I also think that a proper sportsbook would do the trick. It is much more excited to place bets, then watch to slots and see what the results it. Okay, there are certificates which makes it legit, but if we place bets on sports games, I have more the feeling it is controlled by human then only let the wheel spin by software.
I am not sure what to think about sports book on Wolf.bet, I think they will add crash and some other similar games first! It's like that direction, simple crypto gambling games with provably fair system. As I said earlier crash with expert settings would be great, limbo is something similar, but what to say, I like the animations of some crash games and limbo doesn't have it.
There will be no games added if there's no huge numbers of people requesting it to be added on their site since for user adding games take a lot of works and devs will surely look for demands before adding it on the platform, for now wolfbet is doing great maybe in due time those games mentioned will be seen added since for sure they need to join the demand to not get outdated to the current trend on gambling industry.
