Just went past silver 3 today and instead of opting cashback or freebet as reward, I tried opting for free spins on a slot just to check out my luck. I didn't had much luck earlier with slots but I got some nice wins with 6 free spins. Similarly few days ago I opted for 20 free spins and managed to get good win. Really some good slots in sportsbet, if anyone manages to get reward in case of tier rank-up, I suggest trying out the freespin options- its worth a shot and fun as well.
