If you want to earn good cash bonuses keep an eye on the 'Goals' section of the interface and take part in the new objectives it gives you.
Deploying Robots
Click on your robots individually at the 'Market' section to view their role. Each robot will have an icon which which will tell you at a glace where they should be deployed. Use this information to plan your building moves.
Money
Always try and level up your robots whenever possible as the higher their level the more money they will generate.
Space
To free up space for more profitable ventures you can always sell and move awkwardly placed facilities. Although you won't get the full amount back when you sell it is better than nothing.
Upgrade Robots
Feed your robots produce created by the Snax Shacks to upgrade them. Although some foods take longer to produce than others they are worth making as they will provide a greater leveling bonus to the robot.
