For your second deposit in 21nova casino you can get 60% bonus with 12x deposit + bonus wagering requirements. Of course I know that it is not so big for Playtech casino, but it is still good, with no any hidden terms, and with reasonable wagering requirements. And you will have 60% more money to play with, and it is not so bad.
I have claimed this bonus with 50$ deposit. Yes, why not, I have googled some reviews about this casino before and was sure that I will not have any problems if I win, so I was not fear to make 50$ deposit. Specially I love to make such deposits just after some good withdrawals from any other casinos, and then it is zero problem for me to play with such deposit.
I decided that I will play Captain treasure pro from beginning. I start playing 0.60 bets, and hit freespins feature just after about more than 100 spins. Due to the poor base game my balance was quite low, about 20$ and I had some really great hopes about this freespins feature. Expanding symbols was chosen captain himself, it is highest paying one, and usually it is very poor feature, or very good feature, and very rare something in the middle. Unfortunately it was very poor feature, get two captains only once, and few lines hits. Won about 10$, and just left this game with 30$ on my balance.
Next slot I decided to try was Archer, it is Playtech. It has 243 lines , and sometimes I had luck with it. But unfortunately not this time. I lost again, and even did not hit freespins feature.
I rate this bonus with 7 stars.
