# Notifications

Notifications serve as a shared system that integrates seamlessly with multiple features, including Rewards, Leaderboards, Catalogs, Progressions, and Triggers. Acting as a central hub, Notifications track and communicate important player-related updates to the game, ensuring players stay informed about significant events and changes.

The system operates as a queue, where messages are stored until the game acknowledges them (marks them as read). This approach guarantees that no important information is missed, even if a player is offline when a notification is generated. Games can periodically check for new notifications and decide how and when to display them based on the player experience design.

{% hint style="info" %}
Unlike mobile push notifications that push messages directly to a player's device, LootLocker's Notifications are delivered to the game. This gives developers full control over how and when to present information to the player.
