On the event page, you can "enter" events that are "scheduled/upcoming" or "ongoing."
Note: If the event is "scheduled," it will be a "pre-entry."
After participating in an event, you can join other events by waiting for 48 hours.
Notes
・The event score you have already earned in the previous event will remain with that event and will not be carried over to the new event you participate in.
・After applying to participate in another event via the entry button, the addition of event scores will begin in the newly joined event.
You can check which event you are currently participating in (where scores are being added) on the top left of the streaming screen (event rank icon) or in the "Events I'm Entered In" section on the "Ongoing" event page.
