Can you learn English by playing video games? What the research says (2026)

"Stop playing games and go study."

Most of us have heard some version of that line. Which makes it awkward that when researchers went and measured it, the kids who played the most scored highest on their English tests.

Here is what they actually did, and what it means for you.

What did the study actually do?

Two researchers in Sweden, Liss Kerstin Sylvén and Pia Sundqvist, got 86 kids aged 11 and 12 to keep a diary for a week.

Every day the kids wrote down how long they spent on seven things in English. Books. Newspapers. TV. Films. The internet. Music. Games.

Then they all sat three tests. Vocabulary, reading, listening. Nothing about games on any of them.

The kids who gamed five or more hours a week scored highest. The ones who gamed sometimes came second. The ones who never gamed came last.

That order held on all three tests. The researchers went looking for something else that might explain it, and did not find anything.

The games they named were Call of Duty, Counter-Strike, World of Warcraft, The Sims, Restaurant City and Zoo Tycoon.

Why would Call of Duty teach anyone English?

Because in Sweden, games are not translated.

Nobody dubs World of Warcraft into Swedish. So an eleven-year-old playing five hours a week is reading five hours of English quest text, hearing five hours of English voice acting, and typing English to strangers in chat.

That is more English than school gives them. And nobody had to make them do it.

If you have ever wondered why your kid can quote a game in English but freezes in an English class, that is the answer.

So nothing mysterious is happening here. Games are not doing something clever to your brain. You are just getting a lot of English, in a form you actually come back to tomorrow.

Which is why the screen time argument at home tends to change shape once the game is in English.

“My son was addicted to Roblox, and it used to worry me. Now he’s learning English while he plays games, so I feel very relieved! He finds GameStudy as fun as Roblox, so he mostly plays on GameStudy now.”

Does it still work if the game is built to teach?

Better, and this is a different kind of evidence.

The Swedish study watched what kids already did. It cannot tell you whether gaming caused the gap, or whether kids who were already good at English picked English games. Both are probably a bit true.

So other researchers ran real experiments. You take one group and give them a language game. You take another group and teach them normally. You test everybody before and after.

In 2025, a team pooled 38 of those experiments covering more than 4,000 learners and found the games came out well ahead. The clearest gains were in vocabulary and pronunciation.

That is the version with cause and effect in it.

The one thing those games never asked for

Look again at what the Swedish kids did all week. Read quest text. Listened to voice lines. Typed in chat.

All of that is English going in. None of it is English coming out.

So the gains landed exactly where you would expect. Vocabulary, reading, listening. The parts you can build with your mouth shut. Speaking is the one part you cannot absorb, because there is no version of getting good at it that does not involve doing it.

That gap is the reason GameStudy exists. The games are built so the only way forward is talking, and everything else in the app is there to make talking easier when you are stuck:

• Hints show you something you could say next, in English and in your own language, so you are never sitting in silence while a character waits.
• Captions show you what was just said, so one missed word does not end the conversation.
• Translations sit underneath, so you can check a meaning without leaving the game.

That is the difference between a game that happens to be in English and a game built to get you speaking it.

What actually makes a word stick?

Three findings, none of them about games, all pointing the same direction.

You keep the words you needed. Vocabulary researchers have a rule of thumb called involvement load. A word sticks in proportion to how badly the task made you need it. A review of 78 studies found the tasks that won were the ones that made learners produce the word, not just read it.

You keep the words you said out loud. Read a word aloud instead of silently and you recognize it later about 10 to 20 percent more often. It is one of the sturdiest findings in memory research. Whispering counts. Mouthing counts.

You keep the words that arrived through more than one door. Across seven reviews covering 136 studies, words met with pictures and sound beat words met as text on a page. Beginners gained the most.

Read those three together and they describe something quite specific. Not a word list. A situation you are standing in, with a voice in your ear, a reason to open your mouth, and something that happens because you did.

That is why GameStudy is played by talking. You say the thing out loud to a character who answers you, in a story you want to see the end of. Spy, Word Rush, Cafe Life, Missions, Survival Island. Games first, with the English underneath.

“I am an introvert, so I hardly spoke at a language school. Since Kai is an AI, there is no pressure and I end up talking a lot!”

“My vocabulary is pretty thin, but the words that come up in the games stick with me, and I find myself actually using them in free conversation. It has worked better than I expected.”

Should you play?

If you already game, this is close to free. The hours are going anyway. Spending some of them in a game that makes you talk gets you the kind of practice you would otherwise have to book and pay for.

And if you never game, but there is a language app sitting on your phone that you stopped opening months ago, the argument is simpler.

There was probably nothing wrong with the lessons. What went wrong is that studying was one more thing on the list, and every night it lost to something easier.

A game never has to win that fight, because it is not on the list. It is the thing you were going to do anyway.

That is the part a game fixes. Not the teaching. The showing up. And showing up is the entire thing the research measured!
