This may make you wonder why anyone would choose to use the download option. Actually, no download slots serve a particular purpose and there are distinct advantages of both downloadable casinos and no download casinos.
The biggest reason for wanting no download slots is for security.
Many people are wary of downloading anything on their computer so when they see they will have to download their slots game, they get a bit nervous.
Most downloadable slots games are very secure though if you are dealing with a reputable company. However, for some, no download slots is essential.
For those who use Mac or Linux operating systems as opposed to Windows, many of the downloadable slots games are incompatible and will simply not run. So, in order to play online slots, no download slots options are a must.
Some casinos have a platform where you never download anything. These can be very advantageous to anyone who uses a computer from work, who is travelling or uses a computer without a Windows operating system.
These no download slots casinos often offer other games as well but slots are typically the most popular. You simply log in to your account, choose the game you want to play and then it is launched immediately in your browser.
However, many people believe the no download versions of these casinos offer fewer titles and are not as graphically advanced. For those graphically intense slots games, some complain that there is a lag in game play and it is not as sharp.
