I am sorry to say I could not use 100 feree spins though I have deposited more than the required deposit. Also tried to contact viqa live chat but still I could not get any support from them as I could not receive message from them. I have just got automated message from them.
I didn’t try it myself but according to their
bonuses terms you need to deposit at least $30 or its equivalent in other currencies. However, the minimum btc deposit to be eligible for the bonus (according to their terms) is 0.0005 btc which is equivalent to ~$50! The bonus will be credited automatically.
Also, you should know that the fs bonus will expire after 48 hours and you can use it only to play
Big Bass Bonanza. Maybe you tried to play other games!
