Card Tycoon

Card Tycoon is a card market trading simulator where you start with $500 and try to grow your portfolio by buying and selling sports cards over 10 rounds. Each round, the market shows 3 cards at current prices. You decide when to buy, hold, and sell based on price movements. Your final score is your total value (cash + portfolio) after all 10 rounds.

Card prices fluctuate each round by up to 20% in either direction, with a slight upward bias mimicking real card market trends. Some cards will spike in value while others drop. The key to winning is buying undervalued cards and selling when prices peak — just like real card flipping.

The Daily Challenge uses the same card market for everyone on a given day, so you can compare your trading skills with other players. The Random Market mode generates a fresh set of cards each game, letting you practice different strategies without competing on the same board.

Your grade is based on total profit: S (Card Mogul, +$200+), A (Smart Investor, +$100-199), B (Savvy Trader, +$50-99), C (Careful Collector, $0-49), D (Learning Curve, -$1 to -$100), F (Bust, worse than -$100). The game teaches real card market dynamics — when to buy the dip, when to take profits, and when to hold.

Card Tycoon teaches the fundamentals of card flipping and investing: buy when prices are low (dips), sell into strength (rallies), diversify across sports, and manage your cash reserves so you can capitalize on deals. The same principles apply whether you are flipping cards on eBay or buying at card shows.
