Run your own shop! Sort needs vs. wants, classify goods vs. services, and make smart supply & demand calls to earn coins.
Pick your grade:
Tap the right answer (or press 1–4). Every correct call serves a customer and earns coins. Keep a streak for bonus coins — but a wrong answer costs a bit of patience. Run out of patience and the shop closes! The game learns your weak skill and gives you more practice there. 🪙
