We've taken steps to make it harder to get disconnected from the real-time bonus rounds. Once your bonus credits are in play the bonus will happen even if your device gets disconnected. This is because other players are included in each bonus round and the round plays out for everyone at the same time.
Once the round is over, you will be forwarded a message with your winnings when you restart the app. Your prize will be a remaining chest, so play on a very strong connection next time if you would like to take a chance on Cleopatra's offer!
