Best Offline Word Games for iPhone and Android in 2026: What Still Works With No Wifi

The week of Thanksgiving is one of the busiest travel weeks of the year in the US, which means a lot of people are about to discover which of their games still open in airplane mode. Word games are a good thing to have on a flight, in a car with no bars, or at a relative's house with a wifi password nobody remembers. The trouble is that "offline" on a store listing means different things to different apps, and the only way to know is to know how the game is built.

One note before the list: we make one of the games below (KEYCAPS). We will say where it fits, where something else fits better, and what each one does not do.

Why some word games stop working without a connection

A word game needs the internet for one of five things. If it needs any of them to start a round, it will not work on a plane.

A shared daily puzzle. Wordle, Connections, Strands and most "daily" games fetch today's puzzle from a server so everyone gets the same one. No connection, no puzzle.

A live opponent. Words With Friends 2 and other online multiplayer games sync every move through a server. Without one, the game has nobody to send your word to.

Content it downloads later. Some games ship a small app and download word lists or level packs the first time you open a mode. That first download fails silently in airplane mode, and the game looks frozen.

Ads. An ad-supported game may pause where an ad would load. Most carry on after a moment; a few hang.

A sign-in. A game that checks your account at launch may refuse to open without one.

Games that ship their puzzles inside the app and need no account (level-based games, most word search apps, and games that generate boards on the device) are the ones that keep going.

How to check a word game really works offline: the two-minute airplane-mode test

Run this the night before a trip, with wifi still on hand, for every game you plan to play:

1. Update and open the game on wifi. Let it finish any download it wants, and dismiss any first-launch screens.

2. Open every mode you plan to play. Start one round in each, so any word list or level pack it fetches on first use is already on the phone.

3. Force-close the app. Swipe it away from the app switcher, so you are testing a cold start, the way it will launch on the plane.

4. Turn on airplane mode and make sure wifi is off too. Airplane mode on most phones leaves wifi on if you turned it back on last time.

5. Reopen the game and play a full round of each mode. Whatever works now is what you will have in the air. Whatever spins, delete from your travel folder.

If you are traveling with other people and want to play together, test that too: most multiplayer modes die the moment the connection does. The exception is a game that connects phones directly to each other.

The best offline word games, by use case

Best for a word game with no signal, alone or with a group: KEYCAPS™

KEYCAPS is the word game we make. Each keypair fixes a start letter and an end letter, and any real word that fits between them counts, so there is no hidden answer to guess and no single word to get stuck on. Alone, there is an Adventure campaign of worlds with a CPU boss at the end of each, three fixed tours with no clock (the Alphabet, which covers all twenty-six letters exactly once, plus Seams and High Pair), and Endless, where every letter you find buys time back. Every solo mode works offline.

What makes it unusual on this list is the group case. One phone hosts a live race over Bluetooth and everyone nearby joins, up to eight people, with no wifi and no cell signal. That is a row of seats on a plane, a back seat on a long drive, or a cabin with no bars, all playing the same board at once. Nobody needs an account. Because any fitting word counts, two people can clear the same board without a single word in common, so a nine-year-old and a grandparent can play the same round.

What it costs: free is the whole game, every mode and every board, and ads never appear on a gameboard. Fan-supported is $4.99 once and removes the ads; KEYCAPS+ is $3.99 a month or $29.99 a year for tools such as unlimited hints. It is on the App Store and Google Play. Today's Daily is also at keyca.ps in any browser, but a website needs a connection to load, so on a plane use the app. More on the KEYCAPS page. Not ideal if: you want a crossword-style grid to fill in or hundreds of levels with a story; Wordscapes fits that better.

Best for long, relaxing solo sessions: Wordscapes

Wordscapes is the long-running level-based word game on iPhone and Android: a wheel of letters, a small crossword to fill by swiping words from it, and thousands of levels against calm landscape backgrounds. Because its regular levels are a progression rather than a daily drop, players widely report that it keeps working offline once the app has been installed and opened on a connection, and many note that the ads largely disappear when the connection does. Events, tournaments, some daily content and syncing your progress need a connection. It is free with ads and in-app purchases. Not ideal if: you want to play with anyone else, or you dislike ads when you are back online.

Best for a calm, no-pressure flight: an offline word search app

Word search is the easiest kind of word game to make work offline, because the puzzles are small and generated or shipped with the app. There are dozens of free ones on both stores, and their quality and ad load vary more than their names do. Search your store for "word search offline," pick one whose listing says it works without internet and does not require a sign-in, and run the airplane-mode test before you leave. Not ideal if: you want a challenge; word search is a game for winding down.

Best with no phone at all: Boggle and Bananagrams

The most reliable offline word games have no battery. Boggle (letter cubes in a tray, three minutes on the timer, write down every word you can find in the grid) and Bananagrams (letter tiles in a zip pouch, everyone builds their own crossword at once, first to use every tile wins) both pack small, need no signal, and work for a table of mixed ages. Bananagrams in particular travels well in a carry-on. Not ideal if: you are in a seat with a tray table the size of a paperback.

Not for a flight: daily puzzles and online multiplayer

Wordle, Connections, Strands, Spelling Bee and other daily puzzles need a connection to fetch the day's puzzle, and Words With Friends 2 needs one to send a move. If a daily puzzle is part of your routine, open it at the gate while you still have signal: once it has loaded it will usually stay playable, but you cannot count on it, and you cannot get tomorrow's early.

A word game with no app at all: the two-letter race

If the phones are dead, here is a game for any number of people that needs a pen and a scrap of paper. Someone picks two letters, a start and an end (S and M, or B and D). Set a two-minute timer. Everyone writes as many real words as they can that start with the first letter and end with the second. Score one point per word, plus one for every word nobody else wrote. Then the next person picks two letters. It is the same idea KEYCAPS is built on, and it works at a gate, in a car or around a table after dinner.

Which one should you pick?

If you are flying or driving with other people and want to play together, install KEYCAPS on every phone before you leave and open it once; the Bluetooth race is the rare multiplayer mode that does not need a connection. If you are on your own and want hours of calm levels, Wordscapes. If you want something to do with your hands while you half-watch a movie, a word search app. If you are going somewhere the phones will stay in a bag, pack Bananagrams. Whatever you choose, run the airplane-mode test the night before. For the rest of your phone, our guide to using your phone with no data covers maps, translation and boarding passes, and if the trip is a group one, see the best word game for a group.
