In Idle Space Business Tycoon, you will build your wealth by building several businesses. These businesses start by partnering with a corporation, then creating the necessary facilities to produce the items that your corporate partner needs. You can create factories that produce raw materials such as ore and workshops that produce specific items such as steel beams and concrete. You can also upgrade your factories to increase the amount of money they make.
Other gameplay elements include the ability to take out loans from the bank if you need them, sponsorship deals that grant you a large amount of return on your investment, and advertisements that you can watch to earn extra in-game money. Also, if you feel that you're not making money fast enough, you can click the lightning bolt icon to speed up production. This is a good option when you have nothing else to do.
Another gameplay element to be aware of are gems. Gems will allow you to do a variety of things like speeding up the production of items, refreshing the market faster, and auto-opening boxes that contain special rewards.
Speaking of rewards, you can get additional rewards by logging into the game every day and by meeting certain milestones. This includes building a certain number of factories, using AI research, and buying a specific number of upgrades.
