To get the bonus balance on the real one, you need to make bets for the amount of the bonus multiplied by 20 (wager for 100 free spins). Wagering can only be done in slots at the expense of real money.
So, you give free spins with the condition of a wager of x20 with real money, i would say no thanks, that is not free spins, that is just a bait.
Let's say i win $100 with the freespins, then i have to wager $2000 so, i make a depo of $1000 for the wager, if i try to withdraw i will get stuck with your KYC policy:
9.12.4. If the requested amount exceeds one thousand US dollars (or in cases requiring verification), you must complete the identification procedure by sending us a copy or digital photograph of an identity document (a page with a photo), such as a passport, ID card, or a utility bill for verifying your address (except for your mobile phone bill). If you are making a deposit to your account using your credit card, you must send us a copy of both sides of the card. The first six digits and the last four digits of the card number must be clearly visible (if you have an embossed card number, the front and back of the card must have the same numbers); the CVV2 code must be covered;
That's why i prefer to stay away from your site, but good luck.
