Only events that feature quests and an exchange shop include a 24-hour exchange period.

• If an event does not have an exchange period, it will clearly display the message: “No additional exchange period.” In these cases, the event ends exactly as shown on the timer.
• Lucky Spin Events: When the event ends, a final pop-up window will appear, giving you one last chance to exchange your remaining currency. Once you close this window, the event is gone and cannot be revisited.
