TinyMinds Quiz – Mobile Quiz Game with Heroes, Levels and School Leaderboards

Our client had a complete game concept, a cast of characters and a Figma design – what they needed was a team to turn it into a polished, live mobile game on both stores. We built TinyMinds as a cross-platform React Native app on a Supabase backend, working in short iterations with the client reviewing every build and sending structured feedback rounds that we turned around sprint by sprint. The game is driven by a layered engagement system: ten-question rounds with a ticking clock and power-ups, eight heroes with their own lives, levels and stars, a ninth unlockable hero that generates diamonds, daily and weekly goals, ticket-based mini quests on narrow topics, and weekly rewards. On top sit the leaderboards – individual weekly XP rankings and a separate school leaderboard, so every correct answer also counts for the player's school. Progress syncs through Game Center and Google Play Games with no account creation, and the app works offline with conflict-safe sync. For the client we built a web admin to manage the question bank, see correct-answer percentages and question counts, handle mini quests separately, moderate player names and remove users on request. Monetisation combines rewarded video ads, one-off shop packs and a monthly supporter subscription, all integrated and reviewed for both stores. We took the game through App Store and Google Play review, set up the custom domain, legal pages and a Duolingo-style landing page, and now monitor ad delivery and user behaviour in production – catching and fixing issues like ad-network load failures before they hurt revenue.
