At present casino games and traditional video games are undergoing some transformations and their qualities are fusing, borders are melting away and the delimitation between a gamer and online casino player is erasing by means of the modern technologies. Free casino games may compete for championship with any other kind of games, because apart from being fun they also can be used for training and, finally, for making money. It is enough to take a look at a casino games list and to see the range of offered entertainment. Next, casino games, just like any other kind of games, employ the full inventory of software development, existing now: all main programming languages and all flavors of web technologies. Of course, there are not only gambling software, which uses something like flash, but flash casino games are getting bigger popularity as there is no need to download them, i.e. they are fully cross-platform, which is handy for the most of online players.

In order to understand the whole structure of the existing casino games, it is sufficient to go to online directory listings of casinos and the games they advertise there: from bingo to roulette; one can see, for example, that bingo is one of the most dynamically developing game on the web, and bingo cards is a good proof for this. The other role of these online directories lies in their ability to serve as an online guide with the up to date news, freebies and events.
