There are three companies that you can buy/sell stocks from. You start with $100, and you are free to buy whatever stock you can afford. By clicking the 'clock' icon below, you can change the market. The changes to the market are randomized logarithmically; meaning there wont be huge changes per click. You can also crumple paper you find on the screen and toss them into the waste bin for money. Rare paper can appear so be sure to look out for them! One last thing, if the price of a company goes below $1, a warning symbol will appear next to it. If the price falls below zero, the business will close and your shares will be deleted!! Be sure to sell them!
