Choose your game mode (Timed Market or Rush Hour) and difficulty.
A customer arrives at your stall with an item and hands you a bill.
The game shows you the item's price, the bill received, and the change you owe.
Click denomination buttons (coins and bills) to build up the correct change amount.
Watch the progress bar — when it turns green and you've hit the exact amount, the customer is served!
If you give too much change, the bar turns red — click items in the change tray to remove them.
Use 'Undo' to remove the last denomination added, or 'Reset' to clear all.
In Rush Hour mode, a countdown bar shows how long you have before the customer leaves.
Cashier Simulation
Step behind the counter — customers bring items to buy and hand over a bill. You select coins and bills to give back the correct change.
Escalating Difficulty
Easy mode uses coins only for change under $1. Medium adds the $1 coin for transactions up to $4.49. Hard introduces the $5 bill for change up to $7.99.
Two Exciting Modes
Timed Market races you to serve as many customers as possible in 60 seconds. Rush Hour gives you 3 lives with a per-customer countdown — let one go and lose a life!
Live Progress Bar
A bar fills up as you add change, turning green when you hit the target exactly. Overshoot and it turns red — remove denominations to correct yourself.
Coins and Bills
Practice with penny, nickel, dime, quarter, half-dollar, $1 coin, and the $5 bill across difficulty levels.
Market Vendor is a cashier-simulation game where players run a market stall and give correct change to a stream of customers. Unlike games that ask you to pay for items, this one puts you on the other side of the counter — building the correct change amount from coins and bills. The game features three difficulty levels that introduce more denomination types and larger change amounts, and two modes: a 60-second sprint or a survival challenge with limited lives.
In Easy mode the customer always pays with a $1 bill for items under $1. In Medium they pay $5 for items costing $0.51–$4.99. In Hard they pay $10 for items costing $2.01–$9.99.
The progress bar turns red and a 'Too much change!' message appears. Click any coin or bill in the change tray to remove it, or press Undo/Reset to fix your selection.
Rush Hour gives you 3 lives and shows a countdown timer for each customer. If you don't give correct change before the timer runs out, the customer leaves and you lose a life. Lose all 3 lives and the game ends.
Your score equals the total number of customers successfully served with correct change. Each correct transaction adds 1 to your score.
Easy: 1¢, 5¢, 10¢, 25¢. Medium adds 50¢ and the $1 coin. Hard further adds the $5 bill.
Yes! The cashier role is more cognitively demanding than simply paying — players must calculate the change owed and then build it from denominations, combining arithmetic and strategic thinking.
