Ten30: Learning Quizzes

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.
