FOR MED STUDENTS ON ANKI

The game you play by doing your cards.

A village game connected to your Anki decks. Your wheat, milk and cheese come from your reviews, so the village grows when you study.

11 P.M. SIX WEEKS BEFORE STEP

You know Anki works.
Opening it is the hard part.

The exam gets closer. The count explodes. You open the app, do a couple of cards, and close it. Tomorrow the number is bigger, and opening it gets harder.

Example count. You know yours.

THE OBVIOUS OBJECTION

A game before your exam sounds like a terrible idea.

A normal game would steal your study time. So test this one. Take a guess.

You play for one full hour and review 0 cards. How much does your wheat grow?

HOW IT STAYS HONEST

Three rules you can check yourself.

12 cards. One wheat field.

That's the price in the Anki add-on, and your first bakery takes 12 more to build. On iPhone, the step can vary with your daily rhythm: a bigger day can mean a smaller step per card.

Press Again. Your wheat still grows.

Every answer moves your crops, whichever button you press. So you can keep rating your memory honestly, and your schedule stays useful.

Your decks, on your laptop and your phone.

Keep the decks you already use. In Anki, the add-on runs alongside your reviews. On iPhone, your decks arrive through that add-on, or you import an .apkg.

FROM THE PEOPLE WHO USE IT

From “dread” to “excited”.

“I used to dread it so much and now I get excited to do Anki!”

Godot, med school

“downloaded this to study for STEP1 and its been a game changer.”

seal, Step 1

“I am actually doing Anki pretty much daily because it makes it fun and you have to do cards to grow your village.”

Player review, MD 2

“This really helped me get out of procrastinating for my MCAT.”

Player review, MCAT

“In residency trying to get back into Anki for ATI- gamification is the only thing that makes it bearable!”

Player review, residency

I went from roughly 50 to 200 daily reviews. That's one person, me. Your own test is the one that counts.

Marceau, who built it

Public reviews of the Anki add-on, quoted word for word, from 2026. The add-on has offered in-game rewards for writing a review, so read them as player voices and run your own test.

YOUR OWN TEST

Tonight, do your cards.
Then look at your village.

It's a beta, so expect a few bugs. One evening will tell you if it makes you want to open your cards.

Before you install it.

Will this steal my study time?

It can. Some players say the game itself pulled them in. What you build costs reviews, so playing keeps sending you back to your cards. If you catch yourself playing more than reviewing, close it.

I already do my cards every day. Do I need this?

Probably not. One very motivated reviewer told us it slowed them down. This is for the nights you can't get yourself to open the app.

Will it raise my score?

We make no score promise and we have no exam data. Anki does the memory work. The game's job is getting you to sit down and open it.

Does it change my cards or my Anki schedule?

Answering cards leaves your scheduler as it is. The one tool we found that moves due dates is an optional backlog spreader you launch yourself, and Ctrl+Z undoes it.

Is there AI in it?

Yes. Some art was enhanced with AI, and the Sage is an AI tutor that can explain a card another way. Check anything medical against your own sources.

Is it stable?

It's a beta. Slowdowns and bugs are the most common complaint, especially on older laptops. Tell us on Discord and we'll look.

I'm not in med school. Does it work for me?

Yes. It works with any deck: languages, law, whatever you're memorizing. Med students are simply who this page is written for.
