In most modern casino platforms, bonus continuity after login depends heavily on session persistence tied to the user account rather than the device being used. That’s why players often return to the exact same stage of a feature after a short disconnection or logout. The system typically stores bonus progress server-side, which reduces the risk of losing active rewards during interruptions. Another important factor is how timeout windows are handled, since some platforms allow inactive sessions to remain recoverable for a certain period before fully expiring. This design choice is especially important for bonus-driven gameplay, where even small interruptions could otherwise affect user engagement and overall experience flow.
