ha! that reminds me of my Economy class in high school. We used to do a weekly game, where in the beginning of the year we'd have a certain amount of money, and we'd have to buy stock. The teacher would every week update us with the latest stock information, and based on that we'd have to make decisions. The person with the biggest amount of money at the end of the year won.

So I picked stock of a company which was basically bankrupt already, but was still on the stock market (why I don't know, I'm not an expert.) I think the stock was £0.02. So I waited a few weeks, and it happened to be at £0.05. I sold everything, didn't do anything for the rest of the year, and won. Didn't make the game very exciting, but at 15 years old I mainly cared for winning :)

I did much the same right after WalMart crashed. Bought (hypothetical) shares for $0.02 a share; won the game by at least four orders of magnitude...

When we did a stock market game in high school, we weren't allowed to use penny stocks.

I was so excited to find stocks that were doubling or tripling daily, only to realize how worthless it'd be in real life.

If anyone out there is a trader that works with penny stocks, I'd love to hear your insight. Is it possible to "game the system" by working with just a few (10-100) shares, instead of large holdings?

The main issue with small odd lots of penny stocks is that you'd be killed by the commission costs. Most high school "stock market" simulations ignore transaction costs to keep things simple.
