But, why you did not use your 15 Free Spins?
In fact, I was on my Android phone and couldn't understand the site's functionality. So there was a problem. Now I am using my laptop and I have already used the 15 spins. I won approx 0.000038 BTC by using these 15 spins. And I've lost it too . But one thing I noticed is that your site's Minimum Withdrawal is really very high. 0.0024 BTC is really high IMO.
Could you post your feedback about experience on BitGame on our thread https://bitcointalk.org/index.php?topic=1745040.0?
I will give you another 15 Free Spins for this.
Thank you in advance.
