For the longest time, it had been the standard in the online casino industry for the customer to have to access the available games by way of a download of the casino software. This took up time and disk space, but other methods have produced an alternative to such a thing.
Downloadable casinos are great, because they offer a complete selection of the games that are available. But there are people who don't like to download things at all. They don't want to take up a lot of space on their drive, and they are also preoccupied with the idea that they might pick up viruses when they download any software. There is indeed an alternative t that.
The principal method by which somebody can play online casino games without having to download the casino software is by doing it through what is known as an 'instant play" version. This may also be referred to as a "no-download" casino. It is powered by Flash or Java, and it operates simply by the player logging in with their account (or in "Fun only" mode, with a registration) and playing. The games are easy to navigate, and they are very rich in terms of their graphic content. Indeed, many advances have been made, and online casino players have been the beneficiaries of it.
There is no doubt about the popularity of these games. Players certainly enjoy the convenience of having an alternative method to play, and in fact there is such a degree of popularity that some casinos (though not many of them) have gone with a format where they exclusively have instant play games. And as the technology continues to move forward, the quality level of these games is going to get better and better, which means they are only going to get more popular.
There is a drawback to this kind of format, and it is only fair that it be mentioned. It would appear to be somewhat cost-prohibitive for an online casino to place all their offerings into the instant play format, and as a result the selection of games that are available to be played through a browser does not approach that of the download version. Some online casino software providers make more instant play games available than others. But the idea that a no-download casino is much smaller than a download casino is generally very consistent. We would assume that the day will come when that is not the case, and that all games can be in the no-download format, and we will certainly look forward to that.
For the moment, however, operators of online gambling establishments will be content with the knowledge that they have the ability to offer the convenience, variety and choice to a customer who may want to play a different way, at least on occasion. And they will have more satisfied patrons as a result.
