A variety of offered products and/or services is one of main conditions to attract customers. In casino gambling business it is casino games first of all. Different online casinos offer different games, but the leading ones are poker, blackjack, and roulette. Less popular and therefore rare in online casinos are game of craps and baccarat. There are also about 10 special games in the world. However there are far more games in casino. Where do they come from? They appear due to different things:

1. Inventions.

Every year about 2-3 new author casino games appear on international exhibitions. In the beginning they attract casino operators by their uncommonness very much, who examine them, read incomprehensible rules carefully and try to play these now-how. But their interest gradually disappears. In fact these casino games are not interesting and sometimes can be difficult to understand not just for an ordinary casino player, but casino representative as well. Also many casino games require special equipment. Even if the owner places a table for such game, the customers of casino will be disappointed by it: "Too difficult, boring, not interesting". And frequently: "No chance".

2. Casino inventions.

From time to time the owner or employees of gaming houses invent quite interesting casino games. However, they have no future as well because of the above mentioned reasons: "I don't want to spend money to learn new games".

3. Innovations, based on the change of existing games.

In this case, to think of a new casino game, it is enough to change the rules of already existing one. So what makes casinos to introduce new casino games in the casinos? Are modern players bored with original version of roulette, blackjack and poker? Not at all. Except some kinds of poker, that are popular nowadays due to really interesting innovations, all new games are only small marketing help in casino promotions. They do not have any playing effect.

If a casino game is too complicated and casino wins a lot, players leave it at once. It is not interesting for the customers to play too simple and ineffective online casino games. Far more attractive for them are online casinos games with the history, such as roulette, queen of the games; poker, having many combinations; intellectual blackjack, having as many or even more combinations as poker games. Besides, if an online casino offers decent casino bonuses in a form of free casino cash, these online casino bonuses turn the house edge that normally exists in these casino games into a player edge over the house. That's why online casinos started disallowing some games form qualifying for the wagering requirements on their bonus offers. Online casinos that disallow blackjack from their casino bonus offers lose a lot of good customers. There are still many casinos that disallow blackjack from the wagering requirement qualifying play, but a player should always look at which games these casinos do allow, and play only if the house edge will be small enough on the allowed casino games to provide good money value for the casino bonus.

There is an opinion, that for the majority of players it is not so important what to play. The main thing for them is an atmosphere of a game. For example, roulette - people are trying to get to the bottom of this game for ages. Naturally it is easy to join them and try your luck.

As a result it appears that the same games such as roulette, blackjack, poker are popular in casino, and all the rest ones keep manager happy that there is "a variety of games" there. That is not bad at all, the main thing is that both players and employees of casino are satisfied.
