Read full description

Grammar that kids actually beg to do. Designed for iPad. Welcome to Grammar Quest — a world where grammar IS the game. Choose your Alphabeast starter, land at a handcrafted pixel-art island, and battle challengers by answering grammar questions drawn directly from your country's curriculum. Get the answer right? Your beast unleashes Verb Rush or Punctuation Pulse. Wrong? A friendly tutor explains why — then you try again. It looks like an adventure game. It teaches like a private tutor. It's both. FREE TO PLAY Download free. Try the whole of Year 1 with no limits — every concept, every battle, every town. Three sample battles per higher year so you can taste-test anything. ONE-TIME UNLOCK — $9.99 Unlock the entire game forever. No subscriptions. No ads. No data tracking. Apple Family Sharing supported — siblings learn for one price. • Years 1 through 9 (Prep / Kindergarten / Reception through to Year 9) • 4,500+ grammar challenges across 180 concepts • 20 towns per year level, 4 challengers + 1 Word Warden boss per town. • 30+ collectable Alphabeasts across six elemental types • All four curriculum packs • All recorded voice narration packs • Every town, every concept, every quest unlocked • Funny characters and animals in each town with their own facts or puns to share!

FOUR CURRICULUMS, ONE GAME Switch curriculum in Settings — standard codes, terminology and spelling adapt automatically. • AUSTRALIA — Australian Curriculum v9.0 (ACARA). Maps directly to NESA, VCAA, QCAA and SCSA outcomes. "Full stops", "colour", "favourite", "speech marks". • UNITED STATES — Common Core ELA. Grades K through 9.

EARLY LEARNER VOICE PACK (Prep / Kindy / Reception through Year 2) Beautifully recorded human narration reads every question, every word card, every story prompt aloud. Built for kids who are still building reading fluency — so they can play, learn and progress before they can read every word on their own. WHY IT WORKS Children practise what they see at school every day, but with gamification. Every wrong answer becomes a teaching moment, not a punishment. The challenge curve mirrors the curriculum — so by the time a Year 3 student finishes the Year 3 islands, they've practised every grammar concept their teacher will test that year. 13 QUESTION STYLES Multiple choice, sort, build, fix, fill the blank, true/false, sentence transform, passage questions, sentence combining, word builder, match, spot the error, odd one out. Variety keeps it fresh. SAFE FOR KIDS, SAFE FOR PARENTS • No ads, ever • No data collected — fully on-device • No third-party tracking • No social features, no chat • One-time IAP only; no subscriptions • Three save slots per year — siblings welcome • Plays fully offline OPTIONAL EXTRAS • Game Center: 3 leaderboards, 12 achievements • Parent Report dashboard — see exactly which concepts have been mastered • Daily streak reminder (opt-in) Designed for iPad.
