A popular game I used to play on forums was known as the investment game. The game rules are pretty straightforward.
- Ten stocks are advertised for sale on the opening day.
- There will be a sale price and a purchase price. The sale price is the price it costs to buy the stock and purchase price is the price to sell back to the market.
- Each stock has a maximum cap of stocks that can be sold so trading among the participants typically happens once stocks become few.
- Some participants may work out deals to trade with each other that may be more financially advantageous than buying directly from the market.
- The stocks values are updated daily so that each person can determine their total wealth.
- Stocks may be bought or sold to an individual or to the bank.
- Stock sales or trades to individuals must be set at a mutually agreed upon quantity (and price if applicable).
- Stock sales to the market will be at the seller's discretion of quantity but at the advertised market (purchase) price
- After ten days, the individual with the most wealth is the winner.
- All players start with $10,000
- No one has to send all or any of their money
- Deficit spending is not permitted
The game needs at least five players to play.
