Loading the demo world…
This world was generated from a real textbook. ← → to move, Space to jump, ↓ + Space to drop through. Use the on-screen controls to run and jump.
Sound familiar?
Three things every student knows, and what is really behind them.
It is hard to start
The chapter is open, the phone is closer, and twenty minutes pass before the first line. Not laziness: a page of text demands a decision every minute, and a tired brain refuses.
A game starts in one tap, and the first question is already waiting for you.
It is boring
A third read of the same page puts the brain on autopilot. Nothing asks anything of you, and nothing happens when you get something right.
Every screen asks you something, and something happens when you answer.
It does not stick
Highlighting and rereading feel productive, but they train you to recognise a sentence, not to produce it. The exam gives you a blank line, not a sentence to recognise.
You keep what you had to recall on your own. Here, every answer is exactly that.
How it turns around
One upload, then the material comes to you.
Upload what you have to learn
A textbook, lecture notes, a summary, a past paper: any PDF or EPUB up to 50 MB, in any language, on any subject.
A world is written from it
In a few minutes you get maps, characters and multiple-choice questions on every key idea, each explained. The RPG, Tower Climb, the mini-games, the duels and the flashcard deck all share them.
Play, and the questions come to you
Walk the map and battle the characters. Win, and the next map opens; miss a question, and it comes back until you get it right.
Why playing works better than rereading
None of this is our idea. The research on learning has said it for years; we only made it something you want to do.
Retrieval practice
Every battle is a test, and testing beats rereading.
A 2013 review of ten study techniques rated practice testing and spacing the most useful, rereading and highlighting among the least. Tested students remembered more a week later than rereaders.
Dunlosky et al., 2013Spacing
Missed questions come back later, and flashcards are scheduled over days.
Across 317 experiments, spaced study beat one sitting, and the best gap grew with how long the memory had to last. Cramming works for tomorrow and fails in four weeks.
Cepeda et al., 2006Feedback right away
Every answer shows you the right one, and why.
Feedback after a test raises what you keep, and not only on the wrong answers: it also fixes the right ones you were unsure of, which slip away first.
Butler, Karpicke & Roediger, 2008Motivation you can feel
Levels, bosses and streaks make your progress visible.
People stick with what makes them feel competent and lets them choose. A rising level and a fallen boss are competence you can see; five modes are the choice.

What you get
One upload, five games, and nothing that gets between you and the material.
Five ways to study one upload
The RPG for an evening, the tower for ten minutes, a mini-game in a queue, a duel with a friend at lunch, flashcards on the bus. Same questions, shared progress.
Missed questions come back
A question you got wrong returns in rematches and boss fights, and a card graded Again comes round sooner. What you do not know yet gets the most practice.
Progress you can see
XP and levels per world, bosses beaten, a day streak, and achievements across every world you play. One look at the dashboard says how far you are.
Your subject, your language
Medicine, law, history, economics, a language course: if it is written down, it can be played, and the questions come out in the document’s language.

Start a 25-minute block in the free study timer: a pixel room, your character in the armchair, a cat on the sill. Every block earns XP and keeps your streak.
