You need to close a video game appropriately to keep its progress.

1. Save your progress in the game.

2. Click the Exit button in the game.

3. Wait at least 30 seconds up to 1 minute until the cloud is synchronized with Boosteroid.

4. Unless you need to click Exit in the game launcher, close the session via the "End Session" button in its overlay.

5. Wait at least 5 minutes before launching a new session.

At this point, the game's progress and achievements are sent to cloud servers of a corresponding digital platform (such as Origin, Steam) and stored there until you return to the game next time.
