Thanks man! Just make sure to play the slots in good internet connection. I got a free spin bonus when playing a game there, but after the 1st spin, it didn't stop for like 5 minutes, and I decided to refresh it (not sure what steps should be taken in this kind of situation), and yes, as you probably have guessed, I lost the entire free spins. Of course I wasn't happy with that after spinning hundreds of spin until that bonus.
Internet connection is most important when playing games, slot games and more important if you are playing with your own money. You lost, but it is less painful because you lose with your freespins, not with your own money.
It is still a lesson and warning for many people, assess quality of Internet connection, before they start their playing session on casino with slot games. If the Internet connection is not good, try to find better places for better connection and if they can not have it, just don't playing as protecting your own money is most important.
