FlashBoss

spaced-repetition with boss fights

Build a real vocabulary in English, German, Spanish, Italian, or Esperanto — then prove it in a duel.

The FlashBoss approach

The target vocabulary is grouped into thematic clusters with progressively longer, and more complex example sentences and explanatory notes. Each cluster ends in a boss fight.

Before you can defeat the boss, you must answer to the words you found most challenging. Win, and those cards graduate.

The cards themselves
