- Practise: flip each card and mark it Known or Again.
- Known cards move up a box and are shown less often.
Worked example

Questions
How does the spaced repetition work?
Each card sits in one of 5 Leitner boxes. A correct answer moves it up a box with a longer wait, and a miss sends it back to box 1, due again now. Two correct answers move a card from box 1 to box 3, next due in 4 days.
Where are my decks saved?
In this browser only, with no account or sync. Export a CSV or JSON backup to move decks to another device or browser.
How strict is the quiz when I type an answer?
It ignores differences in letter case, accents and punctuation, and accepts listed alternative answers, so small formatting differences are not marked wrong.
