Card Dealer Simulator

You start with $1,000 in cash and run a card shop for one day. 15 customers visit — some want to buy cards from you, others want to sell you their cards. Each customer has a personality type (collector, flipper, whale, etc.) that affects their willingness to pay and negotiate. Accept deals, pass on bad ones, or counter-offer to get a better price. Your goal is to maximize total assets (cash + inventory value) by the end of the day.

Yes — every card and estimated value comes from CardVault's database of 6,200+ real sports cards. Customer offer prices are based on real market values adjusted by their customer type. A collector might overpay for a card they love, while a flipper will try to get the lowest price possible.

Each customer has a patience level (1-3 rounds) based on their type. You can enter a counter-offer and they'll respond. If your counter is reasonable, they may accept. If it's too aggressive, they'll meet you halfway. Push too hard and they walk away. Different customer types have different tolerance — whales are patient, flippers aren't.

Yes — the customer sequence and cards are seeded by today's date, so everyone faces the same customers and deals. This makes it fair to compare scores. Tomorrow brings a completely new set of customers and cards.

Buy cards below market value and sell above. Pay attention to customer types — a whale will overpay while a flipper won't. Don't be afraid to pass on bad deals. Keep enough cash to buy good deals when they come. Building inventory is fine if you buy below market — your final score counts unsold inventory at market value.
