Flashcard Vivarium (Roblox)
A cosy greenhouse world for studying real flashcards - Maths, Biology, Chemistry, Physics and more - with spaced repetition, Study Points, a Rebirth altar and a weekly Anki-vs-Quizlet rivalry. The study-with-me room that went viral.
What makes it different: the flashcards are real. Pick a deck, flip cards, and mark each one Got it or Need to review - the game runs spaced repetition, so the cards you miss come back first next session, and your progress saves between visits.
How studying works
- 1Pick a deck
Maths, Biology, Chemistry, Physics, General Knowledge - plus the Vivarium Creatures deck for learning the world's own critters.
- 2Flip and self-mark
Read the card, check the answer, mark it Got it or Need to review. Honest marking is the whole point - the algorithm only works if you admit what you missed.
- 3Let repetition do its job
Tricky cards resurface first next time - classic spaced repetition wrapped in a garden instead of an app.
- 4Finish sessions for Study Points
Reviewing cards and completing sessions pays Study Points, with a lucky bonus roll every 15 minutes just for being there.
Progression
