The full terms of the deposit bonus can be read here:

Anyway I found 1 thing that can be said as a bit different with other bonuses, this bonus will be credited once you wager your deposit 1x only.
Usually most other casinos will credit the bonus automatically once a player make the deposit without waiting for the player to wager the deposit 1x first.
If these standard requirements, which require 35x wagering, also apply to betting, then I think it would be very difficult for bettors to clear such a bonus. But on the other hand, I don't see anything surprising about this, as first deposit bonuses always have high wagering requirements. On the other hand, you get free spins, and maybe you'll be lucky enough to win some money. In any case, I consider this a promotion from the casino, a gift for players. So, thanks to Dustbit for this.
