Is there any criteria that warrants them to actually give you these freebet so that maybe I can also follow up to know if they will give me also 
.
Another way you can get free bets is if you join Whale's contests and raffles, and they host a lot of them in the forum. Just look out for Whale's contests in the games and round section and if you check the rules and you are eligible, then you can participate and see if you get lucky..The thing I like much about this whale casino is for the fact when I withdraw am not charged any fee for withdrawals unlike some casino where there is extra token fees.
Yeah, it is one of the many good things about Whale.io casino.
