About Small Universe

Teaching English through play, not homework.

Small Universe is a free English learning game for children ages 3–10. Kids guide an alien companion through four planets, picking up vocabulary through 17 different mini-games instead of flashcards or word lists.

Why we built this

Most language apps for kids are flashcard drills with cartoon paint on top. We wanted a game where kids don't realize they're learning until they already have.

Small Universe started because my own kids hated every English app I tried. So I built one that actually uses the research instead of just citing it on a landing page.

The research behind it

The game mechanics come from real research in language acquisition, memory, and child psychology:

Krashen

Comprehensible Input — learn through context, not translation

Ebbinghaus

Spaced repetition — optimal review intervals for long-term memory

Dweck

Growth mindset — mistakes celebrated as progress, never punished

Vygotsky

Zone of Proximal Development — scaffolding that fades as competence builds

Bjork

Desirable difficulties — interleaved practice for deeper retention

Nation

Four Strands — 17 game types covering all four learning strands
