Straight answer: most apps promising "free offline word games, no ads" are lying about at least one of those three words, usually "no ads," and I found this out the hard way on a delayed train with a dead signal and forty minutes to kill. The apps below are the ones that held up when I switched to airplane mode and tried to play them, with the exact names, sizes, and the one trick worth doing before you download anything else.
The bit nobody tells you about "no ads" word games
Here's the uncomfortable truth: an app can call itself "no ads" in the app store listing and still be full of ads, because the claim usually refers to the base gameplay screen, not the hint button, the "extra life" popup, or the loading screen between levels. I've tested this. Wordscapes, one of the most downloaded word games on the planet, is marketed as free, and it is free to download, but it runs a full-screen video ad roughly every third level unless you pay for the ad-free version, which is £3.99 a month or a one-off £24.99 depending on which promo you land on that week.
Word Cookies does the same thing. So does Word Search Pro. The pattern is: the core puzzle screen is quiet, but the moment you tap "hint," "shuffle," or "next level," an ad loads if you have signal. Turn the signal off and the ad simply fails to load, so the game either freezes for a second, shows a grey box, or (best case) skips it entirely. That's the loophole that makes "offline" and "no ads" secretly the same request. If there's no connection, most ads physically cannot show up, which means the real question isn't "which word games have no ads" but "which word games work fine when the ad fails to load and don't punish you for it."
What I tested, and how
I did this over three weeks, not in an afternoon. I downloaded 19 apps across an Android phone (a Pixel) and an iPhone 14, put both into airplane mode, and played each one for at least ten minutes to see what broke. Seven held up cleanly. The rest either refused to open without a connection, locked half the puzzles behind a "sign in to continue" wall, or crashed when an ad slot tried and failed to load.
If you want the full breakdown across every genre, not just word games, my tested no-signal word games list has the longer version of this experiment with screenshots and exact download sizes. This post is the shorter, sharper version focused purely on the ad-free question, because that's the bit people message me about.
For Android (Google Play)
- Word Search Offline by Word Games Studio, 38MB, no sign-in, no data connection required at all after the initial download, and I did not see a single ad across four sessions in airplane mode. The trade-off: no daily bonus system, so it feels a bit plain.
- Wordly, Word Search Puzzle, around 45MB, has a small banner ad on the menu screen only, which vanishes entirely once you're offline because it can't fetch. Gameplay screen has never shown me an ad in six months of using it on flights.
- Anagram Twist (offline mode), you have to manually switch it to "offline mode" in settings before you leave wifi, or it will try to load an ad and hang for up to 15 seconds. Once switched, it's clean.
- Crossword Light by AppyNation, built specifically for low-connectivity use, roughly 4,000 puzzles pre-loaded, no ads at any point because they monetize through a separate paid "pro pack" rather than ad networks.
For iPhone (App Store)
- Word Search Unlimited, works fully offline, ads only appear on a results screen and only if there's a connection, so airplane mode strips them out completely.
- 7 Little Words: Offline Bundle, note the word "bundle" in the App Store, that's the paid tier (£1.99 one-off) that removes ads permanently rather than relying on no signal to hide them. Worth the two pounds if you fly often.
- Just Words by Etermax, free, offline, minimal ads that only trigger between matches when there's a live connection.
Notice something: three of these seven aren't ad-free by design, they're ad-free by circumstance, because they can't reach an ad server. That's a different thing to what most "best free word games" listicles claim, and it matters because the second you connect to wifi at the coffee shop, some of these apps will start showing ads again mid-game.
The train story, because it's the whole reason I tested any of this
I was on a delayed CrossCountry train from Birmingham to Edinburgh in September, the kind of delay where they announce "a further twenty minutes" three separate times and everyone in the carriage audibly sighs together. No signal for most of the route through the Peak District. I had four word game apps downloaded, three of which I'd installed the week before assuming they'd be fine offline because the app store said "no ads."
Two of them wouldn't even open. One showed a full black screen where an ad should have been and never recovered until I force-closed it. The fourth, which happened to be Word Search Offline, opened instantly and let me play six puzzles in a row with zero interruption. That's the app I've kept ever since, and it's the reason I now check every "offline" claim before I trust it, rather than after.
How to check before you download anything else
Do this five-step check and you'll save yourself the train-carriage frustration I went through:
- Read the last 20 reviews in the app store, sorted by "most recent," and search the page for the word "ads" using your phone's find-in-page tool. Recent complaints about ads override an old "no ads" listing.
- Check the download size. offline-first word games tend to be under 60MB because the entire puzzle set is bundled in. Anything over 150MB is usually pulling content live, which means it's built to expect a connection.
- Look at permissions before installing. If a "simple" word search game asks for location or contacts access, that's ad-network tracking infrastructure, and it's usually a sign the "no ads" claim is temporary or partial.
- Download it while still on wifi, then physically switch to airplane mode before opening it for the first time, and play for a full ten minutes. Don't judge it from the wifi test alone.
- Check whether the developer sells a separate "pro" or "ad-free" version in the same store listing. If they do, the free one is ad-supported by design, not by accident, and the ads will come back the moment you reconnect.
Word search, anagram, or crossword: they behave differently offline
This is the part most comparisons skip. Not all "word games" are built the same way under the hood, and that affects how well they survive no signal.
Word search apps are usually the safest offline bet because the puzzle grid is a static image or a locally generated array, nothing needs to load. Anagram and "word scramble" games are almost as safe, same logic. Crossword apps are the riskiest, because a lot of them (including some big licensed ones) pull the daily puzzle from a server each morning, so if you're offline before that daily sync happens, you get yesterday's puzzle or nothing at all. If crosswords are your thing specifically, download a pack-based one (Crossword Light works this way) rather than a "daily puzzle" one, and sync it the night before while you're still on wifi.
For a broader spread across genres, not just word puzzles, the zero data games roundup covers 1,116 tested options, which is useful if word games aren't the only thing you're stuck without on a long journey. And if you're testing specifically on Android and want the airplane mode results laid out app by app, the airplane mode tested Android games piece has 30 more that I ran through the same checklist.
What to do if the "ad-free" app still shows you an ad
It happens, usually because you had a flicker of signal you didn't notice, a plane's wifi handshake, a train station platform, a tunnel exit. Two things worth knowing:
- Force the phone into full airplane mode, not just "turn off mobile data," because some apps will still ping through wifi auto-connect even with data off.
- If ads persist even in full airplane mode, that app is caching ad content in advance when it detects you're about to lose signal, which some of the bigger free-to-play studios do now, it's a known workaround developers use to hit ad revenue targets. If you see it, it's a sign to delete and move to one of the smaller, less "gamified" apps I listed above, because the big studios with investor pressure behave differently to a small solo developer selling a £1.99 pack.
If you're the sort of person who wants word games for a specific occasion, long car journeys with kids for instance, it's worth knowing that the same "check before you fly or drive" logic applies to other genres too. I've done the same test for racing games without wifi for exactly that reason, since car journeys have the same "signal drops in and out" problem as trains do.
The honest sizing and battery cost worth knowing
One more concrete number: offline word games, the seven I've named above, use roughly 2 to 4 percent battery per hour of play on a modern phone, because there's no background network polling happening. Apps still trying (and failing) to reach an ad server in the background use closer to 8 to 10 percent per hour, because the phone keeps retrying the connection attempt every few seconds even while you're not aware of it. If your battery is draining fast on a "quiet" offline puzzle game, that's usually the tell that it's not as offline as it claims.

Frequently asked questions
Are there any truly free word games with no ads at all on Android?
Yes, but they're smaller, less polished apps like Word Search Offline and Crossword Light rather than the big-name ones, because major studios like Wordscapes and Word Cookies monetize through video ads by design, not by accident, and only remove them if you pay.
Why does my "offline" word game still show ads sometimes?
You probably still had a flicker of signal, or the app pre-cached an ad while you had wifi and shows it once you open the app, so full airplane mode before opening (not just turning off mobile data) is the reliable fix.
Do offline word games take up a lot of phone storage?
No, offline word games like Word Search Offline or Just Words are usually 35 to 45MB because the whole puzzle set ships in the download, compared to 150MB plus for apps that expect a live connection.
Is it worth paying £2 to £4 for the ad-free version of a game like Wordscapes?
If you play daily or fly often, yes, it usually pays for itself within a few weeks in saved frustration, but if you only play occasionally, one of the smaller free apps listed above will do the job without the upfront cost.
