No download casinos have a lot of benefits: your PC is cleaner, you don’t download from unknown sources (even if most online casinos are perfectly trustworthy), and you don’t waste time on downloading a game you don’t end up liking.
Instantaneous Play is exactly what it sounds like – you simply click the play button and you get to enjoy the game right after you sign in or make an account as a new player, which is also very quick. You need either Java or Flash in order to play, but if you don’t have either, the casino will direct you to a site where you can get them. The programs are small and useful, so it’s a good idea to download them.
Mac users enjoy the no download option the most, because a lot of casinos don’t even let them download software at all.
A disadvantage to playing no download games is the fact that you usually cannot play multiple games at once. You also cannot resize the window, which might be a problem if you care about this aspect.
There is no better or worse when it comes to software versus no download, it all comes down to individual preferences. For example people who care about having every single feature of a game will like software better.
It’s easy to find no download casinos by doing a simple search. 888.com is one of the most well-known ones.
