It's not an easy question to answer, as really no one know what the future holds, but if one needs to provide prediction, and according the the history (long and recent ones) the future is bright, and will continue to reach far and beyond, will be entrenched in many of our daily lives, and will be playable from multiple platforms.
The only question remains: will be where to play, and for what ? there are more games developed and designs, more places and websites to play, and more users and players joining it everyday. The comparison sites like Casino club will continue to provide best platforms to identify those proper sites, and in general, it seems, we will see more of the same, but in a much much bigger scale.
Granted, that's not really bold prediction, but rather common sense these days. But comparing these days to the past, online gambling shifted almost to mainstream, which is incredible to think, that more and more countries embracing it (and making money of taxes from it off course) it is now viewed as a cool cash game to play and have fun, and if someone wants to place his money and play for it, than why not.
First it was allowed only in Las Vegas and various other cities. Than, it made the transformation online, where the games online got dramatic boost, and now it is so popular and well known that most people don’t even remember what it was like before. Online gambling is here to stay, and will continue to developed, and once you find you game and site, you will notice it too.
