Obviously, there is no promo code here, which makes me think the answer is not accurate. But from the bonuses page, it’s not possible to claim the free spins bonus. I guess you need to make a deposit first or the offer has already expired.
According to them, players should receive the free spins first, and they need to make a deposit to complete the wagering requirements. There are two types of wagering systems in casinos. One, the winnings get credited to your balance, and you can wager with the bonus winnings. Two: You have to make a deposit and complete the wager requirements, and only then your bonus winnings will be credited.
Galactix is using the 2nd method. But to get the free spins, you need some kind of promo code. As for making a deposit, that is a deposit match bonus. Not any kind of free spins. Even if they provide free spins on deposit, they should be available on the deposit page.
