Hmm it seems like that will not happen because in my opinion wolf.bet site has had a fixed concept from the start, namely as a dice site. What's more they already have a certificate as a dice site from itechlabs.com. Well although there are many possibilities that will happen in the future, in my opinion the plan to add a new games is still very ambiguous.
Although a site had a fixed concept from the site but it may change on the process. Just look at other site, there are some sites with a "dice" on its domain name but the site decided to add other games than just a dice game. Its due to users opinion/suggestion or even request.
The fact is that adding new games in any case will attract a large audience of gamblers, because dice is a game of luck, and if you take for example card games, then in this case the result is more dependent on the user's real strategies and experience.
It depends what kind of card games you are talking about. There are many card games that based on pure luck, so no matter how great is your strategy or how great your experience then the result will be based on your own luck.
