But, I think the bonus only is eventually, only for the first deposit, or I missed the info about other bonuses?
If you are talking about the 100 free spins welcome bonus, then yes. That's a first deposit bonus only. Playgram's other promotion is the Drops & Wins. You can find information about this bonus campaign by clicking on the Promo button from your account. The monthly prize pool is €2 million and there are daily prize drops. You have to play selected Pragmatic Play slots to take part.
IMO, free-spin with 100 spin on "Big Bass Bonanza" was a really2 good offer for user. The reason, because these slot have less volatility and easy hitting scatter bonus making the user can have a good chance to build a balance at least 20$ for a good win.
Comparing to other pragmatic play slot, while usually over 120 spin most common hitting a bonus. The different Big Bass Bonanza, more often paying small like 30-50x and 100-200x multiplier result are usually rare. More than 300x are very2 rare.
Yeah, the free 100 spin bonus is really good for getting new user interested. For me personally, I don't really eager to multiply my bankroll, I just play for fun in gambling and I really happy when I got bonus like that, maybe I am a bonus hunter lol.
