About this app
Coin Change turns the everyday maths of shopping into a game: work out what comes back, then count it out of the till. Every level plays in two beats. First you work out the change — what they paid, minus the price. Get that right and the cashier drawer springs open. Then you build that exact amount from the money actually in the drawer, move it onto the mat, and hand it over. Here is the twist that makes it stick: the drawer is not bottomless. A big silver coin might be sitting there in one level and gone in the next, so the same amount has to come out as several smaller pieces instead. That is the moment children stop counting and start thinking. WHAT'S INSIDE • 100 levels across 8 shops, from the Corner Shop to the Grand Bazaar • 300 questions, every one machine-checked for a fair, solvable answer • Two currencies — dollars and cents, or pounds and pence. Switch any time and your progress follows you. • Coins and notes you can pick up, put back and rearrange • A hint that never strands you: it only suggests a piece that still leaves the rest possible • A Smart Change bonus for paying with the fewest pieces • Stars, scores and a shop map to work through SKILLS IT BUILDS • Subtraction with money • Making the same amount in more than one way • Breaking a large coin into smaller ones when the obvious answer has run out • Mental arithmetic, with a friendly amount of pressure Made for ages 6 to 11, at home or in the classroom. No account, no sign-up and no timers you cannot pause. COIN CHANGE PRO Levels 1 to 10 are free to play. A single one-time purchase unlocks all 100 levels and removes every advert — there is no subscription.
