Bear and Bull

Trigger warning: This game was vibecoded and is mainly made with support of AI

Bear & Bull Card Game is a strategy game where you compete to build the most wealth over 8 rounds, either against a computer or another player on the same device (couch mode). You trade stocks, cryptocurrencies, and gold, take loans, and use special tools to outsmart your opponent. Wealth is your cash plus the value of your stocks and gold, minus loans and shorted stock losses. Here’s how it works:

Game Flow

Each round has six phases:

1. Trading: Buy or sell stocks, crypto, or gold, take loans, pay debts, or use tools. In couch mode, Player 1 trades, clicks "Done Trading," then Player 2 trades. Against the computer, it trades after you.
2. News: A random event changes prices (e.g., Bull Market: stocks up 20%, crypto up 50%, gold down 10%).
3. Volatility: Sets how much prices swing in the next phase (e.g., High Volatility: bigger swings, especially for crypto).
4. Report: One stock’s earnings report changes its price (e.g., Strong Quarter: stock up 10%, crypto up 30%).
5. Drift: All prices wiggle randomly (stocks ±2.5%, crypto ±7.5%, gold ±2%), loans gain 10% interest, and shorted stocks adjust cash.
6. End: Dividend-paying stocks (like QuantumSoft) pay $10 per share, and the round ends. The computer’s trades show up here.

Key Actions

• Stocks & Crypto: Buy or sell 24 stocks (Tech, Health, Energy, Finance, Retail, Crypto). Crypto swings 3x more (e.g., a 20% stock jump is a 60% crypto jump). Some stocks pay dividends.
• Gold: Buy or sell gold (starts at $1000) for a safer investment with smaller price changes.
• Loans: Borrow $5000 to trade more, but pay 10% interest each round. Repay $5000 chunks when you can.
  • Example: Borrow $5000, buy stocks. Next round, owe $5500 ($500 interest taken from cash).
• Sell Everything: Cash out all stocks and gold at current prices.

Special Moves

• Leverage: Boosts a stock buy’s gains or losses (5x or 10x). Pick leverage, buy a stock, and its price swings multiply. Resets after one buy.
  • Example: Buy a $500 stock with 5x leverage. If it hits $550, it’s worth $750 ($50 × 5). If it drops to $450, it’s worth $250 ($50 × 5 loss).
• Shorting a Stock: Bet a stock’s price will fall. You “borrow” a share, sell it, and owe the price difference later. Profit if the price drops, lose if it rises.
  • Example: Short a $500 stock. If it falls to $400, you gain $100. If it rises to $600, you lose $100.
• >span class="css-1jxf684 r-bcqeeo r-1ttztb7 r-qvutc0 r-poiln3 r-a8ghvy">: Get a tip about a stock’s price change soon (e.g., “Buy Bitcoin, it’ll jump 50% in 2 steps”). Stars the stock on the grid.
• Tech Analytics ($2000): Get ongoing tips about stock changes a few steps ahead, lasting all game (e.g., “Avoid MediLife, it’ll drop 10% soon”).

Strategy Tips

• Leverage: Use with tips for big wins, but it’s risky if prices fall.
• Shorting: Short stocks you think will crash (e.g., Health stocks in a Healthcare Crisis), but avoid if prices might soar.
• Loans: Borrow to buy more, but repay fast to avoid interest piling up.
• Crypto: Big wins or losses due to wild swings—use tips to time buys.
• Gold: Safer than stocks, good during crashes.
• Tips: Insider Info and Analytics help you plan buys or shorts, especially for crypto.

Winning

After 8 rounds, the player with the most wealth (cash + stocks + gold - loans - short losses) wins. The game shows both players’ wealth and declares the winner.
