There was a similar trading game that I played on the ASX (Australian Stock Exchange) when I was in High School. I tried to do it by just buying regular stocks, but when I looked at the leaderboard the people at the top were always buying 100,000's of a penny stock and selling when it went up. So they could win or lose the game based on luck and how much they bought of that particular penny stock within the game window. Looking back now on that stock trading game, especially because it had a fixed window of time, it really favoured taking the big risks with these penny stocks. You weren't playing with your own money, and you weren't playing the long game either as there was a time you were effectively cashed out. I'm not sure that's the sort of wise saving & investing for the long term that one should be teaching teens/children. It's more for the ASX itself to train another generation of traders, which will make the business richer.
