A free coin counting game that feels like running a real shop
Coin Market is a money counting game built around a real shop-keeper loop instead of a bare drag-a-coin-to-match-the-amount exercise. A customer walks up to your market stall, tells you what they want and what it costs, and you build the exact payment out of coins and bills by clicking them into your tray. Six difficulty tiers move from counting with a single coin type, up through two coin types, all coins mixed, coins plus bills, making change for a customer who overpays, and an advanced mode with multi-item word problems, so the same game genuinely serves a wide age range, roughly kindergarten through 4th grade, instead of needing a separate page per grade.
Four real currencies are supported: US Dollars, British Pounds, Australian Dollars, and Euros, each with their own accurate coin and bill denominations. US Dollars is unlocked from the start, and the other three unlock as you earn Coin Market's own 🪙 coins by serving customers correctly, along with a few cosmetic shop styles, so there's a real progression system tied to actually practicing the skill, not just a raw score. Every payment is checked by total value, not by matching one exact combination of coins, so any correct combination of coins and bills is accepted.
Coin Market is free, works with a mouse, touchscreen, or keyboard, needs no download or account, and saves your progress locally in your own browser. See the Parents & Safety page for the full privacy details, or browse the rest of the Math Games hub.
