While an event is active, the in-game card for events will display the rules on how to participate, when the event ends, and payout dates and times. The rule page can be reached by tapping on the event in the lobby. There are also sometimes additional explanation pages for events which can be found by tapping on the "?" or "!" icons on the main rule page.

Because events are generally tailored to players, it's recommended to view them while they are active.
