What They Don't Teach You at Harvard Business School

by Mark H. McCormack

  • Productivity
  • Startups

The Subtle Art of Not Giving a F*ck

by Mark Manson

  • Self-development
  • Assertiveness
  • Boundaries

This book argues that a good life comes not from chasing endless positivity but from choosing your struggles and values with care. Through Mark Manson's blunt, story-driven philosophy, you'll practice telling meaningful problems from trivial ones, taking responsibility without blame, and facing failure and mortality as sources of clarity rather than fear.

How it works

Three steps from a book you liked to a book you actually use.

01

Pick a book

One you have read, or one you keep meaning to. No upload needed: the world is already built and opens in your browser.

02

Walk its world

Every part of the book is a map. Every character quizzes you on one of its ideas, and a boss guards the big ones.

03

Come back until it sticks

Questions you miss return in rematches and boss fights. Spaced repetition, wearing a costume.

Why a game works where a highlighter fails

The mechanics are the study method. Active recall and repetition, with a reason to keep going.

Recall beats re-reading

Highlighting feels productive and fades in weeks. Pulling an idea out of your own head is what makes it stay. Every battle is that pull.

Ideas tested, not just underlined

The questions are about the argument of the book, not trivia, and each one comes with an explanation. Miss it and you learn it on the spot.

Ten minutes a day

A map is a short session. Progress, XP and streaks are saved to your account, so the book keeps working long after you finished it.

Five ways to play

Explore the overworld RPG, climb the tower where every right answer refuels the climb, drill the questions as flashcards, practise them in a mini-game or duel a friend on them.

Questions

Are these the actual books?
No. Each world is a quiz game generated from the ideas in a book: maps, characters and hundreds of multiple-choice questions with explanations. You still want the book itself, and every page links to where you can get it.
Is it free?
Every book page has a demo you can play without an account. With a free account you keep your progress; free worlds are unlimited and premium worlds come with a preview (5 battles, 10 tower questions and 10 mini-game questions each, plus their flashcards). Pro unlocks everything, from $4.99 a week.
Do I need to have read the book?
It works either way. After reading, the game is spaced repetition for what you learned. Before reading, the explanations turn it into a fast tour of the main ideas, and a good way to decide whether the book is for you.
Does my demo progress carry over?
Yes. Sign up from inside a game and the characters you beat, your XP and your best tower stage move to your account.
Do you earn from the book links?
Some of them are affiliate links. If you buy through one we may earn a small commission at no extra cost to you. It helps keep the free worlds free.
Can I do this with my own books?
Yes. Pro turns any EPUB or PDF you own into a world of its own: your notes, your language, your questions.

Your bookshelf, as a game.

Pick the book you most want to remember and play through it instead of re-reading it.
