This is practically the same game as Mansion: Impossible. You are a real estate agent. You buy houses and resell them for a higher price. You have a certain amount of money and cannot buy houses that cost more than you have. When a house you can buy appears, click on it to buy it. You'll see the price of the house above it. Your goal is to sell the house for the highest price possible. It's quite easy because all prices behave the same way: They grow until they reach their peak and then stat to fall. Just catch the peak moment and click on the house once again to sell it.
