Ten30: Learning Quizzes

Math, spelling, geography, vocabulary, and science — ten questions at a time, in a calm pastel design. No ads, no tracking, ever. See how far you get.

Ten30 — learning, ten questions at a time.

Ten30 is a collection of five beautifully simple learning games built around one idea: ten questions, thirty seconds. Short enough for a coffee break, sharp enough to actually teach you something.

Five subjects, one calm design • Math — arithmetic and number sense, from warm-ups to mental-math challenges • Spelling — listen and spell, with decoys that make you think • Geography — countries, capitals, and flags across every region • Vocabulary — definitions, synonyms, and words in context • Science — biology, astronomy, anatomy, the periodic table, and more

How it works Each round is ten questions against a thirty-second clock. Answer well and you earn mastery stars — three tiers per level, with the top star reserved for a perfect score AND speed. Levels climb from easy to genuinely tough, so there's always a next rung.

Made to come back to • Daily challenge — a fresh set every day, with streaks to keep • Practice mode — untimed, no pressure, just learning • Progress that follows you — play as a guest, or make an account to sync across devices • Works offline — on a plane, a subway, anywhere

No ads. No tracking. No selling your data. Ten30 is a quiet place to learn — just you, the questions, and the clock.
