After you reach the eighth level, temporary expeditions will become available. These comprise islands that are only available for a specific period of time. On the islands map, they are marked in the bottom part of the screen with a timer that shows how much time remains in the event. Players get a special reward for successfully completing these events.
Unfortunately, we won't be adding as many new locations for the time being as we have previously. We understand that this might be disappointing news, and we'd like to express our sincerest gratitude for your loyalty and support. You can still enjoy the locations and events that are already available and continue working on your Home Island.
