Run with Rito (AI game)

How to play

1. Pick one of your flashcard sets, or paste a text - between 300 and 12,000 characters - and make a new set from it. It’s made just like in the flashcard generator and saved to your flashcards.
2. A question appears at the top with two answers: one right, one wrong. The same answers come down the road towards Rito as two gates, left and right.
3. Use the arrow keys ← → (or A and D) to move Rito into the left or right lane. On a phone, just tap an answer. If Rito runs into the right answer, Rito runs straight through it and on to the next question. A wrong answer - or no choice at all - costs one of three lives, and the game shows you the right one.
4. The game ends after the last question, or when Rito has no lives left. At the end you see your score, your record for the set and the questions to review.

Every quiz question and every flashcard in the set is one round, in random order. For a quiz question, the other answer is one of the quiz’s wrong answers. For a flashcard, the AI writes a separate wrong answer to the same question: one that looks like the right answer, but that your text shows is false. If that answer doesn’t pass the check (more on it below), the card stays out of the game.

The answers come down slowly enough for you to read the question and both answers, and they speed up a little with every right answer. In calm mode, they stop just in front of Rito and wait until you pick a side. Press P or Esc to pause; the game also pauses by itself when you switch tabs.

If the game runs too heavily on your device, tick “Simple look”: instead of a 3D road, the answers slide down a flat track, and the rules stay the same. If reduced motion is turned on in your system settings, calm mode and the simple look are on from the start.

The game also has short sounds: at the start, when Rito changes lanes, for a right and a wrong answer, and at the end. They only play after you click “Start!”, and you can turn them off with the “Sounds” box or the M key.

After a game you can share it: “Share the game” gives you a link where anyone can play this set without an account. You can also start a game from passages collected on different pages with the Memorito extension for Chrome - with the “Game with Rito” button. The game is in the “Account” menu at the top of the page, too.

The game itself doesn’t use AI, so it doesn’t count towards your daily limit. Only making a new set from a text does - just like in the flashcard generator.

The game or flashcards?

When you recall an answer, you remember it better than when you read the same text again - this is called the testing effect. In the game, though, you choose between two ready-made answers, which takes less effort than recalling the answer without a hint. In one study, students reviewed the material at the end of a lecture. Questions where they typed a short answer themselves helped them remember more than reading summaries did - as long as they could answer them. Multiple-choice questions had no such effect.

So treat the game as a light review and a warm-up, not a replacement for flashcards. Try to answer in your head first, and only then read the two answers. Later, go over the questions to review from the end of the game with your flashcards.

Check the questions

The questions and answers come from a set made by AI, and language models make mistakes and can state something false with complete confidence - these are called hallucinations. The generator checks that every card and question comes with a genuine quote from your text. Then the AI picks the right answer again, this time without the answer key, for every quiz question and every flashcard’s pair of answers. Only what comes out the same the second time makes it into the game - and even that doesn’t catch every error. If something looks doubtful, open the set in your flashcards - every answer has a quote from your text, and the quote settles it.

Your data

• You need an account to play - the same one as for the flashcard generator. You sign in with Google or with a code sent to your email - no password needed.
• We don’t store your games on our servers. Your record for each set and the game’s settings (calm mode, simple look, sounds) are kept only in this browser and are never sent anywhere.
• If you share the game, anyone with the link can play the set and see it - without your email address, just like a shared flashcard set. You can stop sharing at any time.
• A new set is made just like in the flashcard generator. We don’t store the text you paste on our servers - it stays only in your browser. The text is processed by an AI model on Cloudflare’s servers (Workers AI), and your account keeps the finished set. Cloudflare states that it doesn’t use this content to train AI models and doesn’t retain prompts or responses once they are no longer needed to handle the request.
• Don’t paste personal data or confidential information.
• You can delete any set, or your whole account, at any time. When you delete your account, this browser forgets your records too. The GDPR also gives you the right to have your data erased (Article 17). You’ll find more in our privacy policy.
