How do I run events?
To hold events, first select the activity with the required event, and tap the button with the calendar on it at the bottom of the screen, opening the events menu. Just like for products, you can drag events to the building to start producing if you have empty event slots, but instead of requiring supplies, events need specific items to be started. If you hold your finger over an unlocked event, you can see the items you need and how many of them you have in your warehouse. When an event is completed, you can collect it at the top of the event menu to get a coin and XP reward.
It’s important to note that different businesses can produce different items, you can hold different events at different activities and you can unlock up to three items or events by upgrading the building to the required level. If you don't see the events or products icon, you just need to complete a few more goals and it will unlock.
