Mini Store: Idle Tycoon is a casual idle game in which you can play with a fun twist. You’ll be in charge of setting prices, stocking your shelves, and serving customers in order to make money.

The gameplay is pretty simple: you need to click on the items you want to sell and be able to earn money for each of them. The amount you get for each item depends on what price you set and how much inventory space you have. You can also compete against other players in daily and weekly challenges, so you can see how well you do against them and improve your business.
