Ten islands. One hundred levels. One thousand questions. Quiz Island is a family trivia adventure that grows with you. Sail from Jungle Kingdom to Champion's Summit, clearing a winding trail of ten levels on every island, earning stars and gems as you go. BUILT FOR THE WHOLE FAMILY — REALLY Most quiz apps for children stay easy. This one climbs. Level 1 of every island is comfortable for a seven-year-old. By level 10 the questions are genuinely hard for a well-read adult — real names, real numbers, real facts. The words stay simple the whole way up, so a child can always read the question even when the answer is tough. Play it together and see who gets further. TEN ADVENTURES TO EXPLORE • Jungle Kingdom — animals and the wild • Galaxy Quest — planets, stars and space travel • Dino Valley — the age of the dinosaurs • Ocean Paradise — reefs, whales and the deep • Explorer's Trail — countries, flags and landmarks • Blossom Garden — flowers, trees and growing things • Science Lab — how the world works • Brain Castle — logic, numbers and puzzles • Ancient Kingdom — pharaohs, empires and lost cities • Champion's Summit — the grand challenge, drawn from all nine LEARN SOMETHING EVERY TIME Every single question comes with a "Did you know?" fact — not a repeat of the answer, but something new and surprising about it. A thousand questions means a thousand small discoveries. COLLECT AND KEEP Spend your gems on 167 hand-drawn stickers and arrange them across a 25-page sticker book, exactly how you like.
