After the business rooms are available, begin hiring people to bring you more profit. Try to unlock all three rooms as soon as possible. However, do not fill them with cheap and lazy workers. Each worker category has different jobs available. The more expensive a worker is, the better he or she will perform. If you do not have money or are saving it, hire all the workers possible and send them to work. You fire them later. Only fire workers if you can replace him or her with a higher value one that will earn more.
Upgrade your building and purchase more floors.
Clothes
Based on your level and achievements in the game, you will have free clothing options. Do not spend coins on clothes unless you have lots of spare money.
Coins
Tap as much as and as fast as possible using multiple fingers.
Free workers
When you load in the tutorial and you want to get a business man (example) then when it asks you to hire your first free worker, hire the one it tells you to and then fire the one It told you to Hire. Then close the application and play the tutorial again until it says it to hire a worker for free again. Then repeat what I told you until it lets you hire the business man.
Library
The Library allows you to spend money to train your workers or play Pong. Pong is extremely difficult and usually will end up costing money. Training also is not a good choice, because you have to pay for your workers to get experience. Save your money and do not spend it at the Library.
Motel
Purchasing the Motel requires 65,000 coins. Start saving for it after getting three workers in your business and maximizing your Coin Upgrade multipliers menu. The Motel is the first house that you acquire and it opens more options.
Pets
Begin investing in pets after you have upgrades and everything else needed to make a steady profit. Pets will have people donate coins of a higher value. They are a good combination with Rush Hour. Pets are only used when you stay in the game and actually collect the coins dropped by people.
Tickets
Some challenges will require you things that you cannot complete until the time runs out. When this happens, use tickets to complete the challenge. Because the reward is two tickets, if you only have to spend one to complete the challenge you will still make a profit.
Upgrades
You can upgrade the Coin Upgrades, Power-ups and Pets and Places categories. Start with Coin Upgrades first to increase the amount of money you can earn. Start from top to the bottom, focusing on the multipliers because they will result in more coins per tap. Also upgrade The Mighty Toss must a few times for the same reason. Next, purchase the most profitable Passive Coin Upgrade. They will allow you to earn money while you are not tapping.
Next, consider some Power-ups. The Rush Hour Upgrade is probably the best, as it can be increased to give you more money and last longer. Rush Hours are very profitable.
