If you get free spins from a game’s bonus round, your free spins will begin automatically and may be seen on the game screen. The end of the free spins round will result in your earnings being added to your bankroll. If you have received free spins through an offer, the online casino provides a direct link to the slot game and you can begin playing the free spins right away. Usually, once the free spins expire or you play through them all there is some kind of message notifying you that the spins are completed. If you begin playing free spins, but do not finish them, as long as you reload the game before the spins expire, you should be able to play any remaining spins.
