We actually partly answer this in our “Why are mobile slots not as advanced as online slots?”.
Basically casino games providers have only just started, in the last couple of years, to convert their casino games from the standard online video slots to Apple and Android mobile and tablet device friendly versions.
Not all of them have done it successfully or particularly quickly. But as you can see from our ever growing selection of mobile slot reviews, every month we are seeing more and more new slot games being released on mobile.
If you imagine, a big casino software provider like Net Entertainment will have 100s of casino games. Of those, most have only converted a handful (usually less than 15) for mobile and tablets.
Old and New Slot Releases
Nowadays you are just as likely to see the latest new slots released on both mobile AND online. Not just one or the other. At the same time, game providers are playing catchup, trying to turn as many of their old classics into a workable mobile slot machine. Equally, mobile casinos are diversifying their selection of casino games, picking several providers to give them their games so they have as wide a selection of mobile slots and games as possible.
Some great examples, of online/mobile casinos that do it very well are Leo Vegas and Vera & John casinos.
It’s a work in progress, but one that is become more and more common.
