscription, no recurring charges, no ads. For players who prefer the traditional "buy once, own forever" model, it is the gold standard. For a detailed breakdown, see our Sudoku Royale vs Good Sudoku comparison.

Good Sudoku's main draw is its AI hint system, which teaches you solving techniques rather than just giving you answers. The "Good" hints highlight which technique applies and explain why. The interface is polished and the puzzle generation is strong. If you want a premium solo sudoku experience and do not mind paying a few dollars upfront, this is the app to get.

The tradeoff: no multiplayer, no competitive features, and no ranked play. Good Sudoku is purely a solo experience. It is also iOS only (with an Apple Arcade version).

3. sudoku.coach — Best Free Web-Based Option

sudoku.coach is completely free, runs in any browser, and requires no account or installation. It is especially strong as a learning tool, with step-by-step technique explanations for everything from hidden singles to Swordfish patterns.

For players who want to improve their solving skills without paying a subscription for hints (looking at you, NYT), sudoku.coach is an excellent resource. The puzzle generator covers all difficulty levels, and the solver shows you exactly which technique to apply at each step.

The limitation: it is a web app, not a native mobile app. The experience is best on desktop. No multiplayer or competitive features.

4. Brainium Sudoku — Best Budget Option With Ad Removal

Brainium Sudoku is free to download and play with ads. A one-time purchase of around $2.99 removes all ads permanently — no subscription required. The interface is one of the cleanest in any sudoku app: minimal, elegant, and distraction-free. Available on both iOS and Android, making it the most accessible non-subscription option for Android users.

Puzzle quality is strong, difficulty levels are well-calibrated, and the app includes useful features like auto-pencil marks, error highlighting, and statistics. Daily challenges provide a reason to come back. It is a traditional solo sudoku app done well.

The Subscription Apps You Might Want to Avoid

Not every subscription is equally bad. But here is what you are paying for — and what you are missing without paying — in the two biggest subscription-based sudoku apps.

NYT Games ($69.99/year)

The New York Times bundles sudoku with its crossword, Wordle, Spelling Bee, and other games. If you play multiple NYT games daily, the bundle may make sense. But if you only want sudoku, you are paying almost $70 per year for a single puzzle game. The NYT sudoku itself is competent but unremarkable — no multiplayer, no ranking system, limited difficulty options. You are paying for the brand, not the features.

Sudoku.com Premium ($9.99/month)

Sudoku.com by Easybrain offers a generous free tier, but the premium subscription is aggressively marketed. Pop-ups, interstitial prompts, and locked features push you toward subscribing. At $9.99 per month ($119.88 per year if you pay monthly), it is one of the most expensive sudoku options available. The annual plan is $39.99, which is more reasonable but still recurring. See our Sudoku Royale vs Sudoku.com comparison for a full breakdown.

How Much Are You Actually Spending on Sudoku Subscriptions?

The numbers add up faster than most people realize:

• NYT Games: $69.99/year. Over 3 years, that is $210 for puzzles you could get elsewhere for free.
• Sudoku.com Premium (monthly): $9.99/month = $119.88 per year. Over 3 years: $359.64.
• Sudoku.com Premium (annual): $39.99/year. Over 3 years: $119.97.
• Good Sudoku: $3.99 once. Forever. No additional cost.
• Sudoku Royale: $0. Forever. No additional cost.

When you compare the long-term cost against what free and one-time purchase apps offer, the subscription model is hard to justify for sudoku specifically. These are not complex games that require server infrastructure and ongoing content creation on the scale of an MMO. Sudoku puzzles are generated algorithmically — the marginal cost of serving one more puzzle to one more player is essentially zero.

What You Actually Get From Free Apps

A common concern is that free apps must cut corners somewhere. Here is what the best non-subscription options actually deliver:

• Unlimited puzzles: Both Sudoku Royale and sudoku.coach offer unlimited puzzles at all difficulty levels.
• Multiple game modes: Sudoku Royale offers Battle Royale, Duel, and Practice modes — more variety than most paid apps.
• Competitive features: Sudoku Royale includes ranked matchmaking, a global leaderboard, and Glicko-2 rating — features that subscription apps typically do not offer at any price.
• Learning tools: sudoku.coach provides technique explanations that rival or exceed what NYT and Sudoku.com offer in their premium tiers.
• Clean interface: No ads means no interruptions. The experience is actually better than the "free tier" of subscription apps.

Our Recommendation

If you are on iPhone and want the most feature-rich free sudoku experience, start with Sudoku Royale. It covers solo play, competitive multiplayer, and ranked progression without ever asking for money. If you want a premium solo experience and do not mind a one-time purchase, add Good Sudoku for $3.99. For learning and technique practice, bookmark sudoku.coach.

For Android users, Brainium Sudoku with the one-time ad removal purchase is the best non-subscription option. sudoku.coach works on any device with a browser.

There is no reason to pay a monthly or annual subscription for sudoku in 2026. The best free sudoku apps have caught up to — and in many cases surpassed — what the subscription apps offer.
