The Best Ad-Free Sudoku App: What Actually Matters
Most Sudoku apps are free — until the ads start. Here's how to find one that respects your time.
You open a Sudoku app. You place a number. A full-screen ad covers the grid. You close it. You place another number. Another ad. Sound familiar?
Ad-supported Sudoku apps are everywhere, and most of them follow the same pattern: free to download, exhausting to use. If you're looking for an app that lets you actually play — without interruptions, paywalls, or dark patterns — here's what to look for.
What "Ad-Free" Should Actually Mean
Not all "ad-free" claims are equal. Some apps remove banner ads but keep interstitial ads between puzzles. Others hide ads behind a premium paywall — "ad-free" becomes "ad-free if you pay."
Here's what genuinely ad-free looks like:
- No banner ads — nothing competing for screen space while you solve
- No interstitial ads — no full-screen interruptions between puzzles or after mistakes
- No rewarded ads — no "watch an ad to get a hint" mechanics
- No paywall for ad removal — the app should be clean from the start, not clean after you subscribe
- No tracking ads — no third-party ad networks collecting your data
Features That Matter (Beyond "No Ads")
An ad-free experience is the baseline. Here's what separates a good Sudoku app from a great one:
| Feature | Why it matters | What to look for |
|---|---|---|
| Ad-free gameplay | Uninterrupted focus | No ads at all — not "fewer ads" or "ad-free tier" |
| Daily puzzles | Routine + freshness | A new puzzle every day, not a static library |
| Difficulty range | Growth over time | Easy through Expert/Master — room to improve |
| Handcrafted puzzles | Quality solving experience | Logic-solvable puzzles, not random generator output |
| Notes / pencil marks | Essential for harder levels | Built-in candidate notation |
| Printable puzzles | Offline / screen-free option | Free PDF downloads, multiple formats |
| Strategy guides | Learning path | Beginner through advanced techniques |
| Clean design | Reduces cognitive load | Minimal interface, readable grid, calm colours |
| No account required | Instant access | Play without signing up or giving an email |
