Arcades use various re-engagement notifications to keep players coming back. Here are the most common types:

1. Reward Reminders: Notifications about unclaimed rewards or bonuses, such as free plays or loyalty points, to incentivize return visits.

2. Time-Sensitive Offers: Limited-time discounts or special events, like "Double Points Hour," create urgency and encourage immediate action.

3. Personalized Messages: Tailored alerts based on player behavior, such as "We miss you!" or "Your favorite game is available now!"

4. Milestone Celebrations: Notifications congratulating players on achievements (e.g., high scores) to foster a sense of accomplishment.

5. Social Triggers: Alerts about friends' activities, like "Your friend just beat your score!" to spark competition and re-engagement.

These strategies help arcades maintain player interest and boost long-term retention.
