## What is Coin Bazaar?

Coin Bazaar turns two big computer-science ideas — recursion and dynamic programming — into a warm, tap-only market game. No reading required, no typing needed.

Every price on the stall is built from smaller prices. Pay 1 coin, then pay the rest the best way you already worked out. Fill your way up the ladder to the golden star at the top and the whole market lights up.

FOUR CHALLENGES, ONE BIG IDEA
• FAIR TRADE — pay each price with the fewest coins. Tap a coin to try it, compare, then pick the smallest total.
• BUSY BAZAAR — bigger prices, where the same small answers keep coming back. Work each one out once and reuse it.
• TRICKY COINS — meet Grabby the Raccoon. He always grabs the biggest coin, and here that makes him pay MORE. Beat him by planning ahead.
• COUNT THE WAYS — how many different ways can you pay? Add up the ways below and watch the numbers grow.

THE MOMENT IT CLICKS
Solve a ladder and the game shows you what you just did: your handful of steps racing the slow way that recomputes everything from scratch — often 15 times more work. Or Grabby counting out five coins while you paid with three. That contrast IS the lesson, and children feel clever rather than lectured.

PLAY TOGETHER
• Two players share one device on the same market — a "pass it over, no peeking" screen keeps it fair, and the faster solver takes the round. Best of three.
• Or race Penny, a friendly computer opponent you can genuinely beat.

FOR FAMILIES
• Free forever: the whole Fair Trade challenge, plus every 2-Player and vs Computer match.
• One optional, one-time unlock adds the solo Busy Bazaar, Tricky Coins and Count-the-Ways challenges — behind a parental gate. No ads. No subscriptions.
• 100% offline. No accounts, no sign-in, no data collected.
• 11 languages with full right-to-left support.
• Earn stars and stock your own market stall as you go.

Every puzzle is guaranteed solvable and mistakes are gentle — the price tag just blushes and you try again. Made for curious children aged 6 and up, and for grown-ups who never got to meet these ideas this way.
